UPREV Tuning For Your Nissan

Filed under: 370z,Featured Cars and Projects,Performance
by Alvin G @ 3:56 pm on March 14, 2017


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!

 

Owen T had his 370z towed out of state for another tuner and he reached out to us for re-tune of an existing tune. The UPREV software is very user-friendly and a must-have for owners that have bolt-ons. Owen’s Z34 picked up 16hp/10tq for a total of 309hp/256tq to the wheels. Strong gains throughout the entire rev range:

ZCG 53015 014
 

Dan J is the owner of this gorgeous 2015 GT-R. The numbers are impressive: Zero to 60 mph in under three seconds; a top speed of 196 mph; 545 horsepower courtesy of a hand-built 3.8-liter twin-turbocharged V6 assembled in a clean room so high-tech that those fleeing scientists on the silver screen would kill to have one. This beast has also been finished in premium Regal Red paint embedded with 24-karat gold flakes! We think it is mesmerizing under varying light conditions:

Combined with an Ivory interior this R35 exudes a level of refinement and luxury not typically seen on earlier models:

Sidenote: I met Dan in December ’14 while helping his neighbor with a Datsun Roadster. Dan kindly let me park the 510 next his GT-R and I might have mentioned how we love them at ZCG ūüôā

So what does one do with such a beautiful sportscar? Add more power, of course! Dan came to us for a full AMS Alpha 7 package installation.

The package includes:

  • ALPHA front mount intercooler
  • COBB big SF intake pipe
  • Alpha 90mm Mid-pipe
  • Alpha 90mm Downpipes
  • HKS Legamax Exhaust System
  • Injector Dynamics 1000CC Injectors
  • Cobb AccessPORT V3

Let’s start with the exhaust and a closer look at the new mid-pipes and down pipes:

Underhood, better breathing is achieved through larger intakes and K&N air filters. Stealth black tubing is nice touch:

Rounding out intake mods is a larger Alpha front mount intercooler. It boasts 75% more internal flow area over stock and direct bolt-in/no cutting fitment! It doesn’t hurt to have the “Alpha” logo peeking through the front bumper too:

Fueling demands are met by larger 1000cc injectors:

How do all these mods add up to increase power? To find out we strapped the red beauty to the dyno:

ZCG 53015 027
 

Utilizing the CobbAccessPORT V3 for tuning we saw peak gains of 80hp/86tq for a total of 577hp/562tq to the wheels. The dyno plot reveals tremendous gains from 2500rpm to redline. For example at 4000rpm the GT-R is now making 560tq vs 460tq stock!

Dan’s GT-R was already blindingly quick from the factory and now it has even more power to enjoy while maintaining its Regal composure. Thank you for bringing your R35 to Z Car Garage! More pictures to enjoy in the gallery below.

Z Car Garage Tuned 350z Gets 2nd Place!

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 3:59 pm on September 24, 2013


Congratulations to Patrick Chio for his 2nd place finish in the Modified RWD class in Round 6 of the 2013 Redline Time Attack race! He has been a top contender in this series with 1st/2nd place finishes. Recently he added a Vortech supercharger and this compounded the 350z’s high oil temp issues under hot race conditions. Read Patrick’s report and how Z Car Garage helped tune his 350 to survive the blistering temperatures and demands of the Auto Club Speedway:

Due to a City Tech Auto Body track day at Mazda Raceway Laguna Seca we missed the practice day on Saturday. Arriving on Sunday early morning we completed the check up, tech, registration and temperature was rising to 77 degrees right before our first session.

Auto Club Speedway is known to put a lot of stress on the motor because of the NASCAR banking at high speed. Our Z hit 5th gear, full throttle, 6k+ rpm on the bank over 140mph. During the first time attack session, our Z was able to keep the oil temperature just about 200F through out the whole session at around 82 degree ambient temperature. However, during the 2nd session ambient temperature rose up to 100F+. We saw many M3, STi and highly modified cars forced to pit after the 2nd lap. Despite the high heat, we managed to finish the full session and oil temperature reached 260F right before the checker flag.


We were amazed that a supercharged 350z was able to last the full session in this harsh environment. Rob and his crew at Z Car Garage have done an amazing job again keeping our time attack Z alive! Below is the video in one of the session (Count how many super cars we have passed):

 

Keep up the superb driving Patrick and thank you for letting ZCG work on your Time Attack Z!

For several years we have been helping a group of guys who build these vintage sprint cars to run on the Salt Flats.

Each time Rob has helped dyno-tune these wonderful machines they have broken a speed record in their class!  Check out before/after tuning results:


Just another example of how ZCG loves to help folks in motorsports!




German Old School: Tom’s 2002

Part 2 in a series: ZCG also supports vintage cars of non-JDM origin!

Tuning The Datsun 510’s Rival

Alfas and BMWs have long been rivals of Datsun 510s. ¬†Fighting against both BMW and Alfa for the 1971 Trans Am 2.5 Challenge, a certain red, white and blue liveried BRE 510 coupe took the championship that year and in ’72/’73. ¬†So, at the shop it’s no secret we LOVE 510s and know for a fact that they are much cooler than their Euro counterparts ūüôā ¬† Tom H. is a gearhead and ran a 280zx in the¬†24hrs of LeMons last year with some help from Z Car Garage. Tom recently came to the shop to help tune his beautiful, modified BMW 2002 and we readily accepted the challenge.

 

The 2002 is a 1973 non-Tii “roundie” in Sahara paint with very subtle exterior mods for a clean, pre-’72 Euro look: ¬† shorter chrome bumpers, no lower trim on the doors, deleted side marker¬†lights and ¬†basic BMW steelies.¬† A great stance and handling comes from¬†Ground Control coil-overs up front¬†and Ireland Engineering Stage II springs in the rear with Koni shocks all¬†around. ¬†Tom turned the ’02 into a total sleeper by modifying the motor with a ported head, custom 9:5:1 CR pistons and Megasquirt EFI. ¬†He recently converted to TWM 45mm throttle bodies which complicated tuning so ZCG came to the rescue!

On the dyno, baseline numbers were 98hp/129tq to the wheels. Great plateau of torque available from low rpm but still in need of tuning and full rev range:

After Rob’s tuning the mighty ¬†’02 made 131hp/139tq to the wheels!¬†Here is a short clip of the Bimmer on the dyno:

Just for kicks we even weighed the BMW to see how it compares to a Datsun 510: 2297lbs vs 2160 for Rob’s SR20DET-powered dime.

 

We enjoyed working with Tom and his very pretty(and potent!) 2002. Enjoy the Ride Tom!
