Alex T is the owner of this pretty Black Cherry Z34 and he visited Z Car Garage on referral from our boost junkie friend and customer Juan F.  To satisfy Alex’s desire for forced induction we installed a Stillen supercharger kit that was actually used on Grant K’s Nismo 370z.

 

Out of the box, this older Stillen kit left plenty of room for improvement so we invested in several upgrades like 1000cc injectors, Aeromotive high-flow fuel pump, pulley and these engine oil/automatic transmission coolers:

 

The transmission received a GTM valve-body upgrade and stock bypass valve was replaced with a blow-off valve:

 

Fast Intentions test pipes replace factory cats:

 

To put the power down more effectively we installed a Quaife limited-slip differential, using the stock 3.36 R&P:

 

With all of the modifications and UPREV tuning Rob extracted 435hp/343tq to the wheels. This is a 147hp/104tq gain over stock:

 

To monitor vitals Alex chose PLX Device’s OBD2 multi-gauge. We first installed this trick, wireless sensor/gauge package on Steve’s G35 with an iPhone interface.  For Alex’s Z34 the multi-gauge was seamlessly integrated into the OEM pod:

We love the brilliant display and wealth of data that can be accessed:

 

Enjoy the Ride Alex!

Mike U visted Z Car Garage back in May for Stillen intakes on his Nismo 370z. The Z was a gift to himself and with just 2800 miles on the odometer he got the modification bug. In addition to the intakes we installed a Fast Intentions exhaust system and Eibach springs:

 

Exhaust before/after:

 

A few more shots of the system:

 

The Fast Intentions system looks great and also frees up some power!

 

We saw a 7hp peak gain at the wheels over baseline:

 

With Rob’s UPREV tuning Mike’s Z34 now makes 315hp/256tq:

 

Eibach springs improve the stance and SPC camber arms keeping the alignment in check:

  

We dig the slight ride height reduction:

 

Enjoy The Ride, Mike!

 

Thomas C came in for full 60k mile services and a new exhaust system on his G37 S sedan.

 

The old exhaust system had an aftermarket y-pipe that didn’t significantly increase power. We installed a full cat-back system from Fast Intentions followed by an UPREV tune. Old vs new:

 

The new exhaust looks and sounds great:

 

On the dyno we were impressed with gains from the FI exhaust combined with UPREV tuning. Peak numbers were 302hp/249tq to the wheels, an increase of +15hp/10tq. Check out the mid-range tp redline gains in both hp and tq from 3500rpm:

 

 

We worked on Dannie P’s Infiniti FX35 last year adding GTSpec bracing and a custom Bassani exhaust system. Dannie came back to ZCG recently for more mods. We installed additional bracing from Summit/GTspec and Fast Intentions resonated high-flow cats (HFCs) followed by on-road tuning.

 

Here is the front crossmember brace:

 

HFCs, in place of stock cats (L):

 

We did on-road tuning to make sure the A/F and timing were safe. Enjoy The Ride Dannie!

 

Joe R was referred to Z Car Garage by long-time customer and Z33 owner “T.C”. Joe’s 2013 370z came to us with just 1900 miles on the odometer ready for some bolt-ons!  We installed Fast Intentions Hi-Flow cats, their TDX exhaust system and Stillen intakes:

 

Stillen Gen3 intakes:

 

Hi-flow cats from Fast Intentions:

 

The TDX cat-back exhaust compared to stock:

 

UPREV tuning yields 311hp/250tq to the wheels:

 

We think making the rear diffuser black is a must have for any 370z and William’s has been doing this mod for the front (pre-2013) and rear since the Z34 was released:
