Tetsuya has been with ZCG for many years and came back again this time for some exhaust headers and ART test pipes. You can see the TEIN suspension, VOLK wheels and Bassani exhaust modifications from previous visits in the following posts:

To complete the exhaust upgrades we installed DC headers and Motordyne ART pipes. Stock parts below, left:

 

Installed:

 

To maximize the gains from the new exhaust we UPREV tuned with nice results:

 

Starting with a baseline of 248hp/242tq, the headers, exhaust and tuning yielded 260hp/252tq to the wheels with strongs gains from 2000rpm to redline.  Enjoy The Ride, Tetsuya and thank you for your continued support!

 

Ron L came to Z Car Garage from a dealership referral and we installed a full Stillen supercharger kit on his 2013 Nismo 370z.

Stillen’s kit offers VQ37 owners 400whp and full CARB compliance—it’s extremely popular with ZCG customers and we have performed numerous installs over the years. Here is Ron’s polished setup:

 

The install went smoothly and we added a Stillen 25-row oil cooler and GT-R spark plugs:

 

Yes, we miss that OEM Nismo red intake cover but the Stillen intake is equally pretty and still fits under the NISMO strut tower brace!

 

On the dyno a CAN tune with ZCG touches nets a satisfying +132hp/70tq gain for a total of 436hp/323tq at the wheels:

 

Icing on the cake is that next time Ron pulls beside a police officer he will be cool as a cucumber knowing his 500hp Nismo Z is 50-state emissions legal 🙂 Enjoy The Boosted Ride, Ron!

 

 

James L is from San Francisco and visited ZCG to get Stillen intakes and an UPREV tune. This is one of the first Q60’s we had our hands on:

 

The Gen3 intake installation is straightforward:

 

Before/after

 

UPREV dyno tuning time! Baseline numbers for this 2013 Q60 were 295hp/253 to the wheels:

 

The intakes add +6hp peak hp:

 

UPREV tuning however optimizes both power/torque curves with gains throughout the rev range.Total power is now 308hp/256tq to the wheels:

 

 

If you are a fan of vintage racing come out to Laguna Seca August 13-16 for the Rolex Monterey Motorsports Reunion. ZCG is hosting a VIP Car Corral for your Nissan/Datsun/Infiniti. To park in the corral you MUST purchase the corral tickets through ZCG! It is only $10, allows you to park with other Datsun owners, and it’s literally footsteps away from the track and venue, unlike general parking. See you there!

Pictures from last year’s event are HERE

 

Richard M visited ZCG earlier this year for an UPREV tune on his 2009 370z. We made great NA power with the tune but boost was beckoning so 3k miles later Richard came back for a full Stillen supercharger installation.

 

We added a Stillen 25-row oil cooler and GTR plugs:

 

The kit comes together seamlessly, before/after:

 

How does it perform? With a CAN tune out of the box we saw 376hp/284tq to the wheels. This wasn’t terribly impressive considering baseline NA numbers were 305hp/251tq, netting gains of 69hp/33tq:

After Rob’s custom tune we squeezed another 58hp/55tq for a total of 433hp/339tq to the wheels. The gains are significant all the way to the VQ’s sweet 7500rpm redline, even with slightly less boost!

 

Richard should be happier now with over 400whp 🙂
