The 2018 Japanese Classic Car Show was held on September 15, in Long Beach, CA. This is the original vintage Japanese-car event in SoCal and in its 14th year, JCCS has grown incredibly–over 430 cars covered the lawn of Marina Green Park. The vehicles themselves remained a fantastic blend of stock, modified and restored. This is the most important show for Japanese cars, and the Z Car Garage crew keeps coming back every year to soak up the sun, see old friends and drool over some spectacular vintage builds.
ZCG Displays Two Z Cars!
Z Car Garage displayed two customer cars at the show: Randy Jaffe’s 1970 Datsun 240z and James Stevens’ 1972 Datsun 240z. Randy’s Z was completed in time to be our booth car. This Series 1 S30 started as a project car 4-years ago with paint/bodywork performed by Bryson Richards of Classic Livery. The Z was shipped to us from Georgia for finishing Randy’s vision of a wild show/go race car:
Inspiration for the Jagermeister livery came from Randy’s obsession with Porsche, and the Max Moritz Racing Porsche 934.
We will take an in-depth look at this Z in separate post, but here are a few key details. Providing room for the 275/315-width tires is an authentic Pandem Rocketbunny aero kit. Randy channeled his passion for racing into this build and the chassis is virtually identical to his #46 BRE Datsun 240z, using zinc’d DP Racing suspension parts. The engine is a big displacement L-series running 13:5:1 compression, triple-Mikuni ph44s, a Fujitsubo header and glorious BRE-style exhaust. Running gear includes a close-ratio ZX transmission, OS Giken LSD for the 4.11 R180, our ZCG CV Axles and ZCG Big-Brake Kit (race version).
We are happy to report that Randy’s Z won 1st place, Best 240z in a class filled with incredible Z cars!
James’s 1972 S30 was displayed with fellow Z car owners in the show. At the heart of this beast is a turbocharged L-series managed by Haltech. Chassis upgrades include custom full-length subframe connectors, our ZCG CV Axles and Big-Brake Kit (328mm) behind Volk TE37V wheels.
A stack instrument cluster was integrated into the gauge pod, viewed from leather Recaro Pole Position seats. This Z has a very unique sound. We recently tuned it on E85, dyno results and videos coming soon!
We are very happy for James as he won the award for Best of JC Speed!
Stay tuned for in-depth reports on both of these Z cars coming to zcarblog.com.
Showtime!
Our friend and talented racer Troy Ermish transported both of our Z cars (and his 510) down to Long Beach Friday afternoon. Below is a video of the Z’s loading from the shop:
We unloaded early Saturday morning from the expansive parking lot near the new venue in Marina Green Park. Immediately we could tell this location was larger and more vendor-friendly than The Queen Mary of past shows. Our booth was situated in a great spot, at the mid-point of the show with our neighbors from OS Giken. …[read more]
For #throwbackthursday we take a look at Rob Fuller’s 1970 Datsun 240z. This Series 1 S30 gained notoriety 15 years ago when it was powered by an RB25DET drivetrain. We had many good memories with the RB-configuration and like all Datsuns, this one has a great story behind it.
In 1997, Rob spotted a ’70 240Z sitting in a driveway while driving down a back road in Georgia. He soon learned that the owner had the Z for a really long time and it hadn’t been running for years. Unable to afford the owner’s price, Rob offered to wash and detail the car, as well as bringing a car cover to protect it until he had funds for towing. Eventually a deal was made with the seller, and Rob towed it home to start working on it. In 1998 he started his first job working at Z Service Unlimited in Atlanta when the recently acquired Z overheated and failed.
Rob and the 1970 240z at Z Service Unlimited in GA, ~1997. (Right) Turbo Tom’s EFI turbocharged L-Series build, still at the shop today:
A customer’s ’71 240Z had rolled-over and Rob swapped it’s 2.8L/5-speed/R200 diff into his Z. He enjoyed driving the Z all around Georgia before relocating to Northern California where he was offered a job at a local Z shop. Once the 240 was shipped over, Rob saved up money for yet another engine transplant, this time a 3.1L stroker with SUs. He attended many track days at Thunderhill and Laguna Seca with the setup. In 2001, the car was painted ’70 Mopar Go Green by William’s Auto Body:
In 2004, Rob opened Z Car Garage and started building a turbocharged L-series (utilizing Turbo Tom parts) for his Z. After completing his SR20DET-powered Datsun 510 he was inspired to have the same modern powerplant for GO GA Z. The turbocharged, inline-6 from the Nissan R33 Skyline was a logical choice. The swap was completed by July 2005.
