The Championship-winning 1988 Nissan GTP ZX-Turbo is at Z Car Garage. This iconic race car was driven by Geoff Brabham and John Morton, known for de-throning the Porsche 962 in IMSA racing with 8 straight wins. Enjoy the photos of chassis #8801 with a full feature coming soon to zcarblog.com!
Thanks to Dean Case and Greg Nelson of Nissan Motorsports for the opportunity to have this legend here at Z Car Garage.
It’s surreal to see the car that has been a poster on our wall actually inside the shop. Rob had to get out his R/C car and another poster from the front office:
Enjoy this video highlighting the epic 1988 IMSA season with Morton and Brabahm in the GTP ZX-T:
We met Lehan in the summer of 2018 when he came to Z Car Garage with his newly acquired (KH2) 1991 Skyline GTR. After learning that these cars can be made smog compliant, he found this car locally (originally imported by our friend Sean and his team at Toprank International Vehicle Importers) and picked it up right away. We replaced the clutch and flywheel with an OS Giken TS2CD setup, replaced the rear main seal and fresh clutch hydraulics.
To fix an intermittent misfire we installed R35 coil packs ( a common RB26 upgrade) and replaced the front CV axle boots. Lehan’s goal for this R32 has been modest:
“I’ve changed the wheels and exhaust to more of my liking, replaced worn rubber parts and trim pieces, and added some Nismo bling. My goal with the car is to keep it looking mostly stock, but update the drivetrain to more modern tech, hence the Haltech ecu. In the future I may replace the 30 year old turbos but keep it to a modest hp gain, and replace the Attesa G-sensor with a digital unit. I will probably keep the HICAS system just because, and learn to drive with it on the track.”
Haltech ECU and Tuning
In March of 2019 we installed a Haltch Platium Pro Plug-in. It was set up to run MAP-based with the Haltech WB1 single channel wideband 02. We are huge fans of Haltech engine management. Rob performed street/dyno tuning tuned on 91 octane with baseline numbers of 260hp/253tq and with the Haltech making 337hp/280tq at the rear wheels:
Enjoy the dyno video!
Stoptech Big Brakes
All 90’s Nissan sports cars can benefit from larger brakes and Stoptech has got you covered. Another Norcal Skyline member Kurt W also had Stoptech brakes installed at ZCG, and he highly recommended them. Lehan’s R32 received ST40 calipers with 332mm rotors up front and ST22 caliper with 328mm rotors at the rear.
A few pictures of the brake installation:
The brakes look great behind the BBS wheels. During the brake upgrade we replaced all fluids: both diffs, tranny and transfer case.
Lehan took the R32 to a track day it performed admirably. He did experienced high oil temps, another common issue when tracking these cars. A new oil cooler will be installed next. Over all he’s please with the Skyline’s upgrades:
“Every visit to fix or update something just makes the car more awesome to drive. It feels much more lively and torquey after the tune. Best part is I can drive it as hard as I can knowing it’s been tuned safely and backed by modern engine management. It’s a similar feeling with the StopTech brakes on track – without it I would not have been able to push braking points. The steering feel and overall composure of the car is top notch, especially after the tune. I’m very happy with the car as is, but definitely looking forward to any future mods.”
Enjoying The Ride
Lehan has been driving the R32 everywhere including the track and autocross. We spotted him at the inaugural Fuel Supply Co. gathering earlier last year.
He even made it out to the Norcal Skylines Matsuri, an event we were lucky to attend 2019:
We love helping our local Norcal Skyline Owners repair, improve and enjoy their cars.
“It’s been awesome working with Rob and ZCG, and I’m really happy with all the work they’ve done. This is my first car with significant modifications, and I liked that Rob doesn’t push to have it done in a specific way. I also appreciate Rob’s effort to ensure the car is as best as it can be. I noticed some rubbing the week before a track day, and he was able to check that out on short notice, and offered to help if anything came up. True to that, I texted Rob about high oil temps the day of and he replied right away. I’m getting an oil cooler installed early Jan before the next track day.”
Thank you Lehan for your support and we look forward to working with you! More pictures in the gallery below:
Last week our friend Eric Straw visited us for tuning on his incredible RB26DETT-powered 1984 DR30 Skyline. You might remember Eric stopping by the shop last year on his way down to the JCCS show, where the DR30 put down 462hp/348tq on our dyno. Eric expressed interest in more power without sacrificing reliability:
“The only plans I have for it at this point is a pair of GT2860RS, new injectors and Haltech Platinum Pro Tuning by Z Car Garage in spring”
So spring arrived and Eric collected his parts including new GT2860RS turbos, Radium Engineering fuel supply, Injector Dynamics ID1050x injectors, and a Haltech Platinum Pro from ZCG. Rob began dyno tuning sessions and road data-logging.
Eric wanted the Skyline to run on Oregon’s readily available pump gas, and the result was 532hp/389tq to the wheels on 92 octane. Power delivery is very linear and Eric’s fastidious chassis-prep harnesses the power so well it is hard to believe you are riding in a 80’s Japanese car! Here is video of the DR in action:
Our good friend Michael Spreadbury accompanied Eric on the roadtrip down from Oregon. Michael was instrumental in the DR build and is a well-known Datsun-guru building some killer SR20-powered roadsters from his shop at Spriso Motorsports. While the two were in town Rob shared the Nissan Patrol and had the boys put some miles on the DR30 after the fresh tune.
On Saturday 4/15 we had a great opportunity to take the DR30 to Laguna Seca and watch Patrick Chio race in the USTCC and our customer Kevin B enjoy a track day. I had to join in on the fun with my roadster 🙂
The Skyline was impressive to watch on the freeway. From inside it feels like it is carved from billet with surprising balance between ride stiffness/NVH. Oh, and that RB26 is velvety-smooth with thrust for days. We think Eric is quite happy look at that RHD smile!
Laguna Seca was filled with plenty of eye candy. We even saw a few BAYZA Z32s/Z31s! Always fun to see owner’s solutions to the ever-changing sound restrictions:
Laguna Seca also makes a fantastic backdrop for photos.
At the end of the day we snuck into the garages to capture some “pretend” race-day shots:
The trip home was exhilarating. The DR30 has some glorious 80’s lines and those after-burner tail lights glow just right at dusk:
We had a rad time with you Michael and Eric! Enjoy The Boost!
