At Z Car Garage we love keeping Z’s on the road. From concours-level restorations to light refurbishments, making a client’s goals reality is our passion. Gary Roser brought his 1978 Datsun 280Z from Monterey, Ca for a full restoration, ZCG-style. Our Z Car Garage Big-BrakesZ Car Garage CV Axles along with a new drivetrain, full suspension and body restoration transformed this S30.

 

Our journey with Gary began 15 years ago and blossomed into a strong friendship. Gary and Rob recall their first meeting:

Gary: “In Oct/Nov 2007, after selling my ’99 Corvette I went online looking for Z Car restoration shops. I called Rob and introduced myself and discussed what he could do for me. Obviously he was very cautious in his response and made no promises. He also stated that he would have to see the car before he would consider taking on the job. My next move was to drive to San Jose and meet him in person. Needless to say I was immediately impressed with his shop cleanliness and the scope of his business. He also impressed me with his no-nonsense approach to our discussions and pulled no punches. Also, as a retired Marine, I noted with some degree of amusement his individual shop uniform. Fortunately for me he gave me a thumbs up, had it towed to his shop and off we went!”

Rob: “Gary came to ZCG when I was very young in my business ownership and asked me to restore his ‘78 280z. We were going to restore it as if Nissan didn’t have a budget. At the time we were really into the C8 Panasport wheels, doing 3L engines, KA24 5-speeds, and suspension work etc. I wanted to build Colonel Roser a car that we could both be proud of.”

 

He bought this Z brand new 1978 and absolutely adores it, being an integral part of his life for decades! Before going into the restoration work let’s take a look at the story behind Gary’s Z and his airborne career…

Fighter Pilot, Z Pilot

 

Gary: “I bought the car on June 4, 1978 at Terry Allen Autos in El Cajon, CA (just east of San Diego). The original window sticker, faded, but still readable: $9543.00. While shopping to replace my wife’s Ford station wagon with a Datsun 510 wagon I saw my black 280Z in the showroom. I needed that car like a hole in the head, as I already had a 1968 GTO convertible, stick shift, with air conditioning, that I had ordered just prior to leaving Vietnam in June, 1968. Anyway, I made an offer to buy both the Z and the 510. It took a lot of sweet talking to convince my wife that it was a good deal! I drove the Z regularly the first couple of years, putting 13,000 miles on in the first year”

 

“In February 1980, I received orders to move up the I 5 to MCAS El Toro, and back into a flying billet, flying A-4 Skyhawks. We bought a nice home in Mission Viejo and life was good. Then the winter rains came. We had a two car garage and the Z and the GTO occupied both stalls. It was a hard decision, but I put the GTO up for sale. I took command of Marine Attack Squadron 311 (Call sign Tomcats) in May of 1981. For my birthday, my wife got me the California License Plate: 311 TCATS which remains on the car today!”

 

“In the spring of 1982 I was approached by Jim Lau, the owner of The Foreign Works auto shop in Lake Forest, CA where I had been getting the Z serviced, about installing a turbo on the car. With 48,500 on the odometer, it was turbocharged with about 10 PSI of boost. I finished up my tour in 311, and then received overseas orders to Japan in July 1983. In July 1984 I returned stateside with orders to Washington, DC. I flew the family and pets to Virginia and then drove the Z across by myself. In 1986, after being promoted to Colonel, I fell in love with the new C4 corvettes, and just had to have one.” Below, Gary with his 280Z and C4 ‘Vette:

 

“After 4 years in DC, we headed back out to California for my final tour as Commanding Officer of Marine Air Group-42, located in Alameda. The Z Car had about 90,000 miles on her and the trip west was a hilarious adventure. As an aviator I was very used to radio communications, so I equipped all three cars with CB radios: I drove the corvette, my 18 year old son drove the Z, and my wife, daughter, and animals were in the OLDS. Needless to say, radio discipline broke down numerous times on the trip. I tried to keep everyone on a discreet channel, but the ladies liked talking to all the truckers. We safely made it to Alameda, and I spent the last two years(1988-90) flying my ass off. I had several squadrons in the air group, including a helo squadron. Not having any helo time prior to then, as Group Commanding Officer, I was able to get a little over 100 hours of helo flight time and I grew to have great respect and appreciation for their type of flying-it was a great way to finish my aviation career.” 

