Add More Boost: Mike’s 1991 Nissan Skyline GT-R

Filed under: Performance,r32,Skyline
by Alvin G @ 3:32 pm on January 11, 2024

 

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.”

 

Along with the turbo kit, we added a PWR radiator, Samco radiator hoses, Tomei Type B Poncams, fuel pump, Radium fuel rail, FPR, ID 1050X fuel injectors, custom 4″ intake and intercooler piping. See the full modification list below. The goal for this round of upgrades was 500whp on low boost and 91 octane fuel.

Remade in USA throttles and Nismo plenum. Fully built cylinder head with GSC S1 cams, SuperTech valves, springs, retainers, guides:

 

PRP crank trigger kit, Radium Dual Catch cans, Custom Intercooler piping with Tial q50 bov and Nismo oil cooler:

 

HKS Super Turbo Titanium exhaust:

 

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:

Paul’s Nismo 370Z

Filed under: 370z,Featured Cars and Projects,Performance
by Alvin G @ 5:34 pm on June 30, 2023

 

Paul K is a local enthusiast out of Campbell, Ca and he visited Z Car Garage for basic performance upgrades on his 2011 Nismo 370z:

 

“I had always wanted a V1 Nismo and in 2018 searching online I found one at a dealer in Sunnyvale. One owner with 26k miles and garage kept. Rob has helped install Stillen dual intakes, Fast Intentions dual exhaust, and Ecutek tune. Other mods mods include Tein S Sport lowering springs and Stillen crossed drilled and slotted rotors. Many more mods planned with Rob!”

 

Dyno tuning and Stillen intakes are a great way to start the modding process and Z Car Garage is here to help! We intalled the Stillen Gen3 intakes which are CARB-legal and work wonderfully on the HR engines:

 

Before/After

 

To maximize gains from bolt-on modifications we dyno tuned the Z with Ecutek software making 315hp/260tq to the wheels:

 

We also installed a Fast Intentions cat-back dual exhaust system:

Paul can be seen all over the Bay Area Enjoying the Ride in his Z34:

“I’ve noticed a gain in performance and enjoyment in driving the car. Feels much more aggressive and responsive. Every time I’m at ZCG, it’s always an enthusiastic experience dealing with Rob and his passion for Z’s.”

 

You can see more of his Z on his Instagram. Paul was referred to us in 2019 by long-time customer Chris R, owner of this soon-to-be featured 240Z formerly known as “Skittles”:

 

Thanks for your support Paul and LONG LIVE THE Z!

TUNING: Sean’s 2010 Nismo 370Z

Filed under: 370z,Performance
by Alvin G @ 3:42 pm on April 13, 2022

 

Sean M visited Z Car Garage for dyno tuning on his 2010 Nismo 370Z. We specialize in UPREV and EcuTek Tuning to maximize power gains from individual modifications like intake and exhaust upgrades. Let’s hear how Sean found his Pearl White V1 Nismo Z34:

“I obtained this car through my father’s best friend. A couple of years ago, I found this car on craigslist and I wanted to jump on it very badly. I had just gotten a car six months before, so I couldn’t get it and knew it was going to be gone within the next couple of days. Sure enough, that’s what happened. I showed up at the Thunder Hill 3-Mile course that weekend, and spotted the car parked next to our trailer when we arrived. It turns out my father’s best friend bought the car, and from that moment I told him that if he ever wants to sell it, I want to buy it from him. About a year and a half later, thats what happened!”

 

Once he got the car Sean started modifying it immediately with Stillen G3 intakes, Z1 headers, Magnaflow cat-back, Z1 motorsports 34 row oil cooler, Z1 clutch, KW V3 Coilovers, Hawk DTC60 pads, and AEM Oil pressure and wideband AFR gauges.

“After installing those parts, I knew it was going to need a tune. Thats when I found the man the myth the legend Rob at Z Car Garage! I found them online looking for Z tuners in the bay, and after coming into Z Car Garage I knew I brought it to the right place. Rob got the car squared away with the UPREV ARC license, and with his knowledge about how hard the car gets driven he dialed it in.”

Dyno Tuning

 

We specialize in UPREV and EcuTek Tuning to maximize power gains from individual modifications like intake and exhaust upgrades on Sean’s Z. On the dyno, Rob UPREV tuned with gains throughout the rev range. Peak gains of 20hp/20tq for a total of 335hp/272tq at the wheels was achieved:

 

Enjoy this dyno video that Sean filmed:

Sean was stoked on the dyno results:

“Being a huge racer himself, he knows what it takes to keep a car maintained and up to date, and the motor running safely and efficiently. Z Car Garage is always my recommendation to fellow Z enthusiasts, as I know Rob is a wealth of useful information as well as a brilliant mechanic. After the tune, the car has fantastic throttle response on partial throttle and tons of top end!”

 

We also added the ARC (Advanced Racing Controls) license. This add-on service to the existing UPREV Flash allows you to have adjustable launch control, burnout mode, and flat-foot shifting. This is for cars with manual transmission, VDC/cruise control. Call Rob for more details and to schedule your Z/G tuning appointment.

Here is a video of the exhaust and launch control (courtesy of the UPREV ARC License):

 

Enjoying The Ride

 

Sean is an avid driving enthusiast and this Z sees the track 2+ weekends per month, running strong each and every time. It is a car that gets driven close to its limit, and is often featured on Sean’s YouTube Channel, Milburn Motorsports. You can also catch Sean and his racing adventures on Instagram.

 

Rob had a great time with Sean:

“We met Sean through tuning his car. He’s an awesome young man and even brought some of his friends (some we’ve also worked with) with him to the shop. It’s good to see passionate, enthusiastic young people in motorsports.  Whenever Sean is here we talk about his Z car and how much he enjoys it and how we both enjoy driving. He’s got a really cool YouTube channel that we subscribe to and he’s an excellent racetrack driver.”

Thanks for your support Sean, Long Live The Z!

Z cars may remain with their loving owners for years, change ownership or even get spotlighted in the media at some point. Our “where are they now” series features past Z Car Garage vehicles with updates on their status. In this third installment we catch up with Craig’s 2004 Nissan 350Z.

 

Craig’s 350Z was supercharged almost 12 years ago using a Vortech Tuner Kit with supporting fuel and cooling upgrades.

 
 

Fast forward to 2022, Craig visited ZCG for routine maintenance including a new air filter and rear differential bushing replacement:

 

The diff bushings were replaced with new units from Whiteline. The diff bushings are the most common failure as see in previous blog posts:

 

We put the Z on the dyno and it put down almost identical power output some 12 years later! This is a testament to the mighty VQ35 engine and Craig’s maintenance. Dyno plots:

(L) 2022, the Z made 420hp/349tq at the wheels

(R) ~2012, the Z made 415hp/344tq at the wheels:

 

Enjoy the latest dyno passes of Craig’s 350Z in the video below:

 

Craig is still happy:

“Even after 12 years or so, every time I drive my Le Mans Sunset 2004 Touring model, I feel like it’s the first day. Aligning with the team at Z Car Garage was the best move. I didn’t need to shop around once I visited a few times. I knew I was at the right shop.  Buying the Z in 2008 was exciting as this was the first sports car I’d ever had. Having the performance upgrades a couple years later from Z Car made a world of difference. So glad Rob  helped me “pull the trigger”. Without a great deal of knowledge of what I wanted in components, I let Rob custom-craft what he felt (and had solid experience with) was the best mix for me and the car.  I’m pretty tall, so I don’t track the car, which is a bummer at times, but I have as much spirited driving as I can. Also, I live about an hour from the shop, so Rob and team make a point to take care of me when I do visit, reviewing maintenance items needed.”

 

Thanks for your support Craig! We love that your Z is still running strong and you continue to Enjoy The Ride. Stay tuned for our next “Where are they now” feature, and if you missed our first and second features find them HERE. Long Live The Z!

 




TUNING: Kevin’s 2013 Nismo 370Z

Filed under: 370z,Featured Cars and Projects,Maintenance,Performance
by Alvin G @ 5:10 pm on December 27, 2021

 

Kevin M visited Z Car Garage for Stillen intakes, test pipes and dyno tuning on his 2013 Nismo 370Z.

 

He found this V1 Nismo Z34 in September 2020 at a Nissan dealership that was not yet advertised. Being a rare Magma Red model he jumped on it quickly.

 

A common issue on the 370Z is the internal slave failing due to heat. Thankfully Z Speed Performance makes a kit to convert the internal slave to external (CMAK Upgrade). In January 2021 on his first to ZCG we performed the CMAK upgrade. Since the transmission was removed Kevin opted for a Z Speed Stage 1 Quiet clutch with steel flywheel:

“When I first got the Nismo I was worried about the infamous csc going out. So I looked up for any shops that dealt strictly with Nissan and I was lucky enough to come across Z Car Garage. Transmission work included the Zspeed Performance Stage one quiet clutch kit with C MAK. My Nismo felt almost brand new compared to when I drove it off the dealership.” 

 

 
 

We also installed Whiteline diff bushings on that first visit and discussed doing a tune and some hot rod stuff in the future.

 

In October 2021 Kevin returned to ZCG. We installed CWorks Test Pipes and Stillen GEN 3 intakes:

 

Dyno Tuning

 

We specialize in UPREV and EcuTek Tuning to maximize power gains from individual modifications like intake and exhaust upgrades. Rob UPREV flashed Kevin’s Z with the additional ARC license. Baseline power was 296hp/256tq and after tuning it made 338hp/275tq at the wheels, gains of 42hp/19tq. Kevin was happy with the power improvements.

Enjoy this video with dyno runs and exhaust system sounds!

 

Thanks for your support Kevin, Long Live The Z!
