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. Richard W brought his 1971 Datsun 240Z from Eureka, Ca for a full mechanical restoration, ZCG-style. Our Z Car Garage Big-BrakesZ Car Garage CV Axles and Z Car Garage Heat Shield along with a new drivetrain and full suspension transformed this Series 1 S30.

 
 

In 2017 Richard contacted us to inquire about restoration work. He understood we were booked, and we spoke again later, but this time he visited the shop with a photo album filled with photos of his beautiful, Sunshine Yellow Z.

“I did my due diligence and researched what ZCG could do, and arranged for a meeting with Rob to discuss my car. I asked if he would be interested in restoring my 1970 240 Z.  He was pretty adamant, ‘I don’t restore those rust buckets anymore.’ A little disheartened but I persisted. Would you take a look at the album I have of my car? He flipped through he pages and you could see him light up and the enthusiasm came forth. He said, ‘Where is the rust?’. I told him there was none as the car has been indoors for the last 40 years.”

 

Rob and Richard agreed that since the exterior was in great shape ZCG would perform a mechanical restoration. Richard is in his 70’s and still practices dentistry in the small town of Eureka. After being parked for decades he trailered the Z down and arrived at ZCG in January 2018 . Here is VIN #12291, with 63k original miles:

 

He bought this Z brand new 12/70 and absolutely adores it, being an integral part of his life for half a century! We love the story behind Richard’s Z lets’ take a look before going into the mechanical work…

Life With The Z

 

“We all have defining moments in our lives and those moments need to be prioritized. The marriage to my wife of 50+ years is of course the most important moment. She provided the resources to live in San Francisco and was so supportive of my graduation from college. That same year she became pregnant with our first born. We moved to Eureka at the same time. I was able to start my own business in 1970 and begin an adult life. All the important hurdles were checked off. We moved to Eureka with $300 in our pocket and a mountain of debt. But wait, there was one more hurdle…”

 

“…From across a parking lot, in Eureka no less, stood a bright yellow Ferrari. Upon closer inspection I was even more baffled. What was a Datsun 240Z?  I went to the local Datsun agency, long before Nissan came along and made my inquiry. Yes, the new 240Zs are very special and very desirable. They were being shipped in but there is a waiting list. Just add my name.  Sure enough they called a few weeks later and said there was an Orange Z on the lot. They made the mistake of letting me wring that car out and I was sold. While I was in school in San Francisco, I saw Cobras and Porsches that cost $6 – $7,000. Way out of my league but I could afford the $3,600 Z. Even if it meant borrowing $1,200. In early December 1970 I took possession of my Z. It became my car and my identity. It has remained just that for the last 50 years.

 

“My oldest son was born the following February. Now all the pieces for my life fell into place. Marriage, college, moving to a permanent home, birth of our son and the final piece, my sports car. Being a young family in the ‘70s was simple. We just put Jason between our two seats the Bull Dog in the back and off we drove. No thought of a car seat. Before he was six months old, we had been the 700 miles to San Diego and the 700 miles to Canada. Not a care in the world and a wonderful way to see the country.” 

 

“My car was a daily driver. For the next 20 + years that was my car. As my boys grew up and learned to drive, I needed to provide a car for them for high school. Well, not my car.  So, I bought them an upgraded and modified ’71 240Z. I bought the Z because I felt they would be safer in that car. I didn’t want a larger car they would put a lot of friends in. Later on, I heard they actually had put 5 guys in the Z car.” 

 

Of course, over time, tastes changed and Richard succumbed to buying a 1992 Corvette. You know, the ones you fall into and climb out of. Fast forward to 2015 and his 240Z is in the garage, covered with the things a guy collects in a garage. The ‘vette became useless and the family all preferred the Z. This is where ZCG becomes part of Richard’s Z car journey. Let the mechanical restoration begin on this Series 1 that has not run since 1985…

Drivetrain

 

We got the original L24 with SUs running after sitting for years, but Richard wanted more power and Rob suggested a Rebello 3.1L engine. Supporting parts included an MSA 6-into-1 header, ZCG exhaust system, internally regulated 280ZX alternator, 280ZX gear reduction starter, KOYO race radiator (custom upper hose) and Z Car Garage Heat Shield. Here are a few pictures of the engine build/installation with many more in the gallery:

 

Powdercoated and plated parts adorn the engine:

 

Induction is handled by triple-Mikuni PH44 carbs on a Harada intake manifold.

