Nick’s Vortech Supercharged G35

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 8:45 pm on March 27, 2017

 

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:

 
 

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!

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.

400whp Sleeper: Paul’s Vortech Supercharged G35

ZCG 41315 187
 

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:

Scott’s Vortech Supercharged G35

ZCG 61614 1 020

Scott C has been with Z Car Garage since our opening in 2004.  Over the years we have worked with Scott to build his G35 coupe into a formidable sportscar while maintaing its stock-ish looks. With 49k miles on his G35 he visited us in 2010 to discuss Forced Induction options.  We did a full Vortech supercharger installation with supporting mods including a Bassani cat-back exhaust system, JWT cams, headers, ZCG oil cooler and DEFI gauges.

Scott throughly enjoyed his boosted G for a year and in 2011 came back to us for a KarumaZ front fascia to allow more airflow to the intercooler. In 2014 Scott wanted more power so we built a low-compression VQ with forged internals and a host of speed parts. Here is the engine coming out and a few shots of the new internals:

We added 1000cc injectors, GT MAF, Aeromotive 340 fuel pump and a SI blower wheel upgrade:

With the built engine and supporting mods in place we UPREV tuned the G35 making 429hp/361tq to the wheels. Significant improvements over the stock-block based setup at 375hp/311tq for this automatic-equipped VQ:

With the added power upgrading the stock braking system naturally was a prudent idea.   Scott’s G was treated to a full Stoptech Big-Brake Kit up front using their 332mm rotors and ST-40 calipers in red. Rear brakes were upgraded with a Stoptech Sport Kit and OEM calipers were color matched. We love the 309 pads as they are a sweet compound for aggressive driving.

Thick, vented rotors and huge calipers help shed heat for repeated fade-free braking:

Rear calipers were color-matched and grab Stoptech rotors:

The new calipers look great behind the OEM wheels:

Finally, GT-spec braces add some rigidity to the chassis:

We are happy to see Scott’s G35 evolve into a well-rounded 400hp+ street sleeper, Enjoy The Ride!
