Scott visited Z Car Garage for dyno tuning of his Datsun 510. He had the engine installed by our friend Troy Ermish and wanted Rob to perform the final tune/sorting.

 

When you have a shop perform an engine install it is critical to have it tuned and confirm power/drivability.

 

On the dyno baseline numbers were 129hp/129tq at the wheels. With tuning we picked up 11 hp and 9lb-ft of torque for a total of 140hp/138tq to the wheels:

Scott is coming back to ZCG next month to get a larger exhaust installed as the stock exhaust is definitely limiting output.

Jason S had his 2012 370z supercharged at a performance shop in the Sacramento area. He then tracked us down to install a smaller pulley and raise the boost level followed by UPREV tuning to replace the base CAN tune.

Once we got his car into the shop we realiZed there were several things to handle before increasing the power. First, it is important to put in a colder spark plug in a car with forced induction and we used our proven GT-R units. When going from 280whp to 400whp we wanted to make sure nothing was rubbing so the following items were addressed:

All vacuum and boost lines were secured to keep them from popping off:

   

We corrected wiring at the ART pipes where a wire was touching the exhaust:

  

We corrected orientation of MAF housing:

    

The oil cooler lines were secured to prevent from rubbing anything on the front end:

  

We rectified the flaky wiring to the intercooler pump that allows water to flow into the cooler. No more on/off issues with the pump. With all of the clean-up work sorted we installed the smaller supercharger pulley and UPREV tuned the Z:

  

ZCG has performed many Stillen s/c kits and it’s a wonderful way to pump up your Z with minimal hassle and great power gains. Thank you Jason for letting us sort out your Z!

 

 

Nick K has been coming to Z Car Garage for several years. He makes the trek all the way from Sacramento and we’re proud to be the only shop that gets to work on his 2004 G35 Coupe. In 2012 we first met Nick, UPREV flashed his car and performed routine services.  He had daydreamed of one day doing a supercharger kit.

 

A year later Nick K’s engine was tired. With 209k miles on the clock he dropped the G35 off at ZCG in preparation for a fresh start and…boost!  We removed the ailing VQ35 engine and installed a complete VQ35 from a customer who wrecked his car with 50k miles on it:

 

With the engine out it was prudent to install a JWT HD clutch/aluminum flywheel. We did a Vortech tuner supercharger kit using our recipe of 1000cc injectors, GT MAF, and Aeromotive 340 fuel pump. To keep everything cool in Sactown heat we installed a 25-row oil cooler. In 2013, Nick was on his way with a new engine and boost, enjoying a nice 140hp/105tq bump in power for a total of 386hp/334tq to the wheels:

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:

It is a small world when it comes to the Datsun community and we love being a part of it. Jobie brought his Datsun 510 to Z Car Garage for dyno tuning on referral from our good friend and overall-stellar Datsun dude, Troy Ermish.

 

Jobie’s Dime didn’t always look this pretty, as shown above left running a single carb Z24. James Johnson applied the paint and a year later the car was dropped the car off to Troy for a L20b/Mikuni 44 engine. Ermish Racing prepped the chassis with parts from Techno Toy Tuning on the front suspension, Troy’s Wilwood brake kit and bespoke rear suspension parts.  We are smitten by the stance on this thing, sitting perfect on nicely spec’d 14″ Hayashi Street wheels. Great choices in the interior too:

 

On the dyno we saw peak gains of 8hp/4tq for a total of 166hp/157tq at the wheels. The real improvements can be seen under the curves with consistently more hp/tq throughout the rev range:

 

The car is setup from open track enjoyment yet still street driven:

“I always heard Troy talking about bringing cars over to Z Car Garage for a dyno tune. I try to get the 510 on track ever other month or so. So far, it’s only been to Laguna Seca, but this year, I’m planning on track days at Sears Point as well”

Enjoy The Ride, Jobie!