 
 
 

Beneath the triple-Mikunis is our Z Car Garage Heat Shield, serial #00250:


 Before/After the engine bay restoration, more details 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 an OS Giken LSD. The R180 houses a 4.11 R&P and the assembly is setup in-house (by Joshua Corwin). Rounding out the drivetrain upgrades are a set of Z Car Garage CV Axles (shown below)

 
 

Engine Bay Services

Richard’s Z received a total engine bay restoration. Please visit the gallery below for more pictures documenting the engine bay restoration work, it’s where our efforts shine!

 

With the engine/transmission removed we focused our efforts on restoring the engine bay.  Everything was cad plated or powdercoated.  All new fuel hoses, every cooling hose and all new hydraulic lines. Every nut/bolt is bagged and tagged before re-plating.

   
 

The Z’s body had been painted once before but the engine bay was left un-touched. We called upon our man William from William’s Auto Body re-spray the 919 Sunshine Yellow and it turned out fantastic. Before/After:

 
   
 
More before/after shots showing fuel pump, hydraulic an coolant lines:

 
 

With the new engine/transmission even more detail work was performed:

 

Final Before/After in the engine bay:

 

Our ZCG Exhaust system using 2.5″ piping to a stainless resonator and Magnaflow muffler with slash-cut tip. Listen to the sound in the video below!

Dyno Tuning

 

Rob dyno tuned the Rebello 3.1L engine making a stout 199hp/221tq to the wheels. Enjoy the L-series music in this extended video of Richard’s Z including dyno runs, test drive with Rob and drive-bys:

 

Suspension

 

Richard’s chassis was treated to a full suspension rebuild with new parts, bushings and a full coil-over (Koni struts with our spring rates) suspension from Techno Toy Tuning. T3 finishes the suspension in our signature color and we really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

 
 

New parts included the T3 adjustable T/C rods, T3 rear control arms, T3 front/rear strut tower bars, new ball joints, new front bushings, all new bearings and seals and ST sway bars. Richard wanted a fantastic driver that was worry-free. We replaced all of the hydraulics and front/rear suspension assemblies to match the new driveline.  All suspension was either zinc’d or powdercoated:

Rear end with T3 lower control arms and ST Sway bar:

 

ZCG Big-Brakes and CV Axles

We are proud to have several of our ZCG products on Richard’s 240z. We installed our Z Car Garage Big-Brakes (for small wheels) and also upgraded to Z Car Garage CV Axles! These products have been standard on numerous ZCG builds.

    
 

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.

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

 

We went ahead and got Richard dialed in with the ZCG big-brake kit for small wheels with parking brake and a new OEM Nissan master cylinder. More pics in the gallery!

At the rear, the OEM drums 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 130+ CV axle kits on customer cars and we are stoked with all of the positive feedback.

Panasport Wheels

 

Our ZCG Big-Brakes also look great behind Panasport wheels in our offset allowing us to run 225/50/16 tires (Bridgestone S-007a). The Z was fully aligned afterwards.

 

Interior

 

One of our favorite upgrades to the interior of an S30 is our ZCG sound deadening package. Usually found in our full-blown ZCG restorations, the result is a less tinny sound and almost Germanic-like “clunk” when you shut the doors.

 

We are really proud of the HVAC system in this Z. A vintage A/C unit was modified to work with the factory heater box and OEM controls. Our client Kurt W 3D-printed us a vent part to allow the A/C to blow cold and hard…see the video! We are working on a solution for all our customers stay tuned!

 

New, high-end carpet throughout:

 

The stock seats were replaced with Recaro Specialist in black leather, we love these seats for the S30:

 
 

Details

 

The little things are what we excel at. Exterior items include straightening and re-chroming both f/r bumpers. We also removed the 80’s style front spoiler and replaced it with the the correct 3-piece setup from our Series 1 parts stash:

 
We installed electric power steering, it is a wonderful upgrade see how effortless low-speed steering is in our video above!

 

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

Enjoying The Ride

 

In December 2020 Richard made the trek from Eureka down to Z Car Garage to pick up his restored Z. After he came back from his test drive it was quite emotional for the two Z car enthusiasts. Rob recalls…

“Richard got out of the Z and told me he had bought this Z 50 years ago that week, it’s been with him through alot of stuff and now his kids and grandkids will get to enjoy it. I looked him in the eye and said I’ll be here for their chapters, any time they need me. I’m attached to this Z now too.”

 

Richard was ecstatic. It was the reaction we live for at ZCG:

“I delivered the car to Rob and put a lot of trust in him. Nothing happens fast but what happened to my car is truly miraculous. Rob’s attention to detail is unsurpassed. It was just last December that I was able to pick up the car. It was exactly 50 years to the day that I bought the original car. It is not the Z car of yore. Rob had replaced everything. If it was bolted to the frame, all the original equipment came out. From new Recaro seats, interior upholstery replacement and sound deadening. He started up front with the radiator through new larger engine with 3 -2 barrel carburetors to tranny, exhaust system, suspension tires and wheels. It is a brand new car inside but still looks like the Ferrari I saw so many years ago.”

 

 

Richard began Enjoying the Ride in his fresh Sunshine Yellow Z back home. He sent us an e-mail of his adventures.

 “It has been a whirlwind 4 days in my life. Friday was my drive to San Jose hauling a trailer and all the while the anticipation of seeing the Z after the restoration. Saturday morning was nothing short of exhilarating. There was my little beauty, long in tooth but brought back to its original radiance. Not just radiance but purposeful modifications. What you have done with the car is truly remarkable. It is not the same car beneath that unmistakable glow.

Our visit and talk was also a highlight for me. Your exuberance is contagious. I do so love out of association. You have given me a link to my past and the wonderful times I have spent with Cheryl and my boys. So ends an odyssey that began a few years ago. I could not be happier for two reason. My car has been brought back for me to enjoy and I have made friends with an amazing man. Thank you Rob for all you have done for me.”

 

 

Richard, thank you for letting us be part of your Z car journey. We love your passion and connection to your Z. Enjoy the photo gallery and…

LONG LIVE THE Z!

Ready to Rally: Ken’s 1971 Datsun 240z

Filed under: 240z,Featured Cars and Projects,Parts,Performance
by Alvin G @ 7:28 pm on December 4, 2020

 

We met Ken W last summer when he stopped by Z Car Garage to meet Rob and have his S30 inspected. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with upgraded suspension parts and a Rebello 3L engine transformed his 1971 240Z into a fantastic sports car.

 

The Right Z

Before we dive in to the upgrades let’s take a look at how Ken got into Z cars and finally found the right one…

“When I was a junior in High School, the cool kids were driving Mustangs, Camaros, and ‘Cudas. Always different, my imagination was captured by the ’71 Datsun 240z. Being a Kansas farm boy on the lower end of the economic scale, had to settle for a ’64 Ford Fairlane 500 4-door with the 269 V-8. Knew that someday I’d own a 240z. Spent 2018 researching the 240z market. In January 2019, bought a red ’72 240z with Wilwood brakes, QA1 coil-over suspension, 17” wheels. A little rough but convinced me that owning a 240z as a daily driver, was going to make me happy.”

 

We inspected Ken’s red ’72 240z and found many problems. Rob suggested finding a chassis in better shape to make his own. After our evaluation Ken consulted with fellow S30 owner/racer Glenn C to affirm that ZCG was the right place to be. Ken was convinced that the S30 is a great rally car and began searching again, finding this green ’71 on Craigslist, near Sacramento.

“Rob gave this car his approval as a basis for the rally car that I wanted to build. ZCG is so popular that we weren’t able to get it in for the chassis upgrades before the Mother Lode 400 rally in June 2019 . The car was fine, but only fine. Yes, the brakes and suspension worked and the motor was dependable, but with the enthusiastic style of rally driving, showed they really weren’t up to the task.”

 

ZCG Big-Brakes and CV Axles

The upgrade process began, giving Ken the ability to brake on a dime, perform well and daily drive. We handed him 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 🙂

   
 

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.

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

 

We removed Ken’s brakes and installed our ZCG Big-Brake kit. The Z also received Tokico 5-way struts with Eibach springs and suspension parts from Techno Toy Tuning. New parts included adjustable T/C rods, rear control arms, new bushings, rack bushings, steering coupler, factory Nissan ball joints, new wheel bearings and more.  We really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

 

ZCG Big-brakes up front:

 

T3 T/C rods and new brake master cylinder/booster:

 

Suspension Techniques sway bars installed front and rear:

 

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

“I really the brakes. Having experienced stock brakes and the Wilwood’s (Stage 4 front and rear), was really interested to discover if the ZCG Big Brake kit was all that I’d heard about. I’m here to say that the Big Brake kit exceeded all expectations. Under hard braking, feels like I’ve just driven into a huge pool of thick super glue or that someone immediately behind me has just switched on a huge electromagnet. Undeniably shorter braking distances. Huge confidence when diving deep into corners.”

 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. Ken’s Z received set #298. We have over 100 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

Stock half shafts and control arms (L):

 
 

Before/After suspension upgrades. Not shown is the ZCG exhaust system using 2.5″ piping to a stainless resonator and Magnaflow muffler with slash-cut tip:

 

Great feedback again from Ken regarding the suspension upgrades:

“In August 2019 it went into ZCG shop for the upgrades. Let’s talk about the suspension first. My red ’72 had QA1 coil-overs and it wasn’t particularly balanced or optimized. Too soft in front, too harsh in back, little squirrely under brake or gas. By comparison the ZCG components showed care in selection, thought in design and clear goals in creation of a balanced package. The car is impressive under braking, squatting uniformly and smoothly. Under hard acceleration, it tracks straight. The CV axles are works of art and well suited to handle the Rebello motor to come.”

 

More Power

 

With braking and suspension sorted all Ken needed was power to match. Without going too wild we opted for a Rebello 3L, retaining SU induction. The 3L still leaves room for aggressive cam/Mikuni induction upgrades should he feel the need. A few pictures of the fresh motor, more in the gallery below:

 

Ken enjoys tinkering with vintage motorcycles and rallying. While running the Snowball Rally the car did really well and he had a great time but unfortunately, it was hit by a motorist (not part of the rally). We called upon our man William from William’s Auto Body to fix everything and re-spray.

 

While the motor was out, we cleaned up the engine bay. Everything came out, the bay was painted, new seals around all hoses going through the firewall. The engine got an MSA 6 to 1 header, all intake/exhaust gaskets, MSD6Al box with tach adapter, Koyo race radiator, zinc’d hardware and new alternator/starter. We  ensured that he would be able to rally wherever and whenever.

 

Backing the 3L is a 5-speed with JWT aluminum flywheel and Exedy clutch:

 

Rob dyno-tuned the Z with the stock L24 (109hp/128tq) and the 3L, now making 199hp/209tq to the wheels:

 

Enjoy the L-Series music!

 

Panasport Wheels

 

What is the perfect companion for Ken’s Z, now that it has full suspension and wicked brakes and fresh paint? Panasport wheels! We replaced the old-school slotted wheels with 16×7 Panasports and Bridgestone’s killer S-007a tire in 225/50/16.

“The Wilwood Stage 4 front brakes required a spacer to move the generic Japanese front wheels out far enough to avoid fouling the calipers. This meant running 215/45/17 tires. A drawback to the 17” wheels is that the space-saving spare can’t exceed 16” in the spare tire well.  I totally love the beautiful Panasport wheels! When I take the car to Z car meet-ups, everyone says “this car has been to ZCG, right?” The wheel and brake combo means I gained 10mm tire width and no spacers. We agreed that for rally purposes, I’d change the tires every 3 years, so Rob picked out some nice sticky ones.”

 

Rallye On!

 

Ken was smiling ear to ear and told us we built him a Z car he really enjoyed:

“The results are fabulous! My car is such a hoot to drive. Quick off the line, easy to spin the tires. Now I understand why Rob recommended the CV shafts. The car was awesome on the 2019 California Melee. Had so much fun driving the rally with my brother who flew in from Kansas. He drove it much slower than I did, so when I took my first shift, diving it deeper and deeper into the corners, accelerating harder and harder out of the corners, that I proposed establishing a safe word if he wanted me to ease off the fun.”

 

 

We have been checking in with Ken and he’s happily Enjoying The Ride. We even spotted his Z cars while cruising through the neighborhood.

 

“I’m so happy to have met Rob and provided him with a car that has ‘good bones’. Enjoyed working with ZCG. A key for me is that ZCG has been able to provide all the upgrades, in an integrated package. Didn’t want to use multiple shops and fight through finger pointing. Trust Rob and his crew, they’ve done these upgrades 100 times or more. They know what works and what doesn’t. Personally, I care more about the quality of work performed and the result, rather than shopping for the lowest price.”

