Danny K. owns this slick G35 coupe sitting on one of my favorite wheels, the Volk SF Challenge. He had a Vortech supercharger kit installed by a local performance shop and unfortunately the car wasn’t running right. We discovered a vacuum leak at the injector rail and fixed a few other items.
The G now runs as it should and the dyno reveals a healthy drivetrain. With 398hp/331tq to the wheels we are confident that Danny is happier now:)

Daren S. wanted to make his Infiniti G35 Journey Sedan more exciting to drive on the commute. Better breathing can improve power so we bolted on JWT dual POP chargers and a Stillen exhaust system followed by UPREV tuning.
The POP chargers also add a very throaty intake sound 🙂
The Stillen exhaust system replaces the restrictive OEM parts and makes getting on the throttle a bit more satisfying:
On the dyno, the intake alone made a noticeable improvement in power from 260hp/235tq to 264hp/243tq at the wheels:
UPREV tuning makes efficient use of these breathing mods for a final output of 276hp/246tq! Gotta love that huge gain under both hp/tq curves:
Whoa is just as important as go and there are many options out there for improving braking performance. Instead of a full-blown big-brake kit Daren opted for a Stoptech Sport Kit:
This is a great alternative to OEM parts. When coupled with our favorite 309 pad and Stoptech 600 fluid this kit is perfect for spirited driving whether it be on your favorite mountain road or commute!

Tung N. is an auto technician at a local shop and the owner of this beautiful 370z. Tung did a very clean installation of bolt-ons himself and came to ZCG for tuning. We are glad to see that he still enjoys working on cars as a hobby!
On the dyno Rob’s UPREV tuning yielded gains of 10hp/6tq for a total of 295hp/253tq at the wheels. Power delivery was improved throughout the rev range:

Hideki K brought his ultra-nice Nismo Z33 in for a full Stillen supercharger installation. Unfortunately Stillen did not make a kit specifically for the Nismo edition Z so we purchased a Stillen kit designed for the standard HR motor and made it work for Hideki!
Here are the goodies:
A few shots of the install:
From NA to Forced Induction:
On the dyno the Nismo put down 282hp/246tq and the Stillen kit bumped those figures up to 370hp/272tq to the wheels:
Rob’s tuning yielded significant gains of 22hp/13tq for a grand total of 392hp/285tq to the wheels!
Enjoy the Ride Hideki!
