Alex T is the owner of this pretty Black Cherry Z34 and he visited Z Car Garage on referral from our boost junkie friend and customer Juan F.  To satisfy Alex’s desire for forced induction we installed a Stillen supercharger kit that was actually used on Grant K’s Nismo 370z.

 

Out of the box, this older Stillen kit left plenty of room for improvement so we invested in several upgrades like 1000cc injectors, Aeromotive high-flow fuel pump, pulley and these engine oil/automatic transmission coolers:

 

The transmission received a GTM valve-body upgrade and stock bypass valve was replaced with a blow-off valve:

 

Fast Intentions test pipes replace factory cats:

 

To put the power down more effectively we installed a Quaife limited-slip differential, using the stock 3.36 R&P:

 

With all of the modifications and UPREV tuning Rob extracted 435hp/343tq to the wheels. This is a 147hp/104tq gain over stock:

 

To monitor vitals Alex chose PLX Device’s OBD2 multi-gauge. We first installed this trick, wireless sensor/gauge package on Steve’s G35 with an iPhone interface.  For Alex’s Z34 the multi-gauge was seamlessly integrated into the OEM pod:

We love the brilliant display and wealth of data that can be accessed:

 

Enjoy the Ride Alex!

Stillen supercharger month continues at Z Car Garage! Our last reports included Daly’s G37 sedan,
David G’s G37 S coupe and today we bring you 2009 David S’ G37 Convertible. The trifecta of supercharged Infiniti G-cars is complete!

 

As with previous builds, the Stillen supercharger kit installation is straightforward. A Stillen oil cooler and colder plugs were added:

 

From NA to boost!

 

Out of the box with the Stillen-supplied CAN tune the ‘vert made 408hp/325tq to the wheels. This is a great improvement of 122hp/75tq over stock but at Z Car Garage we can do better!

 

Rob’s tuning yielded +12hp peak with smoother delivery all the way to 7500rpm:

 

With 420whp we also thought it would be prudent to start David off with some fresh tires 🙂
This concludes our Stillen supercharger month at the shop…can we help you boost your Nissan/Infiniti?

 

Mike U visted Z Car Garage back in May for Stillen intakes on his Nismo 370z. The Z was a gift to himself and with just 2800 miles on the odometer he got the modification bug. In addition to the intakes we installed a Fast Intentions exhaust system and Eibach springs:

 

Exhaust before/after:

 

A few more shots of the system:

 

The Fast Intentions system looks great and also frees up some power!

 

We saw a 7hp peak gain at the wheels over baseline:

 

With Rob’s UPREV tuning Mike’s Z34 now makes 315hp/256tq:

 

Eibach springs improve the stance and SPC camber arms keeping the alignment in check:

  

We dig the slight ride height reduction:

 

Enjoy The Ride, Mike!

We have an exciting update from our Datsun Roadster friend Francis A. Last year we helped Francis sell his beautifully restored 1968 Datsun 2000 by listing it in our FOR SALE page.

 

The roadster is now across the globe with its new owner just completing a 5,000 mile tour through ten countries: Germany, Austria, Slovenia, Italy, Croatia, Bosnia-Heregovina, Montenegro, Albania, Macedonia and Greece…

 

Thank you Francis for sharing these photos with us.  Though it might be painful to see somebody else with your baby it is obviously in good hands!

 

Stillen supercharger month continues at Z Car Garage! Last week we featured Daly’s G37 sedan and today we bring you David G’s 2009 G37 coupe. With 57k miles on the clock David wanted to go forced-induction on his G37 with Stillen’s CARB-legal kit.  As with all builds, each customer gets a dedicated rack for parts:

 

We also installed a  JWT HD clutch/flywheel, Z-Speed T/O bearing and 19-row oil cooler:

 

For added peace of mind we also performed full 60k services. Here are a few in-progress pictures:

 

On the dyno, the Stillen-provided CAN tune put down 406hp/309tq to the wheels. Rob’s tuning further improved hp and tq throughout the entire rev range for total of 433hp/325tq!

 

With an improvement of +137hp/69tq over stock David is trying to keep his smile under control. Enjoy the Boost!
