Nathan was super excited with the results and fueling upgrades are up next. Long Live Boost and Long Live the GT-R!
Our Z Car Garage Big Brakes have been winning over Z-car enthusiasts locally and globally. Kim recently purchased a set for his 1970 Datsun 240Z and performed the installation himself at home in Norway. Before we go into his Big-Brake experience let’s hear his Z-story…
Like many enthusiasts, Kim started with a Miata…
“After owning a modified Miata for several years it was time for another project car. I still have the Miata, but that is more for track use now. I was not actively looking for a 240z, but I came across my Z car on a Norwegian sales site. I went to have a look and the car was in good shape, and the price was so low that I just had to buy it. It was repainted in 2005. The paint job was ok, but not perfect. All interior panels, dash and seats were re-trimmed in leather.”
Modifications include Tokico dampers with Ground Control coil-overs and a Nissan 6-speed CD009a transmission using the Hoke Performance kit. Kim was heading to the track and eventually installed a Datsun Spirit 3.1L engine with Jenvey ITB EFI, ported head and custom exhaust. Yes, that’s Kim’s Z on the Nurburging!
You can see the dyno run and acceleration in Kim’s Z in the video below:
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

Big-Brake Kits Available For DIY Install!
Z Car Garage is proud to offer our Big-Brake Kit to Z-Car owners that want to perform the installation themselves. We can ship worldwide and each kit contains everything needed with a comprehensive (40-page) installation guide. Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. Enjoy these pictures of Kim’s beautiful Series 1 S30 and his ZCG Big-Brake installation:
As mentioned, our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake. Kim successfully installed the BBK on his Z, and they also look great behind the Work Equip 03 wheels and newly installed fender flares:
“I had a brake kit from Silver Mine Motors and used those for several years. With the new engine and higher HP numbers I really needed a brake upgrade. StopTech from Z Car Gar Garage was the way to go. The installation was quite easy. I did have some questions, and I got answers really fast. They feel awesome.”
Beyond ease of installation and quality components, our Big-Brakes perform by offering superb pedal feel…everyone that drives our demo Z confirms! 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.
What’s in store for Kim’s Z?
“I take everything as they come, and find a new upgrade I like to try from time to time. Well, the goal is to have a car that works every year and I can modify during the winter. All lights are upgraded to LED from Classic Car Leds. AC from Vintage Air, upgrading the engine wiring harness, and consider some wider tires to fill the arches a bit more.”
Thanks for your support Kim we love that you are Enjoying The Ride and Long Live The Z! More photos in the gallery below

At Z Car Garage we enjoy both modifying Z cars and restoring them back to original spec. Mike’s 1970 Datsun 240Z came to us from North Carolina for finishing work and now this 11/69 production (VIN#193) S30 is a beautiful driving example of how wonderful these cars were from the factory.
We met Mike and his amazing wife Debbie through our client Randy Jaffe. In the 70’s and 80’s Mike, his brother and dad were doing all kinds of Z car stuff and Mike later went on to be a car collector of some of the finest examples of cool Datsuns including a Nissan Fairlady Z432, multiple low-vin # S30s, and a 12-mile 10th-Anniversary 280zx:
Mike’s history with VIN#193:
“According to all my research, #193 is the 75th oldest Datsun 240z in existence. I bought this car and started restoration in 2014. I did most of the work myself after dealing with a few people who never should have been in the restoration business. I have over 50 years of working on Datsun Z’s so I knew the car well. After 8 years of sourcing parts and pieces, most of which are pretty rare on 1969 cars, I got to the final stage of finishing the car. I knew of Rob’s expertise on these cars, so I turned it over to him to finish. His reverence for the car was greater than mine. He continually was calling me and proposing things that I never knew.”
The Finishing Touch at Z Car Garage
Mike had been working alone on VIN #193 and he called upon ZCG to take it to the finish line. The car was shipped to us from North Carolina and we identified many things that were done incorrectly. Mike also had a pick list for us and the goal was to restore this S30 back to Series 1 spec. We sourced all of the parts and with attention to detail to ensure this car could drive anywhere and also showcase the beauty of an unmolested Series 1 Z. Enjoy our detailed photos in the gallery below and let’s start with the interior…
Interior
Many parts were missing that are specific to a Series 1 car like turn signal and headlight switches, Series 1 cables and heater bracket tabs. We ensured everything in the dash area was functional:
We also restored the interior vinyl and replaced the hatch seals Anything that was not correct on this Z we did everything in our power to make it look like it was 1969 and it rolled off the showroom floor.
Scissor jack cover and seat trim:
Engine Bay
Series 1-specific items were missing or incorrect in the engine bay. Since this was a an 11/69 production car it needed a 1969 Fuel rail. The way the distributor standoff is, SU bowls, plugs, hose clamps and other small items like a black-painted hood prop were corrected. If Mike took this S30 to a Concours event it would do well.
An often overlooked detail are the hose clamps around the SMOG equipment. Very early cars like #193 had silver hose clamps instead of matching yellow/gold-plated finishes because smog equipment was added in the U.S. Mike was unaware but appreciative of this.
Chassis
The chassis was nut and bolted after we went through the hydraulics and checked the braking system. Factory markings like the (R) and (L) stickers on the struts were added:
The transmission was wrong so we installed an early Series 1 unit:
More chassis photos in the gallery below!
Details
All of the early series 1 and S30 wheels were date coded. We sourced the correct, 69-date coded wheels that are correct for Mike’s car:
Small details: Series 1 lock assemblies, weatherstripping and early day/night “red dot” rearview mirror:
Dyno Tuning
We baseline dyno tested the Z and it made 102hp/113tq at the wheels. With Rob’s tuning it made 114hp/125tq to the wheels:
Once all systems were go we performed a road test followed by a full detail. Mike’s car was loaded onto a transporter and headed back home to North Carolina:
Enjoy this video of Mike’s 1970 Datsun 240Z in action with dyno runs, in-car driving and walk-around:
Mike was more than satisfied with our work on #193:
“Rob’s Z Car Garage is truly the best place to do any kind of work on any Z car in this country, in my opinion, and he will be the only person to work on any of my cars, ever!!!! When you find the best, now you know the best, so never get too far away from that guy!!!
He wanted Z Car Garage to work on his other Datsuns so he shipped us a few more cars from his collection in North Carolina including this 1977 V8-powered 280Z, 510 vintage race car and RB25DET-powered 240Z. We will have updates on these cars coming to zcarblog.com soon!
Auction Bound!
Mike will be offering VIN #193 and 7 other cars for auction at Mecum in Monterey on August 17-19. In addition to #193 here is a preview of the exciting Z cars offered from his collection:
1970 Fairlady Z 432
4 valves, 3 carburetors, 2 cams. Only 418 of these cars were built between 1969-73 and only 200 were built in 1970. This car had been restored in Japan as well as London, which is where it was acquired. Slightly modified but all numbers match (number 105) and it has Magnesium Watanabe wheels.
12k mile 280ZX
This 1980 10th anniversary 280zx is 1/500 in red/black. In 1980 there were 1250 Datsun dealers in the U.S. so every dealer got a black/gold one. The top 500 dealers got a red/black one. Gerry Ellis Chevrolet-Datsun in Baton Rouge, Louisiana was a top 500 dealer. It was a trophy to him so he put it in a warehouse at his dealership and covered it up. He never would sell it and it sat there for 40 years. Purchased with 12 miles on the clock (now has 26miles!). Check out this video of the 280ZX from this ZCON 2021 and an in-depth look with Randy and Mike below:
1972 Datsun 240Z (Vintage Z Program)
This 1972 240z is 1 of the 37 factory restorations done in 1996. Nissan was waiting for the 350z to be finished and decided they would find 250 cars in the southwest U.S. that were rust free and they would ship all the spare parts they had at the factory to restore them and sell them as new cars with a factory warranty in select Datsun dealerships. This plan was to keep the Datsun Z name alive to the public. They planned on 250 but it cost so much to restore them that the program ended after only 37 cars. This is one of those 37. Super rare car!
Thank you Mike for your support and letting us help you restore #193! More to come from Mike’s Datsun collection and Long Live The Z!

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:
