We love to hear about Datsuns that stay in the family. Geri R has been a long time customer with Z Car Garage and we performed a full OEM suspension rebuild(plus many other items) on her Datsun 260z.

After 30+ years of ownership, Geri decided to sell her Z and Scott W is the lucky new owner. Here are a few before/after pics of the suspension refresh with freshly powdercoated a-arms, T/C rods, subframes, zinc’d hardware… so clean!

 

 

After taking a ride in Lou’s RHD FairladyZ, Scott wants to add full coil-overs, triple-carbs, the ZCG throttle cable mod, and Panasport C8 wheels:

 

We are excited to see the next chapter in this 260’z life with a new home!

 

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!

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!
