R’s Day, one of the largest gatherings of Nissan Skylines on the West Coast was held on December 7, 2025 at Laguna Seca Raceway. Z Car Garage attended the event and supported our client Kurt in his R32 GT-R. Rob brought out the Bay Area Datsun Dealers 510 and several ZCG clients all had a great time. Enjoy our report with photos and videos!

 

Kurt’s R32 GT-R

We prepared Kurt’s R32 Skyline GT-R for the track day. Earlier in the year it received a fresh RB26 motor and turbo upgrade to complement the new KW coil-over suspension and Stoptech Big-Brakes….

Rob’s Vintage Racing Datsun 510

We also dyno’d Rob’s B-Sedan vintage racing Datsun 510:

 

Here’s Rob’s report from R’s Day…

ROB: Cooper and I loaded the BAAD car to Laguna Seca, our home track during the vintage race season. It was really fun to bring out my Datsun 510 race car with all those cool street cars. We had Dirk stoop in his 1973 Datsun 240z, Amy in her RZ34, Joseph in the RZ34 # 49 car, and a few others including Miles’ R32. Our main focus was to support Kurt in his R32 GT-R which has been modified and tuned by ZCG, full report coming to zcarblog.com soon.

 

I’ve been to a few R’s day and this was the first time I’ve driven. Each event has seen a steady increase in attendance and it was the most R32, R33 or R34s I’ve ever seen. It was incredible to be in a paddock filled with lots of cool Nissans… There was Pat’s RB-powered Pat’s Kenmeri (featuring our ZCG CV Axles):

 

All kinds of really cool cars and kudos to the R’s Day team as they were just super organized: the meetings and downloads were quick and informative. I love their grid process. Everything was just wonderful and we will definitely be back next year. Kurt’s car rocked. There were some pretty fast cars  including Charles Park from Powertrix with their time-attack R35 tuned by SpecialtyZ. Sean Morris and Brian J from Top Rank, people from all over the California GTR scene. Todd Lapin from Norcal Skylines cooked HotPot in the garages! It was just a very festive, community-oriented vibe and I had a blast.

 

Dirk’s 1973 Datsun 240Z

 

Dirk’s 1973 Datsun 240Z features Z Car Garage Big-Brakes (StopTech), Z Car Garage CV Axles, Silvia 6-speed transmission and a host of chassis and driveline upgrades. Rob dyno tuned the 3.0L Rebello L-series engine with triple-Mikuni ph44 carbs, making 265hp/231tq at the wheels.  We prepared the Z for R’s Day and Dirk had a great time:

DIRK: Yeah dude, massive difference! Work done by ZCG just before the day:
1. New rear sway bar (ST suspensions), car did not have one before, last Sonoma track day, being able to rotate the car on entry was difficult, this change was made to help that
2. New RE-71RS tires, Rob found old tires were pretty much spent, Dirk ordered tires, car stayed at ZCG an extra day so that they could be installed before the track day
3. Suspension and brake inspection
4. Change diff and trans fluids

Car rotated much better with the new rear sway bar, now able to rotate just by lifting off throttle in turns, quicker, and more fun. Felt great, very predictable and forgiving at the limit.

Joseph’s 2023 Nissan Z

 

Joseph’s 2023 Nissan Z proudly wearing the Joel Anderson-inspired #49 livery:

JOSEPH: It was a beautiful day at Laguna Seca (as if anything else is possible) with GT-Rs from every era, as far as the eye could see! There was also a very famous 510 in the mix…The #49 new Z ran great on its new 18×10.5 SSR wheels (275-35-18 Nitto NT01), but the day was cut short by cleanup of an oil spill from turn 6 to turn 10, and one of my brake pads deciding to delaminate in the heat on the way into turn 2. We’re putting race pads on next time! I made my goal of breaking 1:50, so I left with a smile on my face anyway.

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:

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.

 

“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.”

 

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!

Pall K acquired this Pearl Red (AH3) R32 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.  We love the gorgeous paint color and Volk TE37SLs:

 

Pall brought the R32 to ZCG for a full inspection. We found one of the CV boots torn and he had some Nismo stainless lines for us to install.

  

We checked the timing, changed the engine oil, transmission fluid and installed the new brake lines front/rear:

   

Full alignment, and the Skyline will be coming back for a clutch service:

 

Pall enjoys driving his R32 and even made it to the Norcal Skyline Matsuri last month:

   

We really enjoy taking care of many Norcal Skyline owners.  Welcome to ZCG family Pall and thanks for trusting us with your R32!