 

“I retired from the USMC and moved to Monterey, Ca in the fall of 1990 to take a staff position at the Naval Postgraduate School as the assistant Dean of Students for International Affairs. I bought a 1999 C5 Corvette convertible which became my primary driver and while I maintained the Z with regular checks, she sat most of the time. I needed to get rid of one of them and agonized over that decision. The Z car was in bad shape, rust and engine issues, and tired after 113,000+ miles, but my 27 year attachment kept tugging at me, and I just couldn’t let her go. I made the decision to sell the ‘Vette, and started looking into restoring the Z car. And that is how I met Rob Fuller…”

 

Above: The 280Z prior to restoration in 2007. Let’s dive in to the work…

Body/Chassis

 

We began the restoration process with body and chassis. Gary’s 1978 Datsun 280Z had severe rust issues. Many would have written this car off due to the extensive repair it needed but Z Car Garage and Williams’ Auto Body were tasked with the job of saving it. Photos below show multiple problem areas including frame rails on both sides, lower and upper radiator support, the quarter panel just under the rear quarter windows, door jams and rocker panels on both sides. More photos of the rust repair can be seen HERE.

 

Gary wanted the Z painted black and William worked his magic in 2009. The result was stunning, and remains just as slick to this day:

 

The front/rear bumpers were re-chromed. Following the body repair and paint, PQR-15 was applied to the interior and underside. We bagged/tagged every nut/bolt for plating along with fresh hydraulic lines:

   
Newly plated parts and suspension being mocked up. We love the gold (hydraulic) and silver (fuel) lines against the gorgeous black paint in the engine bay:

 

All front and rear suspension parts were powdercoated with struts/coil overs mocked up. Note additional plated hardware:

 

Drivetrain


Replacing the L28 in Gary’s 280Z is a 3.1L Rebello engine using factory fuel injection. Below you can see how the unsightly stock intake manifold was transformed into a thing of beauty…


Engine bay completed. See more in-progress photos in the gallery below:

 

To handle the power from the 3.1L engine we replaced the stock transmission with a Nissan KA24 (FS5W71C) transmission. This was a common swap (before the CD009a came to market) performed by modifying a 280Z L-series bell housing. The KA24 unit is significantly stronger than early S30 transmissions.

 
When we upgraded the transmission we also installed a JWT HD clutch with aluminum flywheel. Helping put the power down efficiently is a Quaife LSD. The R200 houses a 4.11 R&P assembled in-house (by our very own Joshua Corwin). Rounding out the drivetrain upgrades are a set of Z Car Garage CV Axles (shown below)

 
 

The factory EFI was updated with a fuel pressure change and custom tuning of the MAF. Gary’s car ripped, with the 3.1L making 190hp/205tq at the wheels… fantastic for a factory EFI car back in 2007. After driving and initial break-in we performed a valve adjustment and it just shined. It was awesome to see the Colonel driving and enjoying it again!

 

Interior

 

Following the body/paint restoration Gary visited Z Car Garage and he would find interior upgrades on other client/project cars for his 280Z:

“Over the next 5 years more work was done and “upgrades” became a common occurrence. I was like a kid in a candy store-let’s do Recaro Leather seats, power windows, power door locks, and hey let’s do power steering (absolutely love it). And a whole host of other things, including Autometer gauges recessed into the dash which I saw on another Z in Rob’s parking lot of Z’s.”

A complete dash restoration was performed with full HVAC/ducting and A/C refurbishment:

 

Autometer gauges, fresh wiring and re-furbished center console:

 

The power window and door lock conversion with more plated hardware:

 

Recaro Specialist seats in leather are our favorite upgrade to the S30 interior. Gary enjoys modern creature comforts like Bluetooth, back-up camera, power steering and full sound system:

 

The A/C compressor was upgraded to a Toyota unit that we like to use. All weatherstripping was replaced:

Suspension

 

The chassis was treated to a full suspension rebuild with new parts, bushings, Ground Control coil-overs (Koni struts with our spring rates) and ST sway bars front and rear:

 

Z Car Garage Big-Brakes

Gary has our ZCG Big-Brake kit. Not to be confused with our current Z Car Garage Big-Brakes (for small wheels), this Big-Brake kit was our initial setup from over a decade ago. This 328mm sized kit requires 17″ diameter wheels and the massive ST-42 calipers are finished in bright red. We actually did all the R&D in-house for this setup…using a 280ZX master cylinder and our own mounting brackets.


A few more detail shots of the Big-Brakes, they really pop behind the black Panasport wheels:

 
     
 

Since it was in its infancy we did not market or sell this BBK to the public, installing it only on our clients vehicles. There are about 20 sets of these early, 328mm BBKs on client Z cars like James’ Turbocharged L-Series 240ZScott’s 260zGary’s Datsunworks-Powered 240Z and Lou’s RHD FairladyZ:

 
 

Panasport Wheels

 

Gary also got a set of our custom Panasport Racing C8 wheels. These 3 piece, 17×8 wheels allowed fitment of a 255/40/17 tire under stock fender flares:

 

When ZCG was starting to build a series of RB-powered S30sRob brought in a pallet of C8 wheels destined for the builds. Gary wanted a set so we hooked him up and his desired black spokes with black anodized lip and hardware. They look great on his Z:

 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 200 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 
 

We built Gary a set of CV Axles, shown below:

 
 

Details

 

The little things are what we excel at. All window trim including quarter windows was powdercoated black at Gary’s request. This general “blacked-out” look was a point of contention:

Rob: “We had so many arguments over it…he wanted everything ‘murdered out’ and I suggested keeping the chrome/stainless, We fought tooth and nail and he always won…Gary outranks me since he’s a Colonel and I’m a civilian.”

