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!
Our customer Randy Jaffe’s 1970 Datsun 240Z Safari Tribute is featured on the latest episode of Hoonigan Autofocus with Larry Chen. This Z is based on the original car that won the East African Safari Rallies in 1971 and 1973. Watch Randy and Larry discuss the foundation for the build and little details that remain faithful to the original. There are many other Nissans and Datsuns in Randy’s collection with more features on the way. Enjoy!
Stay tuned for a full zcarblog.com feature where we will take a closer look at our work on this cool Z.
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.
New brake master cylinder from Nissan and stock vs Big-Brakes:
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!
Everything we know. Everything we love. Everything we live for. In one letter.
The New Z Car. By now many of you have seen Nissan’s Z Proto in the media or even in person as it tours the car show circuit. On May 2, Nissan invited us to their headquarters in Tennessee to get up close and personal with the Z Proto, still very much in pre-production form. After seeing, hearing and feeling this car in person we are thoroughly stoked for the new Nissan Z. Enjoy this report from our trip, complete with photos and video.
Nissan is Back
Z car enthusiasts worldwide have been awaiting a successor to the current Z and many were satisfied when Nissan officially unveiled the Z Proto on September 16, 2020. The live-streamed event featured Alfonso Albaisa (senior vice president of global design) and Hiroshi Tamura (chief product specialist of the Z Proto) both very enthusiastic and assuring that while the Z Proto is only a development model, we will get a new Nissan Z.
Fast forward almost six months after the unveiling…Nissan debuted this commercial that gave me chills. I immediately texted Rob that Nissan is back. This brilliantly-executed advertisement was exactly what we needed and shows a direction that we are totally on board with:
https://www.youtube.com/watch?v=9kdVkUta8TI
With our New Z car anticipation growing stronger we just had to see it for ourselves, in the metal. You can imagine how happy we were when Nissan Corporate reached out to Z Car Garage and invited us to their headquarters in Franklin to spend some quality time with the Z Proto. Rob and I hopped on a plane to Tennessee…
Arriving at Nissan HQ, our hosts were Jonathan Buhler (Sr. Specialist Corporate Communications at Nissan) and industry veteran Dan Passe (Director, Corporate Communications). Both gentlemen are hardcore automotive enthusiasts (see Jonathan’s personal Datsun 240Z) that proudly wave the flag for Nissan. The kind of minds you want at a car company, and very gracious. Rob and I were in for a treat, and and we were blown away. First order of business: see the Z Proto inside Nissan HQ…
The Nissan Z Proto:
We were given the opportunity to get up close and personal with the Z Proto. To be concise, this car has a presence that simply isn’t captured in photos. A small disclaimer: the details we admired and discovered on this car may not transfer to the production car, but based on leaked photos, and as mentioned in the unveiling by Alfonso the Z Proto’s design is extremely close to what consumers will be offered. After sitting in the car and taking in its design, both Rob and I were enthralled and eager for the new Nissan Z. Let’s take a closer look…
Exterior
The familiar silhouette of the Z Proto instantly caught our eyes when we first saw it inside Nissan’s light-box room. By design, nearly every element seems to have been inspired by previous generation Z cars. Front features help take you back to Japan-only models like the 240ZG of the 1970s with “sugar-scoop” style headlights. The LED lights cast a “Z” halo:
That front grille/bumper treatment everyone seems to be split on? The square-shaped grille comes off looking awkward in pictures, but it looks totally appropriate to the car in person. Eagle eyes will note that the grille’s rectangular details carry to the interior and rear end. It works really well.
While the front end is both familiar and striking, the rear end is even more intriguing. We can’t get over the fact that Nissan put their contemporary twist on the 300ZX (Z32) taillights! Their sharp, rectangular LED elements are perfectly executed.
Nissan incredibly managed to retain the iconic Z profile while updating the body surfaces to give a much needed styling refresh. Gone are the bulbous, over-flared and over-designed features of previous generation Z cars. No chunky door handles. No weirdly-shaped headlight/taillight treatments. The Z Proto manages to be understated, with elements familiar and welcomed by Z enthusiasts. Look at that mid-body character line that evokes the S30…only here it follows an almost Coke-bottle shape with strong shoulders over the rear wheel wells. We snapped a few outdoor shots to capture the surface details. It was hard to detect the hood lines, another S30-styling throwback!
We doubt the Fairlady Z badge on the hatch will see production (it never did for US-Market Z Cars!), but we sure hope the pillar Z emblems stay, along with the “Katana” silver rails. It will be interesting to see what the aftermarket holds styling-wise with front/rear fascia’s, side skirts and general aero. We give Nissan a huge Bravo! for the design of the Z Proto. More pictures in the gallery below!
