Nick K has been coming to Z Car Garage for several years. He makes the trek all the way from Sacramento and we’re proud to be the only shop that gets to work on his 2004 G35 Coupe. In 2012 we first met Nick, UPREV flashed his car and performed routine services. He had daydreamed of one day doing a supercharger kit.
A year later Nick K’s engine was tired. With 209k miles on the clock he dropped the G35 off at ZCG in preparation for a fresh start and…boost! We removed the ailing VQ35 engine and installed a complete VQ35 from a customer who wrecked his car with 50k miles on it:
With the engine out it was prudent to install a JWT HD clutch/aluminum flywheel. We did a Vortech tuner supercharger kit using our recipe of 1000cc injectors, GT MAF, and Aeromotive 340 fuel pump. To keep everything cool in Sactown heat we installed a 25-row oil cooler. In 2013, Nick was on his way with a new engine and boost, enjoying a nice 140hp/105tq bump in power for a total of 386hp/334tq to the wheels:
Gustavo L has been bringing his 2004 Infiniti G35 Coupe for bolt-ons the last few years. His first visit was for a Motordyne plenum spacer and UPREV tune. Last May, Gustavo came back to ZCG with a plan for more new parts including a full exhaust system, ART pipes, 60k service and a TransGO shift kit.
Firmer shifts on this automatic with the shift kit:

We performed a re-tune with UPREV and saw gains of 19hp/10tq for a total of 247hp/233tq to the wheels. Power is increased throughout the entire rev band:
Gustavo brings his car from Watsonville which is a bit of a hike but totally worth it for the power of ZCG! He is stoked and Enjoying The Ride!
Jimmy V came to Z Car Garage with his 2012 Infiniti G37 Sedan, aptly named the “GNTLMN Z”. Jimmy and Rob discussed options for the best exhaust system, tuning and suspension. We got him dialed in with a Fast Intentions cat-back exhaust system using 18″ resonators and 2.5″ piping, Motordyne ART pipes, and Hotchkis sway bars:

Jimmy wanted to see dyno results before/after with no tuning at this time. With Stillen Gen3 intakes already installed we baselined at 301hp/250tq and 315hp/256tq to the wheels with the new exhaust components:
You can watch a video of the dyno run (and see more pictures) of Jimmy’s G on his Instagram account linked below:
Here are the Hotchkis bars installed, front stock(Left):
We also installed a new battery in his key fob and GNTLMN Z was off to Enjoy The Ride. Thanks for coming to ZCG Jimmy, and we like how your G has progressed!
Daniel M came to ZCG to add a few touches to his commuter: a 2007 Infiniti G35 sedan. With 69k on the clock we installed a Stillen Gen. 2 cat-back exhaust system, UPREV tuning and Hotchkis sway bars.
Before/after of the Stillen cat-back exhaust system:
The exhsust looks and sounds great:
UPREV tuning yielded gains of 9hp/7tq to the wheels:
Enjoy The Commute, Daniel!
Paul S owns a smog shop in South San Francisco and contacted us about making his Infiniti G35 a “sleeper”. You know, the kind of car that looks very stock from the outside but gets down like the “other” high-hp cars coming out of Z Car Garage. We discussed options for forced induction and decided on a Vortech supercharger–making good power and having CARB legal status was very attractive.
The VQ had 98k miles and to prepare for boost we performed some preventative maintenance including a thermostat change. The Vortech kit was the V3 model which is self-lubricating and polished:
We installed a JWT HD Clutch and Flywheel:
