The iconic, 1976 IMSA GTU Championship-winning Transcendental Racing Z is at Z Car Garage! This early 1970 production 240Z has an exciting history battling against factory-backed teams with names like Jack Scoville, Brad Frisselle and John Morton behind the wheel.
The chassis was also highly-developed by a team of All-Stars including Joe Cavaglieri (Crew Chief), John Knepp (engine), Trevor Harris, Mac Tilton (suspension) and Yoshi Suzuka (chassis, roll cage and body). Current owner Randy Jaffe has commissioned Z Car Garage to bring this Z back to period livery, refresh the chassis and drivetrain components, and re-assemble the interior before traveling to its new home in Atlanta.
The Z came with many spares, period photos and even original molds for the bodywork!
Getting the livery sorted has begun, with a proper “Frisselle” windshield banner (left) based on period photographs (right)
Here is a short video of the Z as it arrived to the shop early this week. Dyno testing with video coming soon!
Always Meet Your Heroes
The “Frisselle” car captivated us for many years. We watched it race locally and and eventually shared track time with previous owner David Martin (RIP) at major historic events. (Below, Left) David Martin and Rob Fuller (#49 Joel Anderson car) in the Corkscrew and (Right) Rob with David and Brad Frisselle at the RMMR 2018.
You can imagine how excited we are to have this iconic race car at Z Car Garage. Big thanks to Randy for always believing in us. More photos from my brief visit:
Enjoy these videos we’ve captured over the years racing with David Martin piloting the Transcendental Racing 240z:
In a moment of sheer happiness, Rob Fuller can be seen driving the #47 Brad Frisselle Z through the paddock back in 2015!
A David Vs. Goliath History
Ever wonder about the history behind this famous 1976 IMSA-GTU Championship-winning 240z? Check out www.my240z.com. Our friend Glenn Chiou created this website to document the racing provenance for previous owner David Martin (RIP):
Glenn’s impressive knowledge of historic Nissan/Datsun racing is bolstered by hundreds of scanned photos, some never seen before along with stories from ex-drivers Brad Frisselle, Jack Scoville and John Morton. We are even given new insight on the R&D effort that went into the Frisselle car making it by far, “the best race engineered 240z in its period”.

We love to see our parts installed and used on client’s cars. Race car driver, restorer and Datsun Historian Glenn Chiou is running our ZCG CV Axles in this IMSA GTU 260z race car!
Glenn is preparing for the upcoming Rolex Monterey Motorsports Reunion event at Laguna Seca. A half shaft failure is not something he wanted to worry about while racing so he replaced them with ZCG CV Axles. Glenn installed set #367 himself with ease:
The Different Drummer Z
Glenn Chiou is our client, fellow racer and friend. He was one of the first to run our Z Car Garage Big-Brakes on his RHD 240Z and actively vintage races both 510 and Z cars. You may have seen Glenn’s FAR Performance 240Z in VIPS Restaurant livery as raced in the 70’s by Loren St. Lawrence. Glenn restored this race car himself and it is now going back to Bay Area Datsun Dealers livery as raced by FAR Performance privateer Walt Maas.
Glenn’s got a passion for re-telling the stories of legendary privateer Z car racers and his current restoration project is the Different Drummer Racing Z raced by Greg Sorrentino. This is a really cool race car with great history and build details behind it.
Chassis # RLS30-000024 is a July 1973 pre-production Datsun 260Z chassis that was sold by the factory for one dollar in 1975 to Different Drummer Racing, owned by Greg Sorrentino of Troy, Michigan. It was one of the very first Datsun 260Z chassis and was built by the legendary American fabricator, Ron Fournier. This Z car has been consistently raced for the last 40+ years in IMSA GTU, SCCA Trans-Am, and C-Production/GT-2 classes.
In 1975, the Datsun Competition Department agreed to support Greg Sorrentino’s IMSA GTU racing efforts by providing him a pre-production Datsun 260Z. Once in Sorrentino’s hands, it was left to his all-star lineup of builders to help him build a frighteningly fast IMSA GTU car:
Chassis preparation was to the skilled hands of legendary metal fabricator, Ron Fournier
Suspension duties were left to Mac Tilton
John Knepp of Electramotive Engineering built the motors for Different Drummer Racing

You can read more about the official history on this Z as documented by Glenn here:
As usual, Glenn’s painstaking efforts and diligence result in a faithful restoration…where parts are not available he has gone to extraordinary lengths to re-create pieces from historical photos…all from his garage at home.
Thanks for your support Glenn! We we will be rooting for you at the Monterey event!

Return of the #46 BRE Datsun 240Z!
The BRE #46 Z is back from paint by our man William and it is finally getting the hand-painted livery applied at the shop as I write this. You may recall that the Z was flipped on to its roof with John Morton at the wheel racing at the 2019 Classic 24hr race at Daytona International Speedway
The Z will be re-assembled, dyno tuned and tested in a few weeks at Sonoma with our hero John Morton and Rob Fuller! Super amped to see #46 back in fighting form and very happy for owner Randy Jaffe. Check our IG story to see the livery being applied by hand, this is a lost art and incredible to watch.
1970 Salt Flat Racer Datsun 240z
This historically significant 1970 Datsun 240z was built by a team of Nissan employees to compete at Bonneville in the F/GT class. In 1976 their efforts resulted in a new land speed record of 166.037 mph, which stood unbroken until 1985. This Z resided in the Nissan Museum and is now in the care of Randy Jaffe. Lots of neat details the Z 432R seats and G-nose. More to come! Big thanks to Randy and Nissan for letting us bring this Z back to life. We just finished the exhaust and dyno tuning,
One of many Z32s we are working on, Steve’s will get a full report soon as well as the Stillen SMZ:
Jim’s 1971 Datsun 240z returned for a Rebello 3.2L with triple-Mikuni carbs on a Harada intake and CD009a 6-speed transmission:

LONG LIVE THE Z! Check out our Instagram story for more updates!
Randy Jaffe is an avid car guy and Datsun enthusiast. Beyond his fanatic attention to detail and love for Nissan racing he’s excessive–in the best way possible and we love him for it. Several years ago we teamed up with Randy to turn his BRE Datsun 240z show car into a competitive vintage road-race car.
He was impressed with our work on the BRE Z and told us about another Z project that he was working on but stalled out in Atlanta. We decided it was time to finish this ultimate track/street car with a healthy dose of his personality. The highlight of this Series 1 240z is a full Rocketbunny body kit with plenty of Z Car Garage touches. Let’s take a closer look at the build:
Origins
The creation of the Rocketbunny Z changed courses many times as the build evolved, as Randy recalls:
“I wanted to build a series 1 Radical fun Street car with a completely different look. We started off thinking we would do conventional flares and conventional displacement for a 240 Z. Then my painter Bryson was doing the bodywork and had just installed a Rocketbunny kit on a 350Z and asked me to take a look at that particular body kit. I knew of the first one completed by Sung Kang and I think it was the second or third kit to come to the country when we ordered it from Japan directly.”
“The paint color which originally was going to be Porsche’s lava orange evolved because of Michael Eberhardt to Porsche‘s late 60s color called Tangerine. Tangerine painted with a white sub-coat pops where Helen Keller could see the color! Since I am color blind, the brighter the color the better I can see it. Bryson welded an amazing full roll cage as I decided to create the car as a street and track beast.”
The body was amazingly painted and caged by Bryson of Classic Livery of Atlanta. They are known for many high-end commissions including several RWB Porsche’s for Akira Nakai. Randy’s transporter trekked from Atlanta to drop off this gorgeous chassis at ZCG and our work began.
Assembly Required: Race Chassis Prep
The chassis was temporarily mounted on rollers while we prepped suspension pieces. Following the “race-car for the street” theme, we re-created the entire front and rear BRE 240z suspension setup. Everything that the #46 race car has is on this street car from DP racing front/rear struts, koni shocks, identical spring rates, sway bar, adjustable end links, plated finish…all of it. More pictures in the gallery below!
Front and rear:
Z Car Garage Big-Brakes
There are two versions of our ZCG Big Brakes and the only three “racing” setups on are on the BRE car, Alex’s Hako and the Rocketbunny Z:
Stay tuned for our latest big-brake upgrade from the minds of ZCG and Stoptech!
Back to the chassis, the entire hydraulic system was installed starting with freshly plated lines.

Z Car Garage CV Axles
Z Car Garage is proud to offer a CV axle conversion kit for Datsun S30 and 510 cars. We run these on our race cars and the Rocketbunny Z also got a set.
Helping put the power down effectively is an OS Giken limited-slip R180 diff properly set up in-house by Joshua Corwin.
Wheels Make The Car
The biggest hurdle on this car was wheel choice. Wheels can make or break the car and they had to befit the “KAMIKAZ” nickname. There was no way we would have a car with massive flares and not use every single square inch of real estate available to fill with wheel and tire.
We sourced some Panasport C8 centers and began a custom build with MemoryFab who was instrumental in helping us with fitment/barrel sizing. Up front are 17×10 with a 275/35/17 tire and 17×12 rear with 335/35/17 tire (NT-01R). At the time there were no other RB cars running a 335 in back! .
We spent many hours making the kit fit around these wheels/tires so there was no rubbing:
Everyone was pleased with wheel choice for KAMIKAZ, especially Randy:
“I had already ordered and received a set of Watanabe wheels from Japan however they would not work with the rocket bunny kit so when I sent the car to Rob Fuller at Z car garage he did his magic and created a set of custom wheels using a set of Panasport racing C8 NOS wheels. 10 inch wheels on the front 12 inch wheels on the back by 17s gives the car and unreal stance.”
Race Engine
We had Rebello build a nasty 3.2L for the Z running triple-Mikuni’s, 12:5:1 compression (110 leaded fuel) backed by a 280zx 5-speed. Randy gave us a blank canvas to assemble the entire car but ZCG touches really shine in the engine bay.
“I basically wanted my 46Z race car for the street and asked Rob Fuller to further tap into his magic box so we built a 3.2 race motor full race suspension and the whole 9 yards! Rob and his guys built an amazing car using special finishes on some of the metal work under the hood and the car is just insane to drive.”
Here are a few pictures of the assembly with many more in the gallery. Aluminum flywheel with twin-plate setup and comp oil pan just like BRE car:
Triple Mikuni induction:
Engine going in and detail work beginning. We re-created the cooling system from the BRE car and ran all of the chassis wiring.
The catch can, radiator and Datsun roadster overflow are all period parts that BRE used and duplicated for the Rocketbunny:
Interior
With drivetrain and chassis sorted we moved to the interior. Continuing the race car theme is a stripped (but pretty) body-color interior with that beautiful roll cage from Bryson.
The dash was covered in Alcantara. We installed and wired it up with period gauges. All switch gear similar to the BRE car:

Enter the JGRBOMB
This was our quickest build to date so we could make a debut at the 2018 Japanese Classic Car Show in Long Beach, CA. The night before our roadtrip down to SoCal we applied a Jagermeister livery to the car. Randy’s inspiration came from his obsession with Porsche, and the Max Moritz Racing Porsche 934:
“I love race liveries and told the guys at the car garage I wanted to do the Jagermeister racing package on this car and they were not really hip to it but Bryson and I discussed it several times and we both thought it would take the car to the next level. However I stuck with my gut and flew out to San Jose with the livery kit a few days before JCCS and after the first hood decal Rob and his guys were scratching their head thinking hmmm – This may not be a bad idea LOL.”
Rob and I finished applying the decals late in the night before going to Long Beach and we received a lot of positive feedback at that show and then the car came back to ZCon in Atlanta and won a Gold Cup award. The car was also shown at SEMA in 2018 where again the car received an immense amount of positive feedback.”
Indeed, the livery on the Rocketbunny (KAMIKAZ) Z looked fantastic and Randy eventually affixed the JGRBOMB license plate to match. We are happy to report that while at JCCS Randy’s Z won 1st place, Best 240z in a class filled with incredible Z cars!
It was also well-received at Z Con and the SEMA show (thanks to Gary and Braille!). That’s BRE front-man Peter Brock and the designer of the Rocketbunny body kit, Kei Miura both signing the Z:
That BRE Exhaust
We wanted to do a BRE exhaust so we used the Fujitsubo headers and a straight twin-exit with megaphones exactly like the BRE original set up, Randy notes the white color:
“Of course BRE had theirs painted yellow from day one and still are but I wanted to do the rocket bunny exhaust megaphones in white to play off the livery. Many vintage race cars have white headers and exhaust so it made sense to me. So the audio level is the same as the 46Z and will wake up the dead.”
How does it sound? Check out this short video with a dyno run, enjoy!
Details
It would take multiple blog posts to cover all the special details throughout this build. Some highlights include fully polishing all trim pieces like quarters, drip rails, etc. Re-keying locks. Even the mirror was done to Randy’s liking.
Things like the differential temperature gauge behind the old gas fill door have a purpose and pay homage to the Datsun vintage race cars. Contrastingly, there are small modern updates like vintage H4 headlights retrofitted with HID units.
We asked Randy what’s it like to drive:
“To me there’s no difference in driving this and the 46Z it’s almost the same build except more rubber on this one!”
To us that is a great compliment because we set out to finish Randy’s vision of the ultimate street/track BRE-flavored Z.
“I find myself several nights a week just walking around the car in my shop and admiring the build that Rob, Josh and the crew at Z Car Garage created.”
We thank Randy for letting us be creative on this Z and it’s been rewarding to see his taste reflected in other builds. This was a fun project and we enjoyed every moment of it. Browse the extensive photo gallery and LONG LIVE THE Z!
