Nick’s Vortech Supercharged G35

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.

Motordyne exhaust:

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:

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!

Last year we helped Ruben enjoy the merits of boost with a full Vortech supercharger install install on his LeMans Sunset 350z:

The high-flow catalytic convertors had failed so we replaced them ART pipes from Motordyne:

Three For Thursday

Three for Thursday! Here are 3 owners that visited Z Car Garage for upgrades so they could Enjoy The Ride. Thomas C was experiencing brake fade/overheating with the Akebono caliper setup on his G37 Sedan. We installed a Stoptech Sport Kit with our favorite SS309 pads:

Slotted rotors also help shed heat, before/after shown below:

We also UPREV tuned the G now making 291hp/247tq to the wheels:

Rich M wanted firmer shifts from his automatic-equipped G37 Coupe. We installed a TransGo shift kit followed by UPREV tuning:

TransGO kit:

ZCG CAM 1 71314 025ZCG CAM 1 71314 027ZCG CAM 1 71314 029

The dyno plot reveals the benefits of UPREV tuning and the TransGo kit. Firmer shifts are evident by the absence of the “loop” (blue curves) seen with OEM automatic-equipped Z/Gs.  Huge peak gains of 20hp/18tq to the wheels and increased area under the curve everywhere means this is power you can feel!

Garth J brought his 2003 350z to us for Stoptech lines, 5/16″ plenum spacer and MREV2 lower intake, and new Bridgestone PP S-04 tires:

CAM 5 103114 013

With the intake mods and UPREV tuning Garth’s Z picked up 7hp/5tq to the wheels. More importantly are the mid-range and top-end gains:

How can we help you enjoy your Z or G?
