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!

Mike F is a long time friend of ZCG and owner of a very cool 700hp Fox-body Mustang. His daily driver and family-unit vehicle is this G35 S sedan and Mikey want to give it a little more oomph.

 

We installed Berk high-flow cats followed by an UPREV tune.  The automatic-equipped G gained 18hp/11tq for a grand total of 277hp/249tq to the wheels. Another significant benefit of tuning: the VQ can now rev all the way to it’s sweet 7500rpm redline!

 

Scott A’s Nismo 370z is a great example of UPREV tuning improving power/delivery without any bolt-on mods.

 

With tuning the Z is now past that magic 300whp mark at 314hp/262tq to the wheels. Great all-around gains in torque with significant mid-to-high range gains in horsepower…just from the UPREV!

 

We enjoyed racing with Joel and his #49 IMSA Datsun 240z at the Rolex Motorsports Reunion in August. If you missed our coverage of the event please check it out HERE. When Mike Joy from FOX Sports visited us in the paddock and expressed interest in the Z and its history, we were flattered. Mike and camera crew did a very brief segment with the Z Car Garage team and it will be featured in their coverage of the race weekend!

Tune in to FOX Sports 1 this Saturday 10/11 at 10am (EST) to see their coverage and our brief moment in the spotlight 🙂

 

Long Live The Z!

 

 

 

George M built his Vortech-supercharged G35 coupe to participate in Hill Climb events while remaining an adept street car.  To ensure he could come back down the mountain we upgraded his brakes with a Stoptech big-brake kit:

 

Up front, the OEM Brembo calipers and rotors were replaced with Stoptech’s 380mm rotors 6-piston calipers:

At the rear, 355mm rotors and ST22 calipers. Note how everything still fit nicely behind the factory wheels:

 

Stay tuned as George will visit us later for power upgrades including a new MAF/injectors followed by dyno tuning.

 

 

Matt found Z Car Garage by referral from a local car wash. He had installed a few bolt-ons and needed a tune so we UPREV’d his 370z. Baseline numbers were 294hp/238tq and after tuning 309hp/253tq:

 

The dyno shows significant gains in hp and tq throughout the entire rev range. We are big fans of UPREV tuning and it consistently works well when optimizing individual mods. We will have more examples this week on both NA and FI cars so stay tuned!

 

Gilbert W wanted a CARB-legal solution for more power on his daily driven G37 sedan.  We’ve had great success with our past Stillen Supercharger builds and this forced-induction kit would be ideal for Gilbert’s needs.

 

Installation of the Stillen kit is straightforward. We use one-step colder GT-R spark plugs and a 19-row oil cooler:

Gilbert wanted improved handling without unnecessary harshness. The TEIN mono flex coil-over system with active EDFC allows on-board and speed-sensitive dampening adjustments! We installed a similar setup on Tetsuya’s 350z earlier this year. SPC F/R control arms were installed followed by a full alignment:

 

A relatively new item for Z/G owners is this trick adjustable clutch pedal box from RJM Performance. It offers improved driveability in terms of clutch-pedal engagement and that annoying shudder we’ve all experienced in Nissan’s Z/G manual transmissions:

 

The PLX Devices multi-gauges are becoming a popular method for monitoring engine vitals. Gilbert is using their Bluetooth “Kiwi” interface allowing display through smart phones. We did a neat install of this unit in Steve’s Vortech G35:

 

With the supercharger and exhaust in place we dyno tuned Gilbert’s G37. Baseline numbers were 283hp/241tq and it is now making 417hp/319tq to the wheels.  This is a gain of +134hp/78tq which once again shows how consistent power output has been with these kits!

Enjoy the Ride, Gilbert!
