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!

 

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 🙂

At Z Car Garage we have had the pleasure of working with customers throughout California and the occasional out of state Z-Car fan that is willing to go the distance for that ZCG touch. How far would you drive to visit us? Jack W. drove his 370z roadster all the way from Canada! A roadtrip to San Francisco turned into an opportunity to arrive early and get the Z tuned…we happily obliged!

Jack’s Z34 came to us with a few bolt-on mods already in place like an Akrapovic exhaust system and dual intakes. ZCG installed a pulley and UPREV tuned for more power.

Thank you Jack for making ZCG Internationally known 🙂

Subtle aesthetic touches and performance mods make this a very special 370z. Here is Rob with the full story:

I met John M. in 2005 when he came down to ZCG to have some issues with his 350Z sorted out. He is from Folsom, Ca and makes the trek to ZCG each and every time he gets the itch to mod his Zed.  From 2005 to 2009 ZCG and John built a beautiful 350Z together with WORK wheels, Brembo brakes, Vortech supercharger and all the usual ZCG supporting mods like exhaust, cams, headers and Tein suspension. John transformed a stock Z to not only look good but also make great power and provide years of enjoyment.

 

When the GTR arrived in 2009 John made his way to a local dealer and made arrangements for his next purchase. At the last moment before commitment he stumbled into another part of the showroom and saw what would be his next Z. Realizing the limited aftermarket stuff for the R35 and the expense associated with mods a new direction was mapped out…

 

Gorgeous SSR Professor SP3 wheels with S04 tires look so right on the 370. Filling the spokes are Brembo brakes, 380mm 6 piston(front) and 345mm 4 piston(rear):

 

Killer handling and stance are taken care of by Tein coil-overs w/EDFC while Hotschkis sways and SPC F/R control arms complete the package:

 

Underhood mods include Injen dual intakes, Berk HFCs and exhaust system followed by an UPREV tune by Rob:

 

The stock Z34 has rather polarizing styling. You love it or hate it. We think a few low-key changes make the Z look sexier and who better to help achieve this than Williams Auto Body. Their “Blackout Package” includes the roof and front/rear bumper treatments. The result arguably is how Nissan should have released the 370!

 

The EDFC was mounted in the dash and a nice touch is the GT-R start button:

 

I am a huge GTR fan but after looking at John’s Z34 vision and seeing the end result I think this tag line is most appropriate…
“ Long live the Z”

Brad G. brought his silver Nismo 370z to ZCarGarage for high-flow cats and UPREV tuning. Below are the Berk Hi-Flow cats replacing the factory units.

The stock Nismo Z34 is rated at 350hp/276tq(flywheel) and on the ZCG dyno it produced 297hp/246tq at the wheels. The plot on the left compares this baseline run with the Berk HFCs installed and shows solid gains of 9hp/9tq. Rob UPREV tuned the Z and extracted even more power for a final output of 312hp/260tq at the wheels:

Stay tuned for more 370z action later this week!
