We love to install bolt-on parts that add power to your Z/G car. At Z Car Garage UPREV tuning can maximize power gains from individual modifications like intake/exhaust upgrades. Here are two examples of how we consistently achieve better performance through tuning, with mods or even without!

Mike F is a long time friend of ZCG and owner of a very cool 700hp Fox-body Mustang. His daily driver and family-unit vehicle is this G35 S sedan and Mikey want to give it a little more oomph.

 

We installed Berk high-flow cats followed by an UPREV tune.  The automatic-equipped G gained 18hp/11tq for a grand total of 277hp/249tq to the wheels. Another significant benefit of tuning: the VQ can now rev all the way to it’s sweet 7500rpm redline!

 

Scott A’s Nismo 370z is a great example of UPREV tuning improving power/delivery without any bolt-on mods.

 

With tuning the Z is now past that magic 300whp mark at 314hp/262tq to the wheels. Great all-around gains in torque with significant mid-to-high range gains in horsepower…just from the UPREV!

 

At the shop we love to install performance parts but we too can appreciate aesthetic improvements as well. Tim D came in for a rear fog light install. As most 370z owners know, all non-US spec Zs came with a functional, red fog light just below the rear license plate area. US-spec cars however have a “blank” piece in place here but thanks to the aftermarket there are kits available to restore this item.

After proper wiring this “smoked” rear lamp is now functional!

 

The neat part about this kit is that the light can be tied into the brake, flasher, and turn signals with or without a switch. Got a cosmetic part that needs installation? Let us know if we can help!

 

Matt found Z Car Garage by referral from a local car wash. He had installed a few bolt-ons and needed a tune so we UPREV’d his 370z. Baseline numbers were 294hp/238tq and after tuning 309hp/253tq:

 

The dyno shows significant gains in hp and tq throughout the entire rev range. We are big fans of UPREV tuning and it consistently works well when optimizing individual mods. We will have more examples this week on both NA and FI cars so stay tuned!

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!
