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:

More 370z reports on the way! Greg J is a new customer at ZCG and visited ZCG for Stillen Gen 3 intakes, Bassani exhaust and an UPREV tune on his Z34 Roadster.

The VQ responded well to the bolt-on mods with gains of 24hp/11tq to for a total of 307hp/248tq to the wheels:

Marc H found Z Car Garage online and wanted to see what we were all about. After visiting the shop he dropped off his ultra-clean, low mileage 2008 350z for power and suspension goodies:

We love the HR engine found in the latest Z33s because they respond extremely well to simple bolt-ons and UPREV tuning. We started with a with Bassani cat-back exhaust followed by JWT dual POP charger intakes :

On the dyno, Marc’s 350z baselined at 271hp/245tq to the wheels.  The Bassani exhaust netted a peak gain of 7hp and significant midrange gains in torque:

The JWT intakes added an additional 4hp:

This graph illustrates the benefit of UPREV tuning when adding bolt-ons. More power everywhere, all the way up to 7500rpm for peak gains of 19hp/8tq for a total of 290hp/253tq to the wheels:

Mark H Start to Finish
 

Marc wanted to improve handling and braking so we installed Eibach springs, Hotchkis sway bars, and Whiteline T/C rod bushings followed by a full alignment. Factory Brembo brakes were upgraded with Stoptech Sport Kits all around:

Marc was very pleased with the results and has been enjoying his Z.  He told us he would be coming back to ZCG and we will happily oblige!

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.

OEM vs Stoptech up front:

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!

Alfredo’s Z33

Alfredo D is a new customer that met us on the ZONC Canepa Design fun run in 2013. After visiting Z Car Garage he wanted to improve the fun factor on his Z33 roadster with bolt-ons. We gave him the ZCG essentials: Bassani exhaust, JWT POP charger, Eibach springs and control arms.

We know the OEM exhaust system on a 350z is mellifluous…few can mistake that undeniable VQ-burble. Why not accentuate that sound and gain a few hp in the process? The Bassani cat-back exhaust system is one of the best no-compromise setups available!

The JWT intake helps with breathing and gives a nice growl under throttle:

Firming up the Z’s handling are Eibach springs and SPC adjustable control arms. Full alignment follows.
