Mike’s 1991 Nissan Skyline GT-R

Filed under: Featured Cars and Projects,Performance,r32
by Alvin G @ 5:53 pm on June 30, 2020

 

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:

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.”

 

Along with the turbo kit, we will be adding: PWR radiator, Samco radiator hoses, Tomei Type B Poncams, fuel pump, Radium fuel rail, fpr, ID 1050X fuel injectors, along with a custom intake and custom intercooler piping with a Tial q50 BOV. The goal for this round of upgrades is 500whp on low boost and 91 octane fuel.
“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!

240sx Update: Brakes, Turbo, Tuning

Filed under: Featured Cars and Projects,Performance

Gary S. is a guy on a quest…to own each example of Nissan perfection. Lets begin the next chapter in Gary’s 240sx as it gets closer to that vision of exellence!
With the G35TT being what it is, Gary’s back-up car must have the same 3-dimensional qualities of big power, big brakes, and suspension. The to-do list included cleaning up the work done by the previous owner, and improve on an already amazing ride.
When the 240SX arrived from the east coast it already had the SR20DET engine swap, stock MAF, stock turbo, and boost controller. We dyno’d the car in stock configuration: 205hp/193tq at the wheels indicated a clean bill of health. Let the modifying begin.

We made a plan to make nice power on 91 octane with big torque throughout the mid-range to help Gary forget his new ride only has 4 cylinders 🙂 We installed a more “adult” exhaust to replace the loud RS*R muffler. Made by BRM, this exhaust is fairly priced, has perfect fitment, and most of all the twin-tips look very close to the factory outlets!


A call was made to Clark @ JWT and we wired in the Z32 MAF, installed the NISMO 740CC injectors, and plugged in the new ECU upgrade from JWT. We knew the stock turbo would never meet the power and torque requirement…come on it’s Gary…So another call was made, this time to the folks at TOMEI USA:

We decided to run several TOMEI components so off came the valve cover to install the S14 Poncams, rocker stoppers, TOMEI Expreme stainless turbo manifold, and turbo outlet pipe. TOMEI had just released the M7960 turbo and we told them we would give it a try and report back on the performance level. Behold the turbo manifold in all it’s glory….before it gets wrapped with high temp tape:

The stock manifold + turbo vs new Tomei setup….Hey Gary that old T28 is going into Alvin’s roadster, right?


Once the parts were installed we ran the Wideband 02, plugged in our Consult II and went out for a test run. The MAF voltage was higher than I had ever seen on a turbo car at this boost level. Once the boost kicked in…it was enough to put you firmly back in the seat.
On to the dyno…power levels were very nice, but at the top of the rpm range we were having trouble holding steady boost. 338hp and 305tq to the wheels with a great powerband was nice indeed.

We checked all of the usual suspects to sort out the boost issue but no answer. TOMEI USA was contacted and they are willing to help us find a way to get the desired power with a steady boost pressure: To be continued…

…Back to the car…
Big power is a great thing but driving a car that can only go fast can get old very quickly. It is no secret that ZCG loves using Stoptech Big-Brake-Kits…we have tested them on the street and the track with impressive results. It’s about time serious hp power met serious brakes on these cars! When was the last time you saw a set of these on a 240sx 🙂 Larger rotors, stainless lines and appropriately sized master cylinder round out the upgrade. To match the front calipers the rear Z32 calipers were finished in red/white lettering:

The 240 already came with a sweet set of bronze 18″ Nismo LM-GT4 wheels, here is the before/after Stoptechs up front:

Of course the bronze looks great against the white body but Gary wanted a more low-key appearance so the wheels were re-finished in black:

The next steps in the 240SX project will be to sort out our boost issue,  install some suspension upgrades and gauges. Here are a few more pics of the car with the new look:

Long Live the Man With The Most Nissans!