Performance
Yes, that is Rob Fuller taking a peek under the Z Proto. No, we can’t tell you what the chassis looks like or what is even under the hood. Nissan has confirmed that the new Z will use a twin-turbocharged V6 engine. That alone makes us sing Hallelujah, for boost is always better! Internet sleuths hint that the VR30DDTT engine found in the Infiniti Q50 and Q60 would be the simple choice for Nissan. Rated at 300 or 400hp in those cars, we have dyno-tuned many with simple bolt-ons yielding 100hp+ over stock quite easily.
Rob and I were given permission to row through the gears. Yes the Z Proto has a real 6-speed manual transmission and the New Z will also offer one. No word on those sexy brakes and tire letters, but with Twin-turbos and a manual transmission sign us up!
Interior
Both Rob and I were impressed and satisfied with the exterior of the Z Proto, and the interior also did not disappoint. Remember, this is a no-frills sportscar, and it shows in the material choices, switchgear and overall design theme.
That being said, there is a great mix of digital and analog elements on the dash. We loved the large digital instrument cluster, central touchscreen and nostalgic triple gauge pods. Thanks to Jonathan for powering up the car so we could see all the digital features, a real treat not given to most journalists! He was eager to point out a few Nissan-placed Easter Eggs too…
Easter Eggs
Jonathan drew our attention to a few not-so-easy to catch details like the “Z” logo on headlights and “since 1969” text on hatch window. Dan Passe chimed in with the “Z” cut lines at the union of the A pillar, hood and leading edge of door (more of an intentional design detail). Then there’s the fairly gratuitous nods to the 370z, and 1969 240z on the dash display and center stack. Note radio station with song title and time 🙂
The Z Proto is a home run. This is a sports car Nissan should be proud of. Well done! We can’t wait to get the New Z at the shop. For an automaker to build something this special is risky but also speaks volumes as to how they value our input. Enthusiast’s input! It’s a bold move especially in this climate where sport cars are relying on electric powerplants and automatic transmissions. “The Z Proto represents a commitment to our fans, to our heritage, and staying true to Nissan’s DNA.” We couldn’t agree more after seeing it in person. Long Live The Z!
We couldn’t leave you with just pictures so here is an extended video of our personal visit to Nissan HQ to see the Z Proto. We were fortunate to not only see it, but take it for a spin around the campus and really absorb all of the design details…enjoy!
Our visit with Nissan only begun with the Z Proto. Before heading to our next destination we stopped by legendary Z shop Crawford Z Car Service in downtown Nashville. Owner Doug Stewart is an accomplished Z-car racer and you night remember the creator of the Crawford intake plenum for Nissan’s 350z VQ engine.
Nissan Heritage Collection
A visit to the Nissan Heritage collection was next on our tour. Nissan’s production plants in Smyrna and Dechard and HQ in Franklin, TN are pretty well-known but the Heritage Collection is hidden inside the Lane Motor Museum in Nashville. The museum itself is open to the general public and it’s a must see:
Undeground and beyond closed doors, we entered paradise. Both Jonathan and Dan have dedicated their time-on a volunteer basis to preserve, maintain and promote this vintage Nissan/Datsun collection. Without them it wouldn’t survive, and in part they rely on enthusiasts (like Randy Jaffe) to help carry the torch. These are cars that would have been scrapped by Nissan or left outside to rust. Rob and I were literally in heaven. So much history in one place with wicked metal at every turn. (Below) The actual Black Gold TV commercial 280ZX and 2021 TV commercial Z31 that actress Brie Larson was in:
Everywhere we looked there were”JOB #1″ vehicles, race cars, movie/commercial cars and even concept cars…we could have spent the night with the collection. What sets this collection apart from others is that all cars are accessible and drivable (or meant to be driven). No roped-off cars or locked doors. I even got to sit in the race car!
Forgotten concept cars. Some were old. Some were shockingly recent(See that Q50 Eau Rouge?!)
This 1200 truck needed some attention and this was recently shipped from the Heritage Collection to ZCG for some love!
There were way too many cool cars to mention so please check out the photo gallery and video below!
Here is a video of our visit to the Nissan Heritage Collection, enjoy!
Datsun Roadsters
The Datsun Sports (310/311) or affectionately known as “Datsun Roadsters” are some of our favorite models. We were both surprised and happy to find that Jonathan and Dan had recently rescued a few from a barn. All of the cars they recovered were interestingly “2000” models from 1968 to 1980. Thanks to their efforts these gems will be restored and driven!
Thank You
We thank Nissan, Dan Passe and Jonathan Buhler for the opportunity to visit. The Z Proto is a winner and we were throughly impressed with the Heritage Collection and your efforts to keep it alive. Looking forward to working with you in the future, LONG LIVE THE Z!