The blacked-out theme carried on to many exterior parts like tail light bezels, side marker housings and the Z Car Garage license plate frame…even the white lettering changed to black:

 

The 280Z’s front/rear bumps did remain chrome after re-finishing. Below: More plating and hardware details:


HID headlights. Please check the gallery below for more detail shots, there are too many to list in this blog post!

 

Enjoying The Ride

With the restoration completed, we drove down to Monterey and delivered the 280Z to Colonel Gary:

 

Gary enjoyed driving the Z for a few years. It was hard not to grab attention with this s30…people were intrigued with the wheels, stance and of course that blacked-out look:

 

Gary: “Let me mention here that I get compliments on the car practically every day, many from thumbs up or yelling from cars and motorcycles in moving traffic.  Quite often folks want to see the engine, and when I raise the hood, people remark that it looks like a factory install and are absolutely amazed at how beautiful it is. William’s paint job still looks amazing as well.  I constantly get quotes like ” I used to have one of those, I am so sorry I ever got rid of it”; “what a beautiful Z, I just don’t see them on the road anymore”.  Best one though, was “Yes, I had one until one night I wrapped it around a tree and almost killed myself, but it was my favorite car”.  And when I tell them I am the original owner they are blown away.”

 

We attended several shows including the 2013 ZONC Annual Car Show in Brisbane, Ca and 2013 Silicon Valley Auto Show in San Jose:

 

In ~2015 a persistent electrical issue was traced to the wiring harness which led to an unorthodox (but exciting) solution:

Gary: “I was frustrated after the electrical problems. Rob explained to me we had to use a 1978 wiring harness to make everything work.  As I recall we changed out 3 wiring harnesses and even sent the computer module to San Diego to be reworked. Rob actually went to the Central Valley and purchased a 280Z for parts, so as to get another wiring harness. At that point I was thinking of other options and approached Rob about doing an engine swap, but that is a story for another day! “

Rob: “We located an unmolested harness and still couldn’t get it sorted. Colonel said ‘I love this car, but since we can’t solve this gremlin I want to do something different with it’. Years ago we were not into V8 Z cars until the LS-based engines came around. Perfect power delivery and balance…it just works in Japanese (and other) platforms. We had done Ben Sutton’s LS-powered FD RX-7 and it worked really well with incredible torque. The Colonel talked us into it… ‘There’s two loves in my life: I love my corvette and I love my Z car.’ We had to bridge the two together for him.”

LS3 V8 Power

 

Gary:  Well, after three tries I just didn’t see a way forward with the Nissan motor, and asked Rob about doing a V-8 conversion. He had not done an engine swap, so he was cautiously optimistic about trying one. In his typical attention to detail fashion, he did a lot of research, found a way forward, and off we went.  Lots of growing pains, and a few curve balls, but the end result has been spectacular!”

Rob: “We did an LS3 swap, our first V8 S30 conversion ZCG performed start to finish. Super proud of it. There were some initial teething issues: a larger twin-fan radiator eliminated cooling problems and our upgraded ZCG CV Axles solved axle issues. We de-tuned the LS3 to give the Colonel a Z car that is fast but but also reliable.”

The LS3-crate motor came with a warranty from GM and weighs less than the L-Series engine it replaced. Engine and 6-speed transmission were installed using the Hoke Performance kit:

 

The larger, twin-fan radiator and A/C plumbing and wiring:

 

Ovalized exhaust from headers to catalytic converter help with ground clearance:

 

Dyno Tuning

The LS3/6-speed T56 drivetrain was dyno tuned after installation, making 405hp/410tq at the wheels, a significant increase of 115hp/206tq compared to the L-Series:

 

Enjoy this video with dyno run, in-car driving, cruising and fly-by action with Gary’s LS3-powered 280Z:

 

We love how happy Gary is with his V8-powered Z:

Gary: The car is an absolute gas to drive. I will tell you up front that it is not a refined ride. The suspension is tight and pretty stiff, but gives you great road feel. The T-56 6 speed transmission, mated to the LS-3, required some getting used to, but is solid and efficient. The turning and maneuvering capability of the car in its two dimensional environment is terrific. It reminds me of when I did aerobatic maneuvering in the A-4 SkyHawk! What can I say about the power and torque the engine puts out-405 HP at the wheels!”

 

“I have had my way with a lot of other fast cars, and even a motorcycle who tried to take me on, who have no idea what is under the hood of my little Z Car. (Sometimes the wide tires give me away!)  Best acceleration is in 2nd and 3rd gear.  I don’t like to take it much over 90 mph, because the front end gets a little lifty. (I have over 4000 hours in fighter and attack aircraft, and I know what lift off feels like, so I don’t need to get airborne again!)”

Thank You Colonel Roser


Rob: “We have so many great stories with Colonel Gary. He’s more than a client, somebody we really admire and look up to. Such a fan of his. My father was so proud to be a Marine and Colonel understood this with his Military background.”

 

Gary: “I will be 81 in May and I don’t see another adventure like this one in my future so let me comment about Rob Fuller and his Z Car Garage. We have been friends now for 15 years. We have been on this journey together, through all the ups and downs and twists and turns. He has been there for me every single time, night or day. I just can’t imagine there is another car guy out there who would have had the compassion and understanding to shepherd me and my Z Car through this adventure.”

Below: Colonel Gary Roser and Rob on May 23, 2023

 

“Over these 15 years I have watched his business expand and grow, and am amazed at the breadth and width of his knowledge and his reputation in the auto industry. His leadership skills and the way he runs his shop is suitably impressive, and he has good people working for him.  And, by the way, he is a pretty topnotch driver as well. With him at the wheel and aggressively putting my Z Car through its paces, I am reminded of my fighter pilot days when I could fly an airplane like he drives my car. In another time and place I would have been honored to have him fly on my wing.”

Enjoy The Ride Gary and Long Live The Z!

Our Z Car Garage Big Brakes have been winning over Z-car enthusiasts locally and globally. Kim recently purchased a set for his 1970 Datsun 240Z and performed the installation himself at home in Norway. Before we go into his Big-Brake experience let’s hear his Z-story…

 

Like many enthusiasts, Kim started with a Miata…

“After owning a modified Miata for several years it was time for another project car. I still have the Miata, but that is more for track use now. I was not actively looking for a 240z, but I came across my Z car on a Norwegian sales site. I went to have a look and the car was in good shape, and the price was so low that I just had to buy it. It was repainted in 2005. The paint job was ok, but not perfect. All interior panels, dash and seats were re-trimmed in leather.”

 

Modifications include Tokico dampers with Ground Control coil-overs and a Nissan 6-speed CD009a transmission using the Hoke Performance kit. Kim was heading to the track and eventually installed a Datsun Spirit 3.1L engine with Jenvey ITB EFI, ported head and custom exhaust. Yes, that’s Kim’s Z on the Nurburging!

 

You can see the dyno run and acceleration in Kim’s Z in the video below:

See the full video from Misha Choudrin.

Z Car Garage Big-Brakes

 
 

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel and retaining factory emergency brake lever! A few details below:

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.

 
 

Big-Brake Kits Available For DIY Install!

Z Car Garage is proud to offer our Big-Brake Kit to Z-Car owners that want to perform the installation themselves. We can ship worldwide and each kit contains everything needed with a comprehensive (40-page) installation guide. Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. Enjoy these pictures of Kim’s beautiful Series 1 S30 and his ZCG Big-Brake installation:

 

As mentioned, our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake. Kim successfully installed the BBK on his Z, and they also look great behind the Work Equip 03 wheels and newly installed fender flares:

 

“I had a brake kit from Silver Mine Motors and used those for several years. With the new engine and higher HP numbers I really needed a brake upgrade. StopTech from Z Car Gar Garage was the way to go. The installation was quite easy. I did have some questions, and I got answers really fast. They feel awesome.”

 
 

Beyond ease of installation and quality components, our Big-Brakes perform by offering superb pedal feel…everyone that drives our demo Z confirms! This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments.


What’s in store for Kim’s Z?

“I take everything as they come, and find a new upgrade I like to try from time to time. Well, the goal is to have a car that works every year and I can modify during the winter. All lights are upgraded to LED from Classic Car Leds. AC from Vintage Air, upgrading the engine wiring harness, and consider some wider tires to fill the arches a bit more.”

 

Thanks for your support Kim we love that you are Enjoying The Ride and Long Live The Z! More photos in the gallery below

Trevor’s Datsun 1978 Datsun 280Z

Filed under: 240z,280Z,Featured Cars and Projects,Parts,Performance
by Alvin G @ 9:29 pm on June 18, 2021

 

We promised our readers a full, zcarblog.com report on Trevor’s 280Z after it was featured on Hoonigan Autofocus with Larry Chen. Let’s take a closer look at this fantastic daily driver+canyon carver showcasing our Z Car Garage Big-Brakes, Z Car Garage CV Axles, CD009 Six-speed transmission and more.

 

The Next Big Thing

 

It’s no secret that S30 chassis values have skyrocketed in the past few years. While the 240Z commands top dollar it has become out of reach for many enthusiasts. Not to worry, Datsun offered the 260Z/280Z models and both are great, attainable chassis in the S30 world. Trevor shares how he found his 280Z:

“I met my Z in almost completely stock form with 94k original miles. I travel for work, ending up in a new town every 6 months or so. As soon as I had an inkling of where I was going to be sent next, I would start hitting the internet classifieds for a 280z. While the 240z had seductive weight savings over the later versions, my attention turned to the 280z for its fuel injection (with constant travel I didn’t want to have to tune carbs), it’s price/ availability, and they are easier to find with air conditioning.” Below, left is the night Trevor bought his Z:

 

“I found my silver Z in Phoenix, Arizona. The only things it had on it that weren’t original from the Hiratsuka factory were the wheels, springs, and Toyota 4×4 front brake calipers. The rest of it was stock, and most importantly, complete. I did a little work to get it running smoother, basically replaced all maintenance items and swapped out a few sensors that weren’t working, and then drove it as much as I possibly could.”

 

Trevor was looking for a shop to take care of his 1978 Datsun 240z and heard about ZCG from a shop tour with Larry Chen on this episode of Hoonigan Autofocus (Thanks Larry!). Trevor brought the Z in last summer and we performed a full inspection before upgrades.

“I chose to send my Z to Z Car Garage after watching Larry Chen’s Autofocus episode on the shop. I could really tell that Rob had a ton of passion for what he does and I knew I could have confidence with him at the helm. Before I had showed up at the shop, Rob and I had talked on the phone about doing the brakes, control arms all the way around, and a couple of other smaller things. I wanted it to handle as best as it possibly could and that meant stopping when it should and having the adjustability in the control arms to set up a proper alignment. ” 

 

ZCG Big-Brakes and CV Axles

We handed Trevor the keys to “Mrs. Butters”, our 1971 Series 1 240z shop demo car and he was sold on our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 Read below for a brief description of these parts:

    
 

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever! A few details below:

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.

A few closer detail shots of the calipers, rotors and hardware:

 

We removed Trevor’s existing brakes and installed our ZCG Big-Brake kit. The stock suspension (with Tokico struts/Eibach springs) was replaced by Apex Engineered parts, as supplied by Trevor. Shown below are front/rear control arms and T/C rods being installed, more pictures in the gallery:

 
 

Front control arms and TC rods:

 
 

ZCG Big-brakes replacing the Toyota 4×4 caliper setup:

 
     
At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!

   
 

 

Trevor is impressed with the braking performance:

“I quickly found out that even after just a short spirited mountain drive, the Toyota brakes would get hot and fade. It didn’t help that after getting a taste for driving her quickly, I wanted to do a few track days in the future. I knew I wanted a brake upgrade, one that I would only have to do once. After getting back to Southern California I was really able to put the car through its paces on the canyon roads. The ZCG Big-Brakes proved their worth and were consistent and didn’t fade even after a few good rips up and down the mountains. This car sticks to the road insanely well. With the alignment and new tires it just carves.”

Z Car Garage CV Axles

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 130 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

Trevor has CV Axle set #335. Stock half shafts (L) and ZCG units:

 

More pictures of the ZCG axles installed, also visible is the ZCG Exhaust system:

Panasport Wheels

Complementing the new Big-Brakes on Trevor’s Z are Panasport wheels! We replaced the aftermarket wheels with 16×7 Panasports and sticky Bridgestone RE-71R tires in 225/50/16. The Z was fully aligned:

Engine

We knew the car would be stopping and handling better than before, so we installed a Moroso oil pan and Koyo aluminum radiator to keep temperatures in check. Other than cooling and fuel system work, the engine was largely untouched to maintain factory reliability.

 

We replaced intake and exhaust manifold gaskets with factory Nissan parts and few ZCG tricks including a certain exhaust nut and exhaust stud.The exhaust manifold was replaced with a Pacesetter header ( to clear six-speed) leading to our ZCG exhaust system with stainless resonator and slash-cut tip.

 

Dyno Tuning

Rob dyno tuned the L28 with OEM EFI. Baseline was 133hp/149tq and with Rob’s tuning it made 143hp/159tq at the wheels:

 

Enjoy the dyno run video below:

Driveline Upgrades

We built Trevor an OS Giken LSD, a perfect upgrade for anyone doing spirited driving.

“As with the brakes, I figured the best way to do the driveline was once so I also went with an OS Giken LSD and Z Car Garage CV axles.”

