Mike R acquired this gunmetal (KH2) 1991 Skyline GTR from Toprank International Vehicle Importers in 2019. Z Car Garage is familiar with the Norcal Skylines group and fellow R32 owner Kurt W referred Mike to us in addition to an endorsement from Top Rank. Mike’s first round of upgrades included a Project Mu Big-Brake kit, Ohlins coil-over suspension, Haltech ecu, Greddy FMIC, sorting and dyno tuning. All of this work is documented in our 2020 blog post:

 

More Upgrades

Following that initial visit, Mike added R34 GT-R Seats, and a sweet set of Volk Racing TE37 SL custom gloss black wheels (18×10.5 +15), wrapped in Michelin PS4S tires (265/35/18). A Haltech IC7 digital dash was added to monitor vital engine parameters, tying into the CAN box of Elite system:

Add More Boost

Mike was happy with the upgrades we made but like many of us the desire for more power inevitably hits:

“The car has been running flawlessly and the goal with these mods is to support the addition of a single turbo kit that ZCG will be installing this August. The turbo kit consists of a Full Race Twin scroll T4 manifold that will be mated to an EFR 8474 turbocharger. Twin Tial 44mm external wastegates will bleed off the excess exhaust gasses.”

Mike’s R32 came back to ZCG in 2022 for a few more items including:

ATS Carbon twin disk clutch (shoutout to @wubbs18)
New oem timing belt and pulleys
PRP alternator kit
Kansai Service Towhook
OEM Valley cover powder coated with R34 ornament plate
Mines Alcantara shift boot, parking brake handle and boot

Dyno Tuning

Several dyno tuning sessions were performed during the upgrade period. 515hp/437tq on 91 octane was achieved with significant mid-range gains:

 

Mike was pleased:

“Big thanks to @zcargarage for seeing this project through to the end and making the car come to life. We had a lot of headaches and setbacks over the past 11 months, but they did an incredible job end result speaks for itself! Couldn’t be happier. 🤘”

E85 Fuel

“Ethanol delivery is handled by a full Radiumengineering fuel system. Fuel hanger surge tank using twin 525lph to feed the rail and a 340lph to feed the hanger. All new hoses with a -8 feed line. Radium fuel rail with Rail mounted adjustable fuel pressure regulator. All feeding Injectordynamics ID1700XDS injectors. Haltech Flex fuel Sensor and Bosch Fuel pressure/temp combo tied into Haltech Elite to bring it all together.⁣”

On the dyno with E85 the R32 put down 624hp/479tq at the wheels, and Mike continued to enjoy the car:

“So the car has been on flex fuel for a few months now. Made 600 whp and 480tq. Still just keeping the boost around 20psi. Tons of room left in the setup. Been enjoying the shit out of the car is it currently sits. Maybe some minor cosmetic stuff in the near future, but for now….just drive.”

Enjoying The Ride

We were happy to see Mike Enjoying the Boost and spotted his R32 in action at the Tokyo Calling and Breakfast Club Rallies in Northern California:

Mike R acquired this gunmetal (KH2) 1991 Skyline GTR last August from our friend Sean and his team at Toprank International Vehicle Importers. It goes without saying, if you are in the market for a vintage Skyline (or any JDM car) IVI is the place to go.

Z Car Garage is familiar with the Norcal Skylines group and fellow Skyline R32 owner Kurt W. referred Mike to us in addition to an endorsement from Top Rank:

“One of my main concerns in purchasing a 25+ year old vehicle that was never manufactured in the US, was support. Who can work on this thing to perform maintenance and upgrades? I spoke with Top rank about it quite a bit prior to purchase and they had recommended Z Car garage. The car was in great condition and mostly stock when I got it. With the goal of being an all around fast street car, I started acquiring parts and placed a call to ZCG to start the first round of upgrades.”

Chassis

We discussed installing a big-brake kit, suspension, Haltech and a few others issues we handled for Mike. Here is the Project Mu 4-wheel big-brake kit:

We also installed the Ohlins DFV coil-overs, shown below are the stock R32 calipers:

With a few modifications the Project Mu kit was installed:

Some close-ups of the Project Mu setup:

We adjusted his coil-over setup and set the ride height followed by corner-weighting the car according to his weight. Further suspension mods included Whiteline Sway bars, Cusco strut bracing and SPL titanium HICAS eliminator kit. All interior panels were trimmed for a clean finish with full alignment services.

Performance

Mike was also interested in replacing the factory ECU so we upgraded to a Haltech Elite 2000 with the R32-plugin adapter. The full installation also included a wideband controller and smoke-testing the car in preparation for dyno tuning:

Greddy FMIC:

The Haltech combined with Apexi intakes, Nismo downpipe, Tomei Titanium exhaust, Greddy FMIC and PRP R35 Coil kit, netted 340hp/284tq at the wheels with Rob’s tuning on 91 octane:

Enjoy the dyno video below:

Since his last visit, Mike has added R34 GT-R Seats, and a sweet set of Volk Racing TE37 SL custom gloss black wheels (18×10.5 +15), wrapped in Michelin PS4S tires measuring 265/35/18.

Mike also relocated the battery to the trunk to make space for a Leaskspec radiator overflow tank and Radium dual catch can setup:

In addition, a Haltech IC7 digital dash was added to monitor vital engine parameters. The IC7 dash ties into the CAN box of Elite system:

More Power

Mike has been happy with the upgrades we made but like many of us the desire for more power inevitably hits:

“The car has been running flawlessly and the goal with these mods is to support the addition of a single turbo kit that Zcar will be installing this August. The turbo kit consists of a Full Race Twin scroll T4 manifold that will be mated to an EFR 8474 turbocharger.  Twin Tial 44mm external wastegates will bleed off the excess exhaust gasses.”

“All of the work performed at Zcar had exceeded my expectations so far (and I’m very picky). Looking forward to the start the build and make some power of the next few months.”

We really enjoy taking care of many Norcal Skyline owners.  Welcome to ZCG family Mike and thanks for trusting us with your R32! Enjoy The Boost until you return!
