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!

 

 

Arvy B had PPE long tube headers installed at another shop. From the pictures below you will see that these headers were installed with missing nuts and bolts and the pipes were touching the driver’s side underbody. It was unbearable to drive:

   

In the engine bay a factory fuel hose that went above passenger side had been replaced with a fuel vapor hose. This is dangerous as only a factory, high pressure fuel hose should be used:

Scott N visited ZCG because he felt the suspension on his 1994 Z32 ‘Vert could be improved.  The Z33 Rays wheels look sharp on this 300! We installed TEIN coil-overs and a few other goodies:

Here are the existing shocks and the new TEIN street coil-overs going in front and rear:

Z1 upper control arms:

 

SPL tension rods so we could fully adjust camber up front:

 

The rack bushings are vey common problem on z32s so we replaced them. In the back: the aftermarket adjustable upper control arms were making noise so we replaced them with OEM parts and performed a full alignment.

Scott is super happy and Enjoying The Ride!

 

 

 

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!

 

 

 

Our friend Patrick Chio has been racing his Nissan 350z competitively for several years and we’ve had the pleasure of helping him tune/maintain the car for events.  Last year he campaigned the Z in the USTCC (US Touring Car Championship series) with impressive results.

  

The final race of the season was a double header weekend at Thunderhill Raceway and Patrick won both! The last race on Sunday was won by just a bumper:

 

Congratulations Patrick we are proud of you!
