Race car driver, restorer and Datsun Historian Glenn Chiou has just listed his IMSA GTU 260z race car on Bring a Trailer. The Z features our ZCG CV Axles and dyno tuning. This is a rare opportunity to own a fully-restored, competitive vintage race car, so spread the word and bid with confidence!
We have been fortunate to race alongside Glenn and the Different Drummer Racing 260Z at several high-profile events. See it in action in our race reports from the Velocity Invitational at Weathertech Raceway Laguna Seca.
We are huge fans of the 1990-1996 Nissan 300ZX and this “Stillen GTZ” example is a unicorn among Z32s. In the early 90’s the GTZ was a limited run, special edition 300ZX Twin Turbo produced by Steve Millen Sportparts Inc. Only 6 GTZs were built in the series, and our client Mike B owns #6 finished in Diamond Black Pearl Metallic. Z Car Garage performed a mechanical refresh with dyno tuning to get it back in fighting form.

Steve Millen took Nissan’s World Class Sports Car and transformed it into the GTZ. Suspension, engine, transmission and aerodynamic upgrades used in developing this special 300ZX Twin Turbo could be found in Stillen’s performance catalog:
GTZ-specific parts included 17″ Billet Wheels…designed by Steve Millen and Elite wheels allowing 275mm-width tires:
Aerodynamics package highlights included the LeMans-inspired GTZ Rear Wing and GTZ turbo front spoiler that directed air into side-mounted intercoolers. Also shown are the vented front/rear fenders and louvered front panel:
Optional GTZ single tip exhaust system, fitting through GTZ Rear Valance opening. Performance upgrades included Brembo front brake calipers, EVC boost controller, HKS Boost and exhaust gas temp gauges. Catalog scans courtesy of Z32 enthusiast Jay S:
The GTZ received accolades from the press, with an orange example gracing the cover of Road & Track Magazine. Their April 1991 issue featured and extensive review of the car:
“It’s and absolute carnival ride to tip into the throttle, hear those twin turbos spool up and hang on as the GTZ reels in the horizon…a tractable, smooth road car that performs, handles and feels like a race car”
Motorweek put the Stillen GTZ up against a tuned Mazda RX-7 of the same area in their wonderful road test video, you can see it HERE. The GTZ is not to be confiused with the SMZ which was a special edition of the 300ZX that was produced in collaboration with Nissan to celebrate 25 years of the Z car.
Mike’s Z32 Story
Before we get into the mechaincal work let’s hear from Mike and how he acquired his 1991 Stillen GTZ…
“I was working in Phoenix during most of the 90’s in advertising and design for major automotive brands. My job was so stressful but at the beginning and end of each day I had a 30-45 minute drive home. I was driving a 1964 Triumph TR4 at the time and also a 1991 Crown Victoria Police Interceptor. I wanted a 300 ZX TT in black and then I would add all of the body stuff like wings and front valence etc later. Saw the ad for a Stillen GTZ in Autoweek magazine and bought it in 1994 with about 7,000 miles on it. It was like brand new.”
“I bought the car from a lady who had just moved back to Beverly Hills from Hawaii. While in Hawaii she saw the orange GTZ that was on the cover of the April 1991 cover of Road & Track magazine and wanted to have one built for herself. She called a Nissan dealer while she was in Hawaii that was in San Juan Capistrano, CA and ordered a Diamond Black Pearl Twin Turbo. She paid for it with a credit card. It cost about $40,000. It was then trucked to Stillen in Costa Mesa where the car was turned into a GTZ. She spent somewhere around $45,000 on the car to do that. She also had a car phone installed in the center console. It is still there and works. She also had TeleTrac installed which was a GPS tracking device in case the car was stolen, pretty rare at that time. Once the car was finished Stillen put the car in a wooden crate and it was air-freighted to Hawaii. She moved back to the mainland, got pregnant and decided the GTZ was not the car for a pregnant woman so she bought an Infiniti Q45 and had Stillen trick it out. I had the car serviced by Stillen, for the most part, while I was living in Phoenix.”
Mike recalls attending a Stillen Z meet in the 90’s and meeting Steve Millen for the first time with his GTZ. A recent visit to their facility in Orange County in 2022 yielded some great results:
“Steve Millen had sold the company and had moved back to New Zealand, but as I walked up the path to the front door of the shop an older guy was walking out of the building towards me….I was all…that looks like Steve Millen, and it was! We talked for a bit about the car and how he remembered it and the lady who commissioned it. He wrote a short letter for me stating that it was a genuine GTZ, number 6 in a series of 6 built by him. It also stated that my car was most likely the only one still in existence.”
The GTZ at Z Car Garage
We met Mike B in early 2022. He has owned this Z for 28 years and it was not running correctly so it came down to Z Car Garage from SF. We performed a full inspection, resolved some items while it was here and ordered several parts for it: “I was getting an oil change at a Nissan dealer south of SF a few years ago. While it was on the rack they noticed a few things that needed to be fixed. They didn’t recommend their dealer do the work and gave me Rob’s number and info. It was in the middle of covid so times were weird. They said Z Car Garage was one of the best in the country for Z work and I was happy to hear the shop was about 40 miles away from me. I went down to meet Rob and we discussed what should be done with the car to bring it up to snuff.”
The Z had an older exhaust system on it in rough condition. Rob had one in his parts stash so we hooked Mike up with a fresh Stillen axle-back exhaust system. We replaced all power steering hoses, rack bushings, valve covers, PCV valve, EGR, O2 sensors and everything under the plenum:
We installed Koni Yellow sport shocks F/R, lubed sway bars, and performed a full alignment. The passenger side door window motor failed, NLA but we had one and installed it. The oil was changed and car prepped for smog.
Dyno Tuning
With larger 740cc injectors we made a new chip so we could dyno tune it. It has a Greddy Profec b boost controller, set boost for 91 octane and made 310hp/352tq at the wheels. Solid gains over the baseline of 221hp/236tq:
The Stillen GTZ in action: walk-around, dyno runs and in-car driving with Rob and Mike B, enjoy!
Mike was really happy with the Z Car Garage service:
“Z Car Garage is great! I feel really confident that Rob does the best work out there and really knows his stuff. I took my car in for the boots etc and when all of the work was completed late last year my car was like a whole different beast! Rob did work on the engine like larger injectors and replaced all the fuel lines etc. He did some suspension work as well which took it to a whole new level. My first trip down to the shop, when the car was ready, Rob took me for a spin. That car had never handled like that before or performed like that. I think he said I got about another 100hp to the rear wheels after time on the Dyno. It was unreal to drive.”
“The engine pulls now like it has never before. The power comes on fast and it just feels like it can go and go! When Stillen first built the car they installed Bilstein shocks and Tokico adjustable struts. Over the years I had those replaced and the car never handled as well. When Rob was done with the car it now corners like it used to…like a road grader!! We took a corner near his shop at about 80, and this is a corner I’d usually take at about 40. It handled that corner like a race car, no body roll and tons of grip.”
With the mechanicals sorted, Mike went a step further and had paint and bodywork by our man William. Mike also had the original decals reproduced so the car now looks like it did back when it was built:
Mike’s GTZ at home in San Francisco. Although he’s owned it for nearly 30 years it’s time to let it go to another Z enthusiast. The GTZ is up for auction on Bring a Trailer right now! You can view the auction HERE
We enjoyed working your special GTZ, thanks for your support Mike and Long Live the Z! More photos in the gallery below:
To celebrate their 100,000 listing, Bring a Trailer is auctioning their 1973 Datsun 240Z, prepared by Z Car Garage. Finished in Lime Yellow (#112) paint over black vinyl upholstery, it is powered by a numbers-matching Rebello Racing-built 2.7-liter straight-six with triple Weber 40 DCOE carbs. Additional modifications include a 280ZX five-speed manual transmission, an R200 limited-slip differential, ZCG Big-Brakes, ZCG exhaust system and 16″ Panasport wheels with new Michelin tires. The total sale amount for the auction will be donated to the Piston Foundation, a nonprofit that will use 100% of the funds to help young technicians build rewarding careers in the collector car industry by funding programs in the skilled trades. View the auction HERE.
Z Car Garage built and maintained this Z for the previous owner since 2009 and updated it to BaT-preferred spec in 2018. It has since been used as an event car by BaT staff, with whom it has participated in many rallies, cross-country road trips, displays, and other events in the ensuing five years. Enjoy this video showing the Z in action and see below for more details:
The straight-six was bored and stroked from 2.4 to 2.7 liters by Rebello Racing and was installed at ZCG in 2011. Triple Weber 40 DCOE side-draft carburetors with K&N filters are mounted to its E88 cylinder head. Additional engine bay modifications include a polished valve cover, an MSD ignition system, and an inline fuel pressure gauge. Engine number L24-131094 is stamped on the block and matches the chassis plate. Rob dyno tuned the Z, making 203 horsepower and 190 lb-ft of torque at the rear wheels:
A replacement 280ZX five-speed manual transmission was also installed by ZCG in preparation for the sale. An aluminum flywheel and a heavy-duty clutch were fitted in 2011, while both clutch hydraulic cylinders were changed in 2018. Power is sent to the rear wheels through a custom-built driveshaft and an R200 limited-slip differential with a finned rear cover.
Factory black vinyl bucket seats were reinstalled, as was a stock steering wheel. The air conditioning system was converted to use R134a refrigerant in 2009, and was recharged as part of the February 2023 service at ZCG.An Alpine CD/MP3 player feeds aftermarket three-way 6×9 speakers mounted in a ported box in the rear of the trunk. Diamond-patterned vinyl trim is retained on the center tunnel and in the cargo area, while embroidered mats protect the carpets on the floors.
The Z has been stored indoors at BaT Headquarters in San Francisco when not in use. Details concerning the initial purchase and an ensuing cross-country drive from the Bay Area to Road Atlanta are chronicled in this seven-part feature from early 2018. The car has also been used in events such as:
2018 Copperstate Rally (as a photo and chase car, part of the cross-country trip described above)

Z Car Garage has built several cars with our client Randy Jaffe including the Rocketbunny Series1 240Z and #46 BRE Datsun 240Z driven by John Morton. In 2020 he acquired this cool 240Z East-African Safari Rally tribute and we helped him take it to the next level.
History and Acquisition
Randy’s Safari Z is a tribute to the original #11 car piloted to victory by Edgar Herrmann and Hans Schuller in the 1971 East African Safari Rally. Nissan campaigned three of these S30s in the rally, finishing 1, 2 and 7th place while handily beating Porsche’s and other marques along the way. It was a grueling race spanning over 3,800 miles and quite an achievement for the drivers and Nissan. #11 is currently displayed at the Zama Museum in Japan, still wearing its battle scars (more period photos in the gallery below):
Randy has always admired the Safari Z, keeping a 1/18th scale model on his desk for decades:
“I always loved the 1971 story where the Datsun Rally Z cars finished on the podium and just kicked ass over 3,852 grueling miles of torture!! A friend of mine built this car from an oddly enough a Safari Gold series 1 240Z – VIN 03227 with a 4/70 production date, Jim Faria – I almost bought the car from him in 2014 at San Diego ZCON but he decided he and daughter who do a few rally’s together which they did.”
Credit goes to Jim Faria for adding livery replicating the Herrmann/Schuller car with period front and rear spotlights, Nissan mud guards, rear grab handles, hood-mounted light pods and replica East African Safari plates:
The interior also features period touches like navigator’s equipment including 70’s route map, microphone headsets and rally timers:
Randy finally acquired the Z in 2020:
“Fast forward 6 years later at the 2020 Z Car Convention in Nashville. Jim placed the Safari Tribute for auction on Bring a Trailer. I was like ‘Jim you are selling my car!’ Eventually I won the auction and the Z was immediately shipped to Z Car Garage and featured in a Nissan commercial – from there on together with Rob we took this tribute to the next level.”
Z Car Garage Preparation
Randy shipped the Z from Georgia to our shop in San Jose, CA and we were first tasked with preparing it for a Nissan TV commercial. The Safari Z tribute would be in the “60 Years in 30 Seconds” commercial as part of “The New Nissan” ad campaign starring actress Brie Larson. Here are a few shots from the filming location:
With a little green screen action and some actual dirt driving (somewhere in SoCal) Randy’s Z looks like it is actually ripping through the desert plains of Africa, watch the actual TV commercial below:
https://www.youtube.com/watch?v=0a7oSMoU-Eg
Photos from the off-road adventure were used in subsequent social media posts by Nissan…this montage shows video clips from an Instagram post with the Safari Tribute getting loose in the dirt:
After performing its duty filming with Nissan, the Z returned to ZCG so we could add the remaining touches that Randy wanted. Here it is at the shop, still wearing its dirt after a quick rinse. Let’s take a look at the details we added.
Drivetrain
Randy wanted to proudly display this historic tribute in his collection, but more importantly (also why we love him), he wanted to drive it so people can see and hear the Safari Z in action. The stock L24 with SUs wasn’t going to cut it, this Z was getting the Jaffe-treatment with an engine to give it some go. A new 3.0 Rebello street race motor using a 10.5:1 head for pump gas was installed with a new 1982 280ZX 5 speed transmission and OS Giken 4.11 LSD.
We provided him with triple-Mikuni ph44 induction (as the original #11 Safari Z ran) complete with Harada intake, velocity stacks, linkages and Z Car Garage Heat Shield covering the Fujitsubo exhaust header:
Rob dyno tuned the 3L, producing 254hp/228tq at the wheels:
Enjoy this video of the Safari Tribute 240Z in action!
Details
Small details can make a big difference, like functional Works-style side jacking points, rear bumper steps and twin-exit exhaust system. We worked with Randy to knock-out his list of items:
“Rob and Gary found a source for the rear mudflaps that are a dead copy of the originals along with their brackets and the vinyl mat that sat in the rear hatch area with the 2 spare tires on top! So many custom pieces to get it right and Z Car Garage made it all happen. We installed new race type seats from Jay at JDM parts along with his version of the original Seiko wheels which the car really needed! I found some 175 x 14 tires made for Postal Jeeps that look very much like the Dunlops originally spec’d. Of course the original car is right hand drive but I’m good with what I have done to the car – maybe find the set of Heuer Monte Carlo stop watches that ran on the dash and that will be it!”
Those rear bumper steps were fabricated to be just like the original pieces. Original car on the left with Randy’s tribute on the right:
At ZCON in 2020 Pete Brock demonstrated how these were used (with grab-handles) by the Safari drivers to literally “rock” the Z out of sticky situations:
Randy enlisted help from industry veteran Dan Passe (Director, Nissan Corporate Communications) who had a Zama Museum contact measure the O.D. of the twin-exit exhaust tail-pipes so we could replicate them:
Mudflaps wearing the “Datsun” (as the original Safari Z) logo were sourced to replace the existing “Nissan” units and also proper steel hangers were installed:
The original East-African Safari Rally cars wore Kobe Seiko Competition Works Rally-Magnesium wheels. These are difficult to source but reproductions are available. Randy is running a set from Jay Ataka of JDM Car Parts. Tires are hand-cut from a Postal service Jeep by Bryson from Classic Livery (of Leh Keen Safari 911 fame). Original on the left:
Inside, the original style REPA race belts were replicated as close as possible. The original Safari car ran Z432 seats, as seen on the Salt Flats 240Z we helped revive. These are also difficult to source so we used race-style seats from JDM Car Parts to replace to stock units:
Here is the Z at home in Georgia with Randy now featuring all of the parts/details:
Enjoying The Ride
Before heading back to Atlanta, Randy enjoyed driving the Safari Tribute during Car Week at Monterey. What a car to cruise in, and he even visited the paddock at Laguna Seca. Here are a few more shots from Randy of the Z in Georgia. We love his new “ZAFARI” (previously “SAFARIZ”) license plate:
We have many photos in the gallery below and don’t forget to see the Safari Z featured on Hoonigan Autofocus (now Larry Chen’s own channel) also looking at Randy’s epic Datsun collection.
Thank you Randy for your passion and continued support. We loved working with you to re-create fun details for the Safari Tribute. Long Live The Z!
