Matt M is another member of the Inconceivable Racing group and visited ZCG to supercharge his 370z Convertible. Here are a few pictures of the Stillen kit installation:

Matt came back to have us install some ART pipes and a Fast Intentions catback exhaust system:

ART pipes in place:

Being base model Z, Matt wanted to put slightly wider wheels on and sticky RE-71R tires for track days:

We love the PLX Devices gauge that neatly replaces the clock with a multi-function display to monitor vitals:

 

Finally, also installed new end links for his sway bars:

On the dyno we retuned with ECUTEK to maximize gains from the bolt-ons. Final numbers are 402hp/354tq to the wheels, peak gains of 32hp/24tq. After 4000rpm gains of almost +50hp/tq are seen:

Eric T hails from Benicia, CA and he is one of the key members of Inconceivable Racing along with our customers Matt M and Rasheed B. This is a group of enthusiasts that got into Z cars and are now obsessed with taking them to open track days and events like Shift Sector. What is really cool is that both Eric and his wife run their HR-powered 350z cars together at the track!

Here are the couple enjoy their Z cars at Laguna Seca. It is a small Z-car world and we have worked on Eric’s wife’s 350z Convertible because it was our man William’s!

Eric had been to several independent shops and wasn’t really happy.  Rasheed told him about ZCG and we met with Eric to help sort his Z.  After driving at Laguna Seca, he was frustrated with corner entry and exit speeds. This was a result of not putting power down effectively through the open differential on his Base-model Z. Our solution was to install the OS Giken limited-slip unit:

Here is the unit being installed with a 4.08 gear, all new bearings and seals.  We also added a NISMO Diff cover:

 

  

The diff all buttoned-up and installed on the car:

  

With the car up on the lift we noticed one of the bushings in rear subframe was leaking. The subframe was pulled and all bushings were replaced with with SPL solid bushings. The diff received Whiteline bushings:

    

The aftermarket exhaust system was rubbing on the rear chassis brace and had a rubber pad wedged in between as the solution from a previous shop. We fixed it:

The exhaust was also rubbing on the rear sway bar, where a heater hose complete with hose clamps was used as an isolator. We fixed this well:

Motordyne ART pipes were installed and the Z was retuned with UPREV:

On the dyno we found peak gains of 7hp/11tq for a final 303hp/265tq to the wheels. More importantly the gains can be seen throughout the rev range:

After we performed this work Eric attended a 2-day race event at ‘Seca for his birthday. He was super pumped with the Z and it performed well. He’s a ZCG believer. Enjoy the Ride, Eric!

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!

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:

You can watch a video of the dyno run (and see more pictures) of Jimmy’s G on his Instagram account linked below:

Here are the Hotchkis bars installed, front stock(Left):

 

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!
