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!

 

 




Jason’s Stillen Supercharged 370z

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!

 




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:

Mike’s Vortech Supercharged 350z

Filed under: Featured Cars and Projects,Maintenance,Performance

Mike W has been a Z Car Garage customer for many years and he decided it was time to go forced induction on his 350z with a Vortech supercharger kit. It is very important at ZCG to offer packages that are proven and a customer can count on us to do the homework for them. All they need to to is enjoy the ride…

 

We installed a V3 supercharger kit with JWT S1 cams, Bosch EV14 1000cc injectors, Aeromotive 340 fuel pump, DC Sports headers, ART pipes, and Stillen oil cooler:

 

 

We also added a few ZCG refinements including our cold air intake kit,  silencer bypass (quiets the race gate from Vortech), and a ZCG heat shield to protect fuel lines from header heat.

 

On the dyno we UPREV tuned using a GT MAF and saw gains of 169hp/98tq for a total of 419hp/341tq to the wheels:

 

Even though Mike’s Z is a 2003 it only has 30,000 miles!  While the car was at the shop we performed 30k services including replacement of all fluids, drive belts and going over the entire suspension and brakes. We also performed a fender roll:

  
 

DEFI gauges were installed in the dash:

 
 

Mike wanted us to take care of a few things that were bothering him like a failed passenger side window motor. This is common in Z/G35s and we have fixed it many times. Thanks for letting us work on your Daytona Blue Z33 Mike. Volk SF Challenges are sweet.  Enjoy The Boost!

 

 

 




400whp Sleeper: Paul’s Vortech Supercharged G35

Filed under: Featured Cars and Projects,Performance

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:
