Greg S came to Z Car Garage for some bolt-ons on his HR-powered 350z.  We installed JWT dual pop chargers and a Bassani cat-back exhaust:

 

Intakes before/after:

Bassani exhaust:

 

Let’s take a look at what the bolt-ons do on the dyno. Starting with a baseline of 253hp/223tq the JWT intakes alone slightly increase peak hp/tq, with significant mid and upper rev range gains:

 

Adding the Bassani exhaust yielded greater gains throughout the rev range, netting +8hp/6tq over baseline:

 

An UPREV tune further optimizes these bolt-ons. Look at the huge low to mid-range gains of over 20hp/20tq! Peak numbers are 264hp/246tw to the wheels, a +11hp/23tq improvement over baseline with more power everywhere!

Enjoy the newfound power and sound Greg!

 

Josh R called us up for some free Z Car Garage swag.  Rob happily sent out a few things but they never reached Josh. This was unacceptable so Rob sent him a care package with key chains, shirts, lanyards and ensured delivery with the boys in brown.

 

Josh got finally got his swag and mentioned that he’d be back with his Z33 if he needed some tuning and we are happy to report that we worked on his Z recently!  We installed ART pipes, Motordyne MREV manifold /plenum spacer and finished the bolt-ons off with an UPREV tune.
Here are the ART pipes in place of the factory cats:

Before/after:

On the dyno we started with a baseline of 227hp/215tq and after bolt-on/tuning ended up with 254hp/233tq to the wheels:

Here is a breakdown of the bolt-ons and UPREV tuning.

Baseline to plenum spacer/manifold shows slight peak gains but significantly more midrange power:

 

UPREV tuning maximizes these bolt-ons yielding +6hp/7tq. Also note the increased rev limit:

 

The ART pipes really help in upper rev range increasing hp by 12hp. A final UPREV tuning session adds even more hp/tq:

Thank you Josh for coming to ZCG!

 

David Q is a new customer and came to Z Car Garage for some bolt-ons on his 370z.  We installed a Berk cat-back exhaust:

 

Stillen intakes and Motordyne M370z intake manifold:

On the dyno the motor dyne intake increased mid to upper rev range torque:

With the Berk exhaust and UPREV tuning even more low and high rpm hp/tq gains were seen:

Final results of 308hp/263tq to the wheels are improvements of +6hp/18tq. More importantly than peak gains, check out the significant gains in hp/tq from 3krpm all the way to redline where the Z makes almost +25hp/tq!

 

James Z (seriously, “Z”!) is a new customer and came to Z Car Garage while searching for a shop to install all of his bolt-ons purchased through the web. We installed an ARK exhaust and Stillen intakes on his 2013 Z34:

Stillen Intakes:

 

To make the most from intake/exhaust additions Rob UPREV tuned the Z with gains of +15hp/8tq resulting in 315hp/258tq to the wheels. Note the flatter torque curve in addition to increased hp all the way to redline:

 

We also installed a personal touch to the interior with these lighted “Z” kick panels:

 

More power and an enjoyable sound…thanks for coming to ZCG James!

Tetsuya is a long time customer and visited ZCG years ago for an UPREV tune and Bassani exhaust system on his pretty 2005 350z. He recently came back for some suspension upgrades and we happily obliged. We installed TEIN StreetFlex coilovers combined with their latest EDFCactive dampening controller:

The StreetFlex dampeners are trick parts with pillowball mounts and 16-way adjustability. The
“active” EDFC offers two new features in addition to the totally redesigned interface. With the on-board accelerometer, dampening can be automatically adjusted based on g-loads and a GPS unit enables speed-sensitive adjustment!

 

The EDFC unit was mounted neatly in the Z’s NAV/cubby:

 

To handle braking duties we installed a Stoptech Big Brake Kit (332mm) finished in red up front and color matched the stock rear calipers on new Stoptech rotors. Everything is framed nicely behind the new Volk 57xtreme 19″ wheels:

Tetsuya’s Z is now a well-rounded sports car that will surely bring more smiles on spirited drives!
