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:

Daniel M came to ZCG to add a few touches to his commuter: a 2007 Infiniti G35 sedan. With 69k on the clock we installed a Stillen Gen. 2 cat-back exhaust system, UPREV tuning and Hotchkis sway bars.

 

 

Before/after of the Stillen cat-back exhaust system:

 

The exhsust looks and sounds great:

 

UPREV tuning yielded gains of 9hp/7tq to the wheels:

 

Enjoy The Commute, Daniel!

 

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!

 

 

Joey T’s Infiniti Q60 gained 18hp/11tq with UPREV tuning for a total of 323hp/267tq to the wheels. Note the increase in power and torque from 2500rpm to redline:

 

 

 

Dax S’ 370z picked up 14hp/8tq for a total of 315hp/255tq to the wheels. More importantly is the power delivery with gains throughout the entire rev range:

 

 

In 2012 Jack W was visiting the SF Bay Area on his way down from Canada. He heard about Z Car Garage and stopped by for UPREV tuning on his Z34 Roadster. We also discussed the possibility of force-induction via GTM’s newly developed (at the time) TD05 16g twin-turbo kit. The following year Jack crossed the border once more to visit ZCG and make the commitment to boost! We installed a GTM Stage 2  TT kit with their supporting parts including a 25-row engine oil cooler, automatic transmission cooler and valve body upgrade.

GTM manifold details:

Final installation looks ultra clean and very subtle:

On the dyno the GTM Stage 2 kit produced 434hp/360tq to the wheels:

 

Jack’s Z was one of our first cars to receive the PLX Devices gauges which became popular on later builds.

 

We mounted the PLX DM-100 in the factory clock gauge-pod location:

 

We installed camber arms to complement existing coil-overs and after we performed 50 miles of test driving Jack flew down to SJC and drove back to Canada in his boosted beauty.

13k miles later we are happy to report that Jack’s GTM-powered 370z has been running flawlessly. He came back to ZCG to do a full inspection, oil change and a re-tune:

 

With 455hp/379tq to the wheels Jack Enjoyed The Roadtrip back to Canada, another happy ZCG international customer!

Marc H found Z Car Garage online and wanted to see what we were all about. After visiting the shop he dropped off his ultra-clean, low mileage 2008 350z for power and suspension goodies:

 

We love the HR engine found in the latest Z33s because they respond extremely well to simple bolt-ons and UPREV tuning. We started with a with Bassani cat-back exhaust followed by JWT dual POP charger intakes :

 

On the dyno, Marc’s 350z baselined at 271hp/245tq to the wheels.  The Bassani exhaust netted a peak gain of 7hp and significant midrange gains in torque:

The JWT intakes added an additional 4hp:

 

This graph illustrates the benefit of UPREV tuning when adding bolt-ons. More power everywhere, all the way up to 7500rpm for peak gains of 19hp/8tq for a total of 290hp/253tq to the wheels:

 

Marc wanted to improve handling and braking so we installed Eibach springs, Hotchkis sway bars, and Whiteline T/C rod bushings followed by a full alignment. Factory Brembo brakes were upgraded with Stoptech Sport Kits all around:

 

Sway bars:

 

Marc was very pleased with the results and has been enjoying his Z.  He told us he would be coming back to ZCG and we will happily oblige!