 
 

We changed the final drive, installing a R180 4.11 OSG LSD built in in-house:

   
 

The clutch hydraulics were replaced to work with new aluminum flywheel/JWT HD clutch combo:

Six Speed Transmission

Next on the update list, we were really excited to install a Nissan 350z 6-speed manual transmission behind the L-series in Trevor’s Z. You read that right! S30 owners can now bolt-in this robust, 6-speed manual behind their L-series engine!  You might remember our first application of Austin Hoke’s custom 6-speed adapter kit on the OS Giken TC24B1Z-powered 240z:

 
 

Using the 6-speed conversion kit from Hoke Performance we installed a new CD009a transmission from the 2003 -2008 Z33 in Trevor’s 280Z:

 
 

Here is the brand-new transmission from Nissan being unboxed:

 

The kit necessitated exhaust header changes and after testing a variety of headers we found the Pacesetter 6-2-1 unit provided enough clearance. Serial 9 provided the shifter relocation assembly and we are really happy with its performance. Also shown is the aluminum driveshaft.

 

 

It fits! More installation pictures in the gallery. It’s a very discreet look from the cockpit…until you feel the amazingly direct and precise feel of the CD009a!

 

Trevor is in love with the six-speed, we are as well:

“I had done my absolute best to convince myself that I didn’t need a transmission swap and my wallet and I were on the same page as I went to drop the Z off at Z Car Garage. Where my wallet and I started to have a disagreement was after Rob let me take Butters for a spin. After feeling the CD009 perform there was zero chance I was going to get my car back without one on the back of my L28. However, the more I was driving the car in the twisties, the more I started to become unhappy with the uneven gear ratio gaps between shifts.” 

Details

We sorted out little things for Trevor like making his Speedhut tach and speedo functional. The car was fully detailed:

 
 

The Z was cut/buffed with a detail from JB mobile detail.  We’ve worked with Veto at JB for years and he’s a big Z car enthusiast:

 

Driving is Believing

When Trevor picked up car, he was blown away:

The car I got back is a totally different machine from the one I had dropped off. The result of the perfect combination of driveline parts is a sore face caused by either smiling the entire time or from your face almost leaving your head as Rob shows you just how well the brake kit works. Rob also threw her on the dyno and finally got the stock system performing perfectly. I’m sure it’s making more power than it did even new back in ’78.”

 
 

The Z was recently featured on Hoonigan Autofocus with Larry Chen. Larry and Rob discuss the work ZCG performed and take it for a spin. Watch the video to get an idea of the six-speed and power from Trevor’s280Z:

 

We enjoyed working with Trevor and he’s been Enjoying The Ride in his Z:

“I had flown up from the LA area where I was working to the shop in San Jose. My plan was to drive the car back down the PCH to get a feel for my new machine. I couldn’t believe how much fun the car was to drive on curvy roads. The CD009 feels great behind my L28. The shift pattern is short and precise, it’s fantastic. The rear end has no play and pairs nicely to the race feel of the CD009. One of the best parts of the combo is how easy it is to drive. It feels like you have a race car transmission but with the ease of use of a street car.”

 

 

“She’s back at Z Car Garage right now as my job has me in Omaha for the rest of the year. I have been talking to my wallet about coil overs and maybe an engine build while the car is in San Jose. My Z and I are apart right now but I cannot wait until I’m able to eat up more miles with her. She is a wicked joy.”

 

Thank you for entrusting us with your S30, Trevor. We are so fortunate to work with owners that appreciate the Z and believe in our ability to make them better! LONG LIVE THE Z!

Kai’s 1972 Datsun 240Z

Filed under: 240z,Featured Cars and Projects,Parts,Performance

Many of our clients perform work on their Z cars by themselves, and we love to help when they are ready. Kai N installed a bunch of parts on his 1972 Datsun 240Z and got to the point where he didn’t feel comfortable taking it further. He took his Z to several local shops and was not getting it sorted so he visited Z Car Garage. We got him dialed in by sorting out his Weber carbs, brakes and fuel system. Our ZCG Heat Shield also graces his induction setup.

 

“A while back I installed triple DCOEs, headers and exhaust. I got some professional help to get the car running, but it was not quite right, so I knew my next call would be to ZCG. But before I made the call the pandemic hit, I found myself with a bit more free time and started working on other bits of the car. I ended up working on the cooling system (new radiator, electric fans), fuel system (electric fuel pump), new brakes and suspension.”

 

Z in the Family

Kai shares his Z history:

“The Z belonged to my Uncle Donnie until the late 90’s. He sold the car to our local mechanic. I’ve always wanted a Z and my Dad always reminded me where I could find Uncle Donnie’s old Z if I was ever ready to own one. When I was finally able to acquire my dream car in 2017, I asked the mechanic a few times if he would sell me the car while I was shopping for a Z, but he was on the fence about it. BTW I think he had 2 or 3 Zs at the time. After a few months of me bugging him, a generous offer and my uncle (along with his friends) putting in a few good words on my behalf, he was finally convinced to sell me the car.”

“I will never forget that after I purchased the Z, my Dad told me a story. Before my uncle sold the car to the mechanic; Uncle Donnie had asked my Dad if he wanted the Z. I was a few years from being old enough to drive and the Z could have been my first car. Of course, my Dad declined the offer. I got my Z, it just happened 20ish years (and a lot of $) late.”

 

Mechanical Sorting

 
 

Kai wanted us to address a list of items and we knocked each one out. Littles things like installing a temperature sensor, replacing motor and transmission mounts, re-wiring his fuel pump and new rack bushings were taken care of. We also sorted out his braking system and nut/bolted the entire suspension followed by a full alignment.

 

The engine bay was cleaned up, drive belt replaced and we sorted the Weber carbs. Kai purchased one of our Z Car Garage Heat Shields and we modified it to work with his throttle cable linkage:

 

More info on our ZCG Heat Shield below:

ZCG Heat Shield

We are excited to offer the Z Car Garage Heat Shield for your triple-carb’d L-series Z car. This is a one-piece 304 stainless unit with laser-etched serial number. Proven on all of our L-series engine builds and dyno testing.

 
 

This heat shield will fit Mikuni, Weber, Dellorto and Jenvey induction with several intake manifolds like the Harada:

 
 

Dyno Tuning

 

The triple Webers were dialed in on the dyno. With Rob’s tuning the Z went from running poorly to running well, making 141hp/141tq to the wheels:

 

Listen to that L-Series music on the dyno:

Kai is really happy with the work we performed:

“It’s a completely different car. It still needs work, but I can finally enjoy the car. I didn’t want a track car or a pristine show car, I simply wanted my Z to be something that I could enjoy. ZCG brought the joy. My Z’s journey isn’t done, it will continue to evolve and I’ll be counting on ZCGs help. I approached ZCG without much of a plan. I think Rob and crew formulated and executed the perfect plan for me (and my budget). The car is fun and safe, while having potential for more growth.  I had not driven the car in 2 years, So I’m sure you can imagine how happy I was.”

 

What’s next for Kai’s Z? He’s driven Mrs. Butters, our 1971 shop 240Z and he is returning to ZCG for our ZCG Big Brakes!

“My experience at ZCG has been amazing, I’m pumped for the next step in my car’s journey. ZCG BBK is next for me! Also being at the shop is cool too, there is always something there that blows my mind (like the BRE Z or the IMSA).”

 

Thanks for your support Kai, we are honored to be a part of your Z car journey!






Vince S called Z Car Garage after he scored this 1973 Datsun 240Z from our friends at Bring a Trailer. After we got the Z up here from SoCal we found that it needed some work for Vince to really Enjoy The Ride. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with a full suspension refresh and engine tuning make it just right.

 

Z Destiny

Before we explore the upgrades, let’s take a look at how Vince found his Z car…

“I’m incredibly lucky to own my Z. It was sold new in Decatur, IL on August 10, 1973. The car was supposedly purchased from the 2nd owner who reportedly had it for over 30 years in 2018 by a dealer in Oakland who then sold it to the collector I bought it from. I first saw the car in 2019 parked in my neighbor’s driveway. At the time, I was looking for a 240Z to buy. In high school I had a 1978 280Z that I took to college but it was prone to overheating and I blew a head gasket and didn’t have the money to fix it. I sold it in 1990 and regretted it ever since. So, when I saw a 1973 240Z sitting in that driveway, I knocked on my neighbor’s door and asked if he wanted to sell it.”

“Turns out the Z didn’t belong to him. He was transporting it from Oakland to Carmel and then on to L.A. for a friend who was a collector. The friend already owned two 240Zs (he has one of the 37 Zs that were part of Nissan’s Vintage Restoration Program) and he wanted my Z for it’s a/c components and other bits to complete one of his cars (he later decided it was too good of a car to use for parts). Although I couldn’t buy my Z that day, my neighbor let me go for a quick drive around the block. Fast forward to April 2020 and that very same Z is being auctioned on Bring a Trailer.”

 

Vince watched the auction, confirming with the seller that it was the same car he had driven. Although he was outbid, 20 minutes after the auction ended the seller informed Vince that the winner backed out. They agreed on a price and he became the proud new owner of the 240Z.

 
 

Chassis and Suspension Upgrades

 

With Vince’s Z finally at the shop we proceeded with upgrades to make it a fantastic, reliable driver. For our clients that are cruising with occasional “spirited” driving we installed our “Stage 1/light street” suspension.  New parts from Techno Toy Tuning included adjustable T/C rods and rear lower control arms. We really appreciate Gabriel and his staff at T3. They make some of the best suspension parts out there for Z cars.


A full front suspension rebuild included new rack bushings, front control arm bushings, ball-joints, tie-rods, new wheel bearings front and rear (OEM genuine Nissan seals/parts), KYB strut inserts, Eibach lowering springs trimmed Macpherson bumps stops for full travel and a ST sway bar set.

 
 

ZCG Big-Brakes and CV Axles

Brakes: every vintage Z car that we build here gets the ultimate setup: our Z Car Garage Big-Brakes for small wheels.  Everyone that drives our 1971 Series 1 240z shop demo car is sold on our Z Car Garage Big-Brakes  and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 Read below for a brief description of these parts:

    
 

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever! A few details below: Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized) Rotors: 280mm x 20.6 with Alum 7075 hats Pads: Stoptech 309 sport street pads Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. A few closer detail shots of the calipers, rotors and hardware:

 
 

We removed Vince’s brakes and installed our ZCG Big-Brake kit with a new brake master cylinder from Nissan, rebuilt brake booster and parking brake assembly.

 At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!

 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 90 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 
 

Vince has CV Axle set #341. Stock half shafts (L) and ZCG units:

  
 

ZCG CV axles installed:

 

Panasport Wheels

Complementing the new springs and shocks on Vince’s Z are Panasport wheels! We replaced the stock steel wheels (kept for shows) with 16×7 Panasports and Continental Extreme Contact Sport tires in 225/50/16.

 

 

Drivetrain

We performed a full drivetrain inspection with compression/leakdown test to make sure the engine was healthy. A list of items that were addressed/replaced: sparks plugs, new plug wire set, fuel filter, valve cover gasket, valve adjustment, MSA 6 to 1 header to our ZCG exhaust system and Z therapy carbs. More pictures in the gallery!

A Koyo race aluminum radiator replaced the stock unit:

   
 

All coolant hoses were replaced, new water pump, fan clutch, fan blade, all new drive belts, new battery hold-down/cables and a e…we even lubed chokes cable everything to make this car a solid driver… everything to allow Vince to just hop in to his vintage Z and enjoy some back roads. The aging 4-speed transmission was replaced with a 5-speed from our parts stash.

 

This early 280z 5-speed. came in the 1977-78 S30s and has the same gearset with an 0.86 overdrive perfect for the factory rear end. Our go-t0 JWT alum flywheel/clutch back the engine:

 

Dyno Tuning

With fresh Z Therapy carbs and MSD Blaster 2 coil with Pertronix ignition Rob set the AFR/timing for best performance and drivability. Rob dyno tuned the L24, now making 138hp/139tq at the wheels:

 
 

Vince is throughly impressed and happy with all of the chassis and engine upgrades:

“My experience with Rob and ZCG has been exceptional. When I bought my Z, it was essentially stock with the exception of one or two paint resprays of the 113 green and an added electric fuel pump. It was clear the car had a fair amount of deferred maintenance, I knew I needed to improve both its drivability and reliability.  So, I upgraded to the ZCG Big Brakes, ZCG CV axles, did a full suspension rebuild and drivetrain refresh.  Well worth the wait…The Z I picked up was nothing like the Z I dropped off — it was better in every way.”

Enjoying the Ride

 

We loved to hear that Vince is out an about with his Z. He attended the Valt gathering in Albany where our friend Geoff snapped these pictures. He also just completed a rally with Breakfast Club Rally group:

“The 2nd best road trip was a recent 100 mile rally in the east bay foothills and my daughter rode with me for that as well. She shares my love of cars and passion for Zs. It reminds me of the times I shared with my dad who could fix anything on wheels and for years owned his own repair shop. That’s why this Z is so important. As much as I appreciate the beauty of its design and brilliance of its engineering, it’s the memories I have and will make that I cherish most”

      

Welcome Back to the Z car family!

“My Z performs far better than I expected. I just did my first 100-mile rally and had complete confidence that the car would go, turn and stop like I needed and expected it to. This isn’t my first Z but it’s my first 240 and first major mechanical refresh of a car. As they say, “you don’t know what you don’t know,” so I really valued (and needed) Rob’s experience and advice. My Z means a lot to me (my daughters joke that she’s the favorite in the family) and it was important to do things right. It’s not that money wasn’t an object but I was willing to invest in the things that mattered most, which is what Rob and the crew helped me do.”

 
Thank you for your support and we loved working with you Vince!  Happy that you are a Z car owner again, welcome back to the family and LONG LIVE THE Z!