A quick breakdown of the build: T3/T4 turbo, Nismo 740cc injectors, GReddy intake manifold, custom Z Car Garage front-mount intercooler, C&R radiator, JWT aluminum flywheel and heavy-duty clutch. Ford Lightning MAF, a Z32 TT fuel pump DEFI gauges. Suspension consisted of full Ground Control parts with 5-way adjustable Tokicos, custom 993 Porsche brakes behind 16×7 Panasport wheels wrapped in 225/50/16 Kumho Victor Racer V700 tires.
How did it perform? At 19 psi, the Z put down 440 whp and 380 lb-ft of torque at the wheels on the ZCG dyno. All while making the most intoxicating sounds. Enjoy this compilation I made of the Z in action, speakers up!
We enjoyed driving the Z to car shows/events including long trips to JCCS (2006) and the Mt. Shasta All-Datsun Meet.
GO GA Z even got some media exposure (before the days of Instagram and Facebook!) Below: Sport Compact Car Magazine, Lighting Auto (JDM), and Turbo Magazine
So where is the Z now? In 2009 the RB25DET was removed and built up to RB28 spec for installation into Gary’s Behemoth.
Gary would later decide to run the legendary OS Giken TC24B1Z in his Z, making it the world’s first LHD OS Giken TC24B1Z powered S30. Rob’s Z was the test mule for the TC24, a little known fact. Here it is on the dyno:
The RB28 sits on display in the front office at ZCG, while the GO GA Z chassis is still being utilized for TC24 development.
We hope you enjoyed our trip down memory lane with Rob’s RB-powered Z. I loved this car so much I built a 1/24th scale model of it. Please read on to learn about the model and see more pictures. LONG LIVE THE Z!
About The Model
One of my hobbies is 1/24 scale model car building. In the past few years I’ve focused on building scale replicas of friend’s personal cars. Rob’s 1970 240z holds a special place in my Z heart and I thought it would be a nice challenge to make a model faithful to the real car.
I made sure the engine bay had the entire RB25DET drivetrain visible with Greddy intake manifold, injectors, turbo and FMIC plumbing, BOVs, and that Interstate battery. On the outside I used Go Green paint for the body, Porsche Big Red calipers with cross-drilled rotors, Panasport-type wheels, and a photo-reduced license plate that reads ” GO GA Z”. The interior even has DEFI gauges, a MOMO steering wheel and Recaro seats…just like the real thing! Enjoy the pictures and stop by the shop to see the model in its display case, but please do not touch it 🙂
When we last saw Erich C he visited Z Car Garage for some sorting on his 1973 Datsun 240z, reported in our blog post here. The Z was fresh from a restoration by fellow racer and Datsun 510 specialist Troy Ermish, sporting a Rebello 3L with triple Mikuni carbs and many hot rod parts:
Erich’s Z made an impressive 261hp to the wheels on our dyno and he felt the need to have brakes to match that power. We recently installed our ZCG Big-Brakes for small wheels on Glenn’s Fairlady and his review was positive:
“WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car”
As Glenn 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, etc. After Erich drove Glenn’s Fairlady with the Big-Brakes, he was a believer. Erich returned to ZCG to have the brake kit installed on his S30.
The existing new Wilwood brake setup was removed and replaced with the ZCG Big-Brake kit at all 4 corners.
Up front:
Rear:
Erich was really stoked about the parking brake assembly, and now he has a fully functioning parking brake, utilizing the factory hand brake lever and linkage. This was another key request for our customers when creating the Big-Brakes.
A few more detail shots of the brakes:
And of course, the brakes fit easily under Erich’s sexy 15×8 zero offset Watanabe wheels:
For great stopping power, feel and bolt-in convenience, look no further than ZCG Big-Brakes for small wheels! Stay tuned as we bring you more Z’s getting the kit installed, joining our customers Frank, Sam, and Glenn. Erich is really happy with the brakes and we loved working on his Z, Enjoy The Ride!
This 1972 Nissan 240Z-L however is “the list” car for Glenn that started his Datsun passion. Glenn has owned it for several years, enjoying it as a back-road burner on the street and rallye events.
Find out more about the story behind this right-hand-drive survivor over on Petrolicious and also watch this great video:
We’ve known Glenn for many years and we actually tuned his Fairlady back in 2012. The 3L stroker produced one of the highest dyno numbers we had seen!
Big Brakes for Glenn’s S30
The Z clearly had more than enough power, but braking was always something Glenn wanted to improve and once he heard about our latest Big-Brake Kit for small wheels he became a believer after test driving them. Rather than tell you how we feel about this product, let’s hear Glenn’s experience.
Throughout my years of Z car ownership, I have run a variety of brake setups. My Z cars have seen everything from restored OEM Sumitomos, Toyota 4×4’s, trick Wilwood setups, even frankenstein’d Baer calipers. There is no doubt that it has been one area that I have never been completely satisfied with. Over time, after many years and attempts to find the ‘perfect’ setup, I had given up and just settled for what I had.
The most important aspect to me when it comes to braking on a street driven car is feel. Yes, stopping power is extremely important, but also is not that difficult to achieve on an early Z car that is naturally light to begin with. Feel, however, is something that has always managed to escape me. On my vintage 240z race car, we use multiple master cylinders, swap them in and out, fiddle with our brake proportioning valves, fine tuning them to fit our driving style and preference. We are trying to find that “racer’s edge.” In all honesty, when it comes to a street car, I want nothing to do with all that.
Wheel sizing and style was also extremely important to me. I love old school wheels and the sizes they came in. I needed a brake caliper that would fit under my 15” Watanabe RS wheels without having to shave or drastically modify my setup. If it was not for being in love with these wheels, I would have opted for Z Car Garage’s larger big brake kit.
A few words about our latest big-brake kit solution. Our successful, larger ZCG BBK utilizes 328mm rotors and 4-piston calipers requiring a 16″ or 17″ wheel. This kit was made with our friends Tyler and Eric from Stoptech over ten years ago. Recently our customers asked us to make a BBK for smaller wheels so even a guy running 14″ vintage 5-slots slots could brake like a modern sports car. Typical big-brake kits use a 4-piston setup up front and a ZX in back; Proportioning is hard to get right, varying from car to car. We wanted a brake system that suited the car and totally bolted in, no M/C change, no proportioning valve, no booster change.
Working with Stoptech again, we developed this smaller BBK as a direct bolt-in solution for the 1970 to 1978 S30 Z cars. We’ve been with Stoptech since the beginning and love their products. We aim to release this product to the masses once our local installs are completed. Let’s get back to Glenn and hear his initial impressions of the big-brake kit:
Rob informed me he was working up a solution and he wanted me to be test the brake kit. Rob promised three things – they would brake amazing, they would fit under my 15” Watanabes, and they would feel as if they belonged on the car. Did I doubt it at first? Sure, a little. However, I also knew that the fit and finish of all products that came out of ZCG were top notch, and that Rob thoroughly tested all his products against his own standards. Which I’m sure everyone knows, are extremely high.
In preparation for the Monterey Historics last year, I had brought the Z race car to the shop for dyno time. Rob gave me the keys to his Butters Z and said “Go drive it.” Under 14″ wheels sat his brand new ZCG brake kit. I gladly accepted and took the car for a ride.
WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car, and these were on a car with stock suspension, tires and probably cruddy tires! I told Rob, “sign me up!”
Glenn wanted to run the brake kit on his Fairlady and we happily obliged. He had also been gearing up for a road rallye so the braking system would be throughly used. You can see his Z (top left) along with his buddy Erich C’s S30 (top right, also getting a ZCG BBK!):
Then came the day Rob called me up and said they were ready to rock and roll. Lucky for me, I was just about to head out on the 1000-mile Coastal Range Rally! The kit came with beautifully anodized front and rear calipers, hats, rotors, brakes lines, reversible brackets (for early and later Z offsets), and a factory ⅞” master cylinder. Read that again… Yes, a proportioning valve was left out from that list! The brakes were a straight bolt on and ZCG did all the math to get both the master cylinder size and piston sizes correct. We brought the car in for install and within a day the car was ready to rock.
