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:

Matt M is another member of the Inconceivable Racing group and visited ZCG to supercharge his 370z Convertible. Here are a few pictures of the Stillen kit installation:

 

Matt came back to have us install some ART pipes and a Fast Intentions catback exhaust system:

 

ART pipes in place:

 

OEM vs FI exhaust system:

 
 

Being base model Z, Matt wanted to put slightly wider wheels on and sticky RE-71R tires for track days:

 

We love the PLX Devices gauge that neatly replaces the clock with a multi-function display to monitor vitals:

 
 

Finally, also installed new end links for his sway bars:

 

On the dyno we retuned with ECUTEK to maximize gains from the bolt-ons. Final numbers are 402hp/354tq to the wheels, peak gains of 32hp/24tq. After 4000rpm gains of almost +50hp/tq are seen:

Enjoy The Boost, Matt!




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!

 




Sitting Pretty: Rich’s G37 Sport Coupe

Filed under: 370z,Featured Cars and Projects,Performance
by Alvin G @ 7:07 pm on June 27, 2017

 

We met Rich G when he called us about the suspension on his 2011 G37 Sport Coupe.  After visiting a wheel shop to get new wheels/tires installed he reported the car was bottoming out and felt very unstable. Rich sought out a specialist (sound familiar?), called ZCG and met with Rob to assess the car. We put the G up on the rack and noticed installation of very aggressive H&R lowering springs. The springs and aggressive wheel/tire fitment made the car bottom out and also cause excessive camber wear.

 

We immediately changed the springs to a set of Eibach progressive rate units which are fantastic for a car that just wants to be slightly lower and enjoyed as a daily driver.

 
 

The wheels were wrapped in new Hankook v12 evo S2 tires and SPC  F/R control arms help keep the suspension properly aligned. The G still has a nice stance:

 

Rich’s son is a younger fellow and removed the rear muffler so we put it back on for Rich. If you are going to wear tires like an adult sports car…it might as well sound like one too:) After the G was sorted we heard from Rich a few weeks later and he was super stoked with the way the car rides.  He was also happy to report perfect tire wear too.

 
 

So here we have another great example of the specialty shop working for you! Enjoy The Ride, Rich!






Hello Zcarblog readers! In our next blog posts we aim to demonstrate the importance of a specialty shop for your Nissan/Infiniti/Datsun.

Let’s begin with Justin L’s 2013 370z. He had a Stillen supercharger installed at a local shop and while there are many competent shops that can get your car ready to go, the specialist exists for a reason: we have become proficient at specific installations because the are part of our daily routine.

 

The Stillen supercharger kit for the Z34 is an install we are intimately familiar with, and as a result we corrected several things on Justin’s car including engine codes and a fuse in the intercooler pump system that wasn’t allowing water to be pumped into the IC.  We also adjusted the clutch pedal and crossed the T’s and dotted the I’s as we do for many folks that bring their cars to ZCG.

Rob tuned the car using Ecutek software flashing with a MAP sensor instead of the MAF and Stillen-supplied CAN tunes.  Moving to speed density allows more control improved driveablity from idle to on boost. The results were impressive:

 

Justin’s Z came to us with 360hp/291tq and left with 396hp/321tq at the wheels. Gains of 36hp/30tq using slightly less boost as well with gains throughout the entire rev range. Justin is a happy camper and hopefully we’ve gained another customer for life. Long Live The Z!
