Sitting Pretty: Rich’s G37 Sport Coupe

Filed under: 370z,Featured Cars and Projects,Performance
by Alvin G @ 7:07 pm on June 27, 2017

 

We met Rich G when he called us about the suspension on his 2011 G37 Sport Coupe.  After visiting a wheel shop to get new wheels/tires installed he reported the car was bottoming out and felt very unstable. Rich sought out a specialist (sound familiar?), called ZCG and met with Rob to assess the car. We put the G up on the rack and noticed installation of very aggressive H&R lowering springs. The springs and aggressive wheel/tire fitment made the car bottom out and also cause excessive camber wear.

 

We immediately changed the springs to a set of Eibach progressive rate units which are fantastic for a car that just wants to be slightly lower and enjoyed as a daily driver.

 
 

The wheels were wrapped in new Hankook v12 evo S2 tires and SPC  F/R control arms help keep the suspension properly aligned. The G still has a nice stance:

 

Rich’s son is a younger fellow and removed the rear muffler so we put it back on for Rich. If you are going to wear tires like an adult sports car…it might as well sound like one too:) After the G was sorted we heard from Rich a few weeks later and he was super stoked with the way the car rides.  He was also happy to report perfect tire wear too.

 
 

So here we have another great example of the specialty shop working for you! Enjoy The Ride, Rich!




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:

Phan Cam 71016 051 Phan Cam 71016 001
 

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!