Glenn’s 240z now had 4-wheel disc brakes ready to tackle the street and rallye:
And of course, the brakes fit beautifully under the 15″ Watts. Kane approved, and Glenn was stoked:
I could hardly wait to jump in the seat of the car and take it for a spin. The brakes were now on a car with suspension, tire, power, and a proper alignment. It was everything I had remembered from driving the Butters Z and MORE. The brakes performed flawlessly on the Coastal Range Rally, taking abuse from California’s most challenging roads:
Attention to detail goes a long way. This is exactly what these brakes delivered, and what continues to be delivered by ZCG.
LONG LIVE THE Z!
We are happy to report that Glenn is still braking late and still braking deep all while Enjoy The Ride! You can find him carving through the Santa Cruz Mountains:
Big thanks to Glenn for letting us work on your Fairlady! We also thank Eric and Tyler from Stoptech for supporting us and our precious Z cars!
Z Car Garage is proud to offer a CV axle conversion kit for your Datsun S30 and 510. For years we have used aftermarket CV axles that utilize an aluminum adapter prone to loosening up over time. Despite efforts to keep things tight (Loctite, hardware changes) we had to keep an eye on them. We developed a better solution that eliminates the need for aluminum adapters and remains 100% bolt-in like a factory half-shaft.
Designed and manufactured locally with KAD Models, the ZCG CV axle kit works in both R180 and R200 configurations.
These are the beefiest CV axles on the market. They have been tested on the track by our vintage racing customers and also in high hp* street cars (powershifting, clutch dumps, etc.). Each axle has a serial # for peace of mind:
The CV axle kit is available now from ZCG for 1595.00 + freight and they come with everything you need to install on your car. Contact us at 408-452-0350 or send Rob an e-mail rob@zcargarage.com to purchase. Installation is just like doing a half-shaft: there is even a marking that shows you where to line up bolts and special hardware:
The ZCG CV Axles in action
The video below demonstrates the “looseness” associated with aftermarket CV axles that use adapters compared to the ZCG axles without adapters. Several customer race/street cars running our CV axles are also shown. Enjoy!
S30 and 510s running the ZCG CV axles
Randy Jaffe’s #46 BRE Datsun 240z received the very first set of ZCG CV axles: Serial # S30-000240!
Race car driver and restoration specialist Jim Froula of Racecraft is running ZCG axles in several of his cars:
Set #246 – installed May 2018 on the “Harry Stewart #52” Datsun 510:
Set #247 – installed April 2018 on the 260z
Set #248 – will be installed on Adam Carolla’s “Greg Sorrentino #90” Datsun 510. We are pleased to report that Jim will also be installing a set on his “George Alderman #32” 300ZX! The ZCG CV axles are also perfect for high hp street cars. The following customer cars are all running our CV axles now:
Frank B’s fuel-injected, 6-speed stroker L-series:
Gary’s 430whp LS3-powered 280z:
Scott W’s EFI stroker L-series:
James S’ L28ET:
Finally, Gary’s “Behemoth” OS Giken TC24B1Z powered S30:
Technical Information:
The Z Car Garage axles were designed to help remove much of the backlash aka clunk seen in many older vehicles. Modern technology has given us the ability to create a set of axles to exacting standards. We started with a high quality set of CV joints that were found to be the most consistent in both major and minor spline diameters. We then began to design the axle itself to share the same tight tolerances. We are holding a +/- .01mm diametric tolerance on both the inner and outer spline diameters. This gives us the feeling of direct connection between differential and wheel. The axle shaft major diameter was increased to 28MM to give owners a bit of added comfort in knowing the main shafts are stout. Once the axles are splined they are then heat treated to obtain the desired harness. After heat treat the axles are then nickel plated to add corrosion resistance. The inner and outer flanges are made from 316 stainless steel and mate to the CV joints with tapered alignment surfaces to ensure concentricity is maintained throughout the axle thus reducing vibration. The inner flange attaches to the stock R series differential utilizing the Nissan factory hardware. The outer flange attaches to the driven stub with bolts specifically designed and manufactured for the Z Car Garage axle installation kit. These bolts are manufactured to grade 8. All ZCG axles are manufactured locally which helps us maintain the fitment and quality we require.
Materials
Axles : Hardened AISI/SAE 4340 Alloy Steel, 4340 is a nickel-chromium-molybdenum alloy steel
Drive flanges: 316 stainless steel, Type 316 steel is an austenitic chromium-nickel stainless steel
Outer Flange Bolts: Hardened 4140 Alloy Steel , AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents
