UPREV Tuning For Your Nissan/Infiniti

Filed under: 370z,Featured Cars and Projects,Performance
by Alvin G @ 12:38 am on July 14, 2017

 

Today we bring you three cars that received UPREV tuning to maximize performance gains from common bolt-on parts like intakes and exhaust systems. Enjoy!

Sean’s 370z

Sean visited us for an ART pipe install and to correct a few issues with previous intake/exhaust installation from another shop.

 

Rob UPREV tuned the Z with great results gaining 25hp/12tq for a total of 337hp/274tq to the wheels:

 


Sean also wanted to use a new feature from UPREV called the ARC(Advanced Racing Controls) license. This add-on service to the existing UPREV Flash allows you to have adjustable launch control, burnout mode, and flat-foot shifting for $150.  This is for cars with manual transmission, VDC/cruise control. Call Rob for more details!

Nick’s 370z

 

In 2014 we UPREV tuned Nick’s 2006 black 350z…and now he has a 2010 370z so it was time for an UPREV reunion!  Nick had Stillen Gen 3 Intakes and the Fast Intention CBE w/ 18″ resonators so it was prudent to get a proper tune and extract their full potential.  With tuning we saw peak gains of 7hp/8tq for a total of 318hp/262tq to the wheels. Note the great mid-range gains:

 

 

Karl’s 350z

Nick came in to ZCG to tune his 2005 350z with bolt-ons, and we happy obliged.

 

With UPREV tuning Rob extracted 6hp/11tq for a total of 268hp/251tq. The peak numbers may not seem impressive but look at the area under the curve after tuning. There are significant gains in hp/tq throughout the rev range:

The OS Giken DIFFerence: Eric’s 350z

Eric T hails from Benicia, CA and he is one of the key members of Inconceivable Racing along with our customers Matt M and Rasheed B. This is a group of enthusiasts that got into Z cars and are now obsessed with taking them to open track days and events like Shift Sector. What is really cool is that both Eric and his wife run their HR-powered 350z cars together at the track!

 

Here are the couple enjoy their Z cars at Laguna Seca. It is a small Z-car world and we have worked on Eric’s wife’s 350z Convertible because it was our man William’s!

 

Eric had been to several independent shops and wasn’t really happy.  Rasheed told him about ZCG and we met with Eric to help sort his Z.  After driving at Laguna Seca, he was frustrated with corner entry and exit speeds. This was a result of not putting power down effectively through the open differential on his Base-model Z. Our solution was to install the OS Giken limited-slip unit:

 

Here is the unit being installed with a 4.08 gear, all new bearings and seals.  We also added a NISMO Diff cover:

 

 
  
 

The diff all buttoned-up and installed on the car:

  
 

With the car up on the lift we noticed one of the bushings in rear subframe was leaking. The subframe was pulled and all bushings were replaced with with SPL solid bushings. The diff received Whiteline bushings:

    
 

The aftermarket exhaust system was rubbing on the rear chassis brace and had a rubber pad wedged in between as the solution from a previous shop. We fixed it:

 

The exhaust was also rubbing on the rear sway bar, where a heater hose complete with hose clamps was used as an isolator. We fixed this well:

 

Motordyne ART pipes were installed and the Z was retuned with UPREV:

 

On the dyno we found peak gains of 7hp/11tq for a final 303hp/265tq to the wheels. More importantly the gains can be seen throughout the rev range:

 

 

 

After we performed this work Eric attended a 2-day race event at ‘Seca for his birthday. He was super pumped with the Z and it performed well. He’s a ZCG believer. Enjoy the Ride, Eric!

 




Arvy’s 350z

Arvy B had PPE long tube headers installed at another shop. From the pictures below you will see that these headers were installed with missing nuts and bolts and the pipes were touching the driver’s side underbody. It was unbearable to drive:

 
 
 

In the engine bay a factory fuel hose that went above passenger side had been replaced with a fuel vapor hose. This is dangerous as only a factory, high pressure fuel hose should be used:

Scott’s 300zx Convertible

Filed under: Featured Cars and Projects,Maintenance,Performance
by Alvin G @ 3:04 pm on January 27, 2017

 

Scott N visited ZCG because he felt the suspension on his 1994 Z32 ‘Vert could be improved.  The Z33 Rays wheels look sharp on this 300! We installed TEIN coil-overs and a few other goodies:


Here are the existing shocks and the new TEIN street coil-overs going in front and rear:


Z1 upper control arms:

 

SPL tension rods so we could fully adjust camber up front:

 

The rack bushings are vey common problem on z32s so we replaced them. In the back: the aftermarket adjustable upper control arms were making noise so we replaced them with OEM parts and performed a full alignment.

Scott is super happy and Enjoying The Ride!

 

 




Mike’s Vortech Supercharged 350z

Filed under: Featured Cars and Projects,Maintenance,Performance
by Alvin G @ 2:05 am on January 11, 2017

 

Mike W has been a Z Car Garage customer for many years and he decided it was time to go forced induction on his 350z with a Vortech supercharger kit. It is very important at ZCG to offer packages that are proven and a customer can count on us to do the homework for them. All they need to to is enjoy the ride…

 

We installed a V3 supercharger kit with JWT S1 cams, Bosch EV14 1000cc injectors, Aeromotive 340 fuel pump, DC Sports headers, ART pipes, and Stillen oil cooler:

 

 

We also added a few ZCG refinements including our cold air intake kit,  silencer bypass (quiets the race gate from Vortech), and a ZCG heat shield to protect fuel lines from header heat.

 

On the dyno we UPREV tuned using a GT MAF and saw gains of 169hp/98tq for a total of 419hp/341tq to the wheels:

 

Even though Mike’s Z is a 2003 it only has 30,000 miles!  While the car was at the shop we performed 30k services including replacement of all fluids, drive belts and going over the entire suspension and brakes. We also performed a fender roll:

  
 

DEFI gauges were installed in the dash:

 
 

Mike wanted us to take care of a few things that were bothering him like a failed passenger side window motor. This is common in Z/G35s and we have fixed it many times. Thanks for letting us work on your Daytona Blue Z33 Mike. Volk SF Challenges are sweet.  Enjoy The Boost!
