We have been working with Mike M and his 2006 Z33 since last year. With every visit to ZCG this 350z gets upgraded in both power and chassis areas. In November 2017, with 111k miles on the VQ a Vortech supercharger was installed with supporting mods:

   

Chassis improvements: KW V3 coil overs, SPC front/rear control arms, Hotchkis sway bars and a full alignment. We also installed ART pipes to replace the factory cats:

Mike’s latest visit to ZCG included fueling, gauges and more power upgrades. The fuel system was converted to support E85/ethanol starting with a Walbro 485 in-tank fuel pump:

 

Next, a CJ Motorsports Stage 2 fuel return system help keep up with the Walbro pump:

  

Increased fuel demands of E85 require larger fuel injectors so we installed IDX 1050CC units. A Zeitronix ethanol sensor is critical for monitoring E85 content:

  

The brains to managing the E85 content is a Haltech Platinum Pro plug-in. A PLX Devices dm6 AFR/gen4 gauge pod also accommodates the Zeitronix ethanol sensor readout:

  

Final power adder was a 2.87 pulley for the supercharger and our ZCG air bypass for the race gate:

 

From the dyno charts below, having the ability to change the ethanol content of fuel allows for more hp/torque.  More smiles per gallon as well with E85 currently at $1.99/gallon

(left) Baseline before Haltech tuning: 331hp/286tq and (right) baseline to 91 octane tune with Haltech: 346hp/303tq to the wheels

  

Final 91 octane tune with the Haltech: 364hp/306tq at the wheels:

 

75% Ethanol tune: 421hp/345tq to the wheels:

 

To balance an extra 126hp power from the Vortech we installed a Stoptech Big-Brake Kit. Up front are 332mm ST40 calipers in red, with slotted rotors:

The new brake also look great behind the Enkei RPF1 wheels:

 

Enjoy the Ride Mike!

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 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!
