Dennis’ Infiniti G37

Filed under: 370z,Featured Cars and Projects,Performance
by Alvin G @ 6:05 am on October 16, 2017

 

Dennis K comes from the East coast and moved to Bay Area for work. Once here he wanted to find a specialty shop to help him with his G37. He already had coil-overs and larger wheels/tires but no camber adjustment. His first visit to ZCG in October ’16 included installation of SPC F/R cambers arms and new Bridgestone S-04s tires.

 

Following a full alignment we also raised his coil-overs slightly to cope with the wonderfully smooth roads we have here in the Bay Area. Finally we added our favorite sway bars from Hotchkis, and performed some cleanup work.  As always, the performance and modifying bug kicked in. Dennis came back to us in March of this year after he had waited for his Fast Intentions cat-back exhaust to arrive:

 

A Stoptech Sport-kit rounded out the chassis upgrades. After the cat-back was installed, we change the oil, and installed several parts that Dennis had purchased online including a strut bar, grille and CF diffuser:

Thank you for letting us work on your G, Dennis!




Allan’s FX35

Allan came to ZCG because he was getting a Check Engine light resulting in smog issues. We found that his catalytic converters were well passed their lifespan and decided to get a set of low-mileage cats for testing. While the FX was in the shop we installed some Fast Intentions high-flow cats:

 
 

The engine was treated to a Stillen intake, and UPREV tuning. Since this car is awd, Rob UPREV streetuned it.

 

Allan is super stoked and enjoying the FX. He’s also been coming in for regular services and we love keeping folks on the road!

 




More Power: Jared’s Vortech Supercharged 350z

We have been working on Jared C’s 350z since he purchased it. He absolutely loves this Z car but does not get to drive it all the time. So when the occasion arrives and he gets behind the wheel, this Z is driven hard.

 
 

Last time when we checked in on Jared’s 350z it was making above average power/tq both NA and with the Vortech. Recently Jared let us know that he was at a point in his life where he wanted to make as much power as possible. We happily obliged. In June of this year after passing a smog check we began the power upgrades, starting with the Garett 900 hp FMIC assembly:

 
 

We installed our ZCG cold-air intake:

 
 

Jared’s Z had been tuned for 91 octane and for the power levels he wanted this would be a limiting factor due to conservative timing.

 

We proceeded with a 100 octane tune and made 443hp/360tq at the wheels:

 

With more power we also wanted to ensure that rest of the car was safe and in good shape. We changed the oil and replaced the Vortech fluid. The Stoptech BBK from his last visit was a very wise upgrade!

Enjoy The Boost Jared!

 

 




Baby Godzilla Commuter: Gary’s Pulsar GTi-R

If you tuned in last time to Gary’s Pulsar GTi-R we increased the power with a downpipe and several bolt-on parts:

 
 

Gary has been commuting and enjoying the newfound power in the Pulsar, but now he wanted to take the “cush” out of the ride. After some research he located BC Racing coil-overs for the RNN14 stateside and visited us for the installation:

 

Here are the coil-overs installed, before/after for the front/rear:

 
 
 

A full alignment followed the coil-over installation and we set the ride height so it looked good and handled well. Gary is super stoked!

 

 

 






Jason S had his 2012 370z supercharged at a performance shop in the Sacramento area. He then tracked us down to install a smaller pulley and raise the boost level followed by UPREV tuning to replace the base CAN tune.


Once we got his car into the shop we realiZed there were several things to handle before increasing the power. First, it is important to put in a colder spark plug in a car with forced induction and we used our proven GT-R units. When going from 280whp to 400whp we wanted to make sure nothing was rubbing so the following items were addressed:

All vacuum and boost lines were secured to keep them from popping off:

 
 

We corrected wiring at the ART pipes where a wire was touching the exhaust:

 
 

We corrected orientation of MAF housing:

   
 

The oil cooler lines were secured to prevent from rubbing anything on the front end:

 
 

We rectified the flaky wiring to the intercooler pump that allows water to flow into the cooler. No more on/off issues with the pump. With all of the clean-up work sorted we installed the smaller supercharger pulley and UPREV tuned the Z:

 
 

ZCG has performed many Stillen s/c kits and it’s a wonderful way to pump up your Z with minimal hassle and great power gains. Thank you Jason for letting us sort out your Z!