 

Thank you Ken for allowing us to help you achieve your vision of the ultimate Z car. We loved working with you. Long Live The Z!

GT-R At Thunderhill

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 11:19 pm on March 9, 2011


It’s raining GT-Rs at ZCarGarage! Owner Kevin K had a blast driving his GT-R at Thunderhill recently. You might remember seeing his car at ZCG for several mods including an exhaust system, wheels/springs and a few other items. Kevin also displayed the GT-R at the SJ Auto Show in January. These awesome on-track pictures are from Gotbluemilk.

How cool does this R35 look at speed?

Kevin had an impressive list of parts installed including:
-Deatschwerks 750cc injectors
-Cobb AccessPORT, Custom tuned by HorsePower Logic
-Clear Bra by Premier Protective Films
-Downforce Carbon Fiber body kit by none other than Williams Auto Body
-Go Fast Bits blow-off valves:

Check out the AMS Catted Downpipes, compared to the OEM units:

The stock rear section of the exhaust was replaced by this beautiful HKS Legamax Exhaust:

The center section leading up to the downpipes was replaced by a GTM Challenge Race Spec non-resonated midpipe:


It looks and sounds amazing!

Kevin has great taste and chose some very sharp Volk Racing TE37 G2 wheels finished in Flat Black: 20 x 10 F, 20 x 11 R. Combined with Swift Springs and carbon fiber lower trim this GT-R looks sinister on the street and on the track!





370z Gets Down and Darker

Filed under: 370z,Performance
by Forbes @ 3:14 pm on November 12, 2009

You might remember this 370 from awhile ago when we installed a set of Berk high-flow catalytic converters as well as a Stillen exhaust system and the car put down over 300 wheel horsepower.   Well it came back last week to add a few parts to help it handle as well as it accelerates now.  We started off with the standard Eibach Springs Pro Kit and then added upper front control arms and rear lower control arms to keep the excessive camber in check.

The adjustable SPC Performance control arms allow for a perfect alignment on the track or the street.  The front arms are of a hybrid tubular design which allows for increased strength and reduced flex over the cast aluminum pieces.  They come with all the bushings pre-installed so installation is a snap, for the most part, and they are finished in a semi-gloss black which is a shop favorite.

To stiffen things up even more we also installed a set of new sway bars from Hotchkis suspension.  We have been using these for years on most of the newer Zs and Gs and are always satisfied with the decreased body roll and planted feeling that they provide in the corners.

Not wanting to leave things looking stock, the owner opted for a couple of exterior paint changes.  Now the car was sent over to Williams Autobody to have the front “fangs” and the rear exhaust surround painted in a semi-gloss black.  This is a nice and easy way for the owner to set his Z apart from the crowd (unless the ZCG 370 is around), but to take it one step further we also sent the factory “Sport” wheels out for a quality powder coating job.  What color?  You guessed it, semi-gloss black.  I think it looks awesome.  No one will be mistaking this car now.  (We put the car on our spare R35 GT-R wheels until the stockers came back)

In the end, the tasteful modifications done to this 370z will allow the owner to enjoy his car to it’s fullest, or until he comes back for more anyway….  The 370z just keeps getting better and better.

The full gallery is after the “read more” from beginning to end to show you the ride height change and such  ENJOY!!

Planted Feet: S30 Rear Suspension Upgrade and More

Filed under: 240z,Maintenance,Performance
by Forbes @ 8:40 pm on November 4, 2009

This car belongs to the one and only William of William’s Autobody fame.  The 240 came into the shop with a noisy valvetrain so we (Josh) removed the front cover and discovered that the timing chain tensioner had dismantled itself over the last few hundred miles.  Uh oh.  Normally this would result in the chain jumping a tooth or more on one of the gears which would cause terminal engine damage, we happened to get lucky.  Part replaced, Long live the L-series engine!!

Turning our focus towards the rear of the car, we have a slight overhaul in order.  What you see here are a set of T3 (Techno Toy Tuning) fully adjustable rear control arms.  These new pieces are light years ahead of the stock stamped pieces in terms of stiffness and adjustablility.  The perfect alignment is now achievable.  To accompany the control arms and their new bushings are a set of 250lbs/in springs (up from 175lbs) to firm up the rear a bit.

The new rear suspension pieces and and replaced tensioner will help our faithful painter enjoy one of his Z cars to its fullest.  ZOOM ZOOM (He has a Miata as well)  Long Live the Z!!
