Since its introduction we have been impressed with how well the 370z’s VQ37 responds to simple bolt-on modifications. Steven L’s Solid Red Z34 made some great power gains with intakes, exhaust, pulleys and an UPREV tune from Rob.

Shown above are the Stillen Gen 3 dual intakes, Stillen exhaust system and pulleys.

Before/after with the Stillen exhaust system.

Stillen intakes before/after.  We dyno’d the car before the mods, after and also with the tuning…

With just the bolt-ons Steven’s Z picked up 23hp/9tq to the wheels with gains throughout the entire rev range. Icing on the cake: Rob’s UPREV tuning squeezed even more hp/tq for a grand total of 315hp/251tq!

The Nissan 300zx Twin Turbo came from the factory with a very potent powerplant capable of doubling its output in modified form. Unfortunately the Z32 also came from the factory with brakes that were just adequate even at stock power levels. Once you turn up the boost, a car as massive as the Z needs some “whoa” to reign in the “go”…Stoptech to the rescue!

Patrick S recently purchased this ultra clean 60K! mile Z32 from Socal. It already had Stage 3 power and suspension upgrades and needed some big-brakes to acheive that all-important goal of having a perfectly balanced sportscar.  A Stoptech BBK up front with new rotors in back and  a new master cylinder were installed by ZCG:

The rear calipers were treated to “Stoptech red” finish to match the new front calipers:

The finished install:

How gorgeous are these SSRs? Patrick’s Z is now equally competent in the acceleration, handling and now braking departments!

Rob has UPREV tuned many cars and it’s no secret that with proper tuning, simple bolt-ons can yield significant power gains. David T. came to ZCG for a Bassani exhaust and tuning for his Z33 and left with some impressive results. The dyno chart shows a large improvement in peak hp and tq(+14hp/+20tq) at the wheels. Look closer however and you can see even more gains throughout the entire rev range.  At 3700rpm David’s Z makes 21hp more and enjoys a HUGE jump in torque from 215 to 245!

So make the most out of your bolt-ons and run more efficiently with some UPREV tuning at ZCG!

 

Nissan Z owners are dedicated to their cars. At ZCG we offer that same level of dedication to helping each customer achieve their vision of Z perfection. Tom N is the owner of this brilliant blue 370z and shows us how perseverance and love for the Z always prevails.
It begins just over 2 years ago when Tom visited ZCG for some simple NA bolt-ons that yielded over 300rwhp:

 

With significant power gains Tom then gave the Z a stance adjustment, stiffer suspension and a new look that soon became a “must do” for most Z34 owners: William’s “Blackout” package.

All of you can see where this is going, right? Time for BOOST! Two years ago the forced-induction scene for the Z34 was definitely not as abundant as for the Z33. Stillen offered a centrifugal-based supercharger and the only CARB-legal s/c kit on the market which was very attractive to Tom. ZCG installed the kit and put the Z on the dyno for some tuning only to find that it was not producing power as advertised by Stillen:

 

 

387hp/310tq at the wheels just didn’t feel or sound right. Despite Tom and ZCG’s best efforts, dealing with Stillen unfortunately did not yield an improvement which was disappointing. This is where the power of the Z and their owners comes into play.  Where most would be tempted to throw in the towel Tom kept at it and continued his quest for boost. Sam at GTM had developed a new Rotrex-based supercharger kit for the Z34 and it really impressed Rob.  GTM to the rescue!

Here are a few pics of the install. Note how compact the Rotrex unit is, FMIC detailing, and intakes:

 

Fit and finish of the kit is great and it really does have a sleeper look underhood with the Rotrex unit neatly tucked away. Do you see a blower? Looks like a power steering pump to me!

 

Tom also added a few supporting mods like Motordyne ART pipes and a Berk exhaust system.  Icing on the cake: The HKS camp2 engine monitoring system in the factory NAV location…

 

Did I mention that Tom has great taste? A subtle front lip and supremely tasty Volk TE37s finished in black with Bridgestone PP S-04 tires make this boosted 370z really special.

 

So how did the GTM kit perform compared to the Stillen?

 

With 421hp and 359tq at the wheels and more power all the way to that sweet HR-7500rpm redline, we think Tom is much happier with the GTM kit 🙂
