Gilbert’s Stillen Supercharged G37

Gilbert W wanted a CARB-legal solution for more power on his daily driven G37 sedan.  We’ve had great success with our past Stillen Supercharger builds and this forced-induction kit would be ideal for Gilbert’s needs.

Installation of the Stillen kit is straightforward. We use one-step colder GT-R spark plugs and a 19-row oil cooler:

Better breathing on the exhaust side courtesy of a full Fast Intentions exhaust system:

Gilbert wanted improved handling without unnecessary harshness. The TEIN mono flex coil-over system with active EDFC allows on-board and speed-sensitive dampening adjustments! We installed a similar setup on Tetsuya’s 350z earlier this year. SPC F/R control arms were installed followed by a full alignment:

A relatively new item for Z/G owners is this trick adjustable clutch pedal box from RJM Performance. It offers improved driveability in terms of clutch-pedal engagement and that annoying shudder we’ve all experienced in Nissan’s Z/G manual transmissions:

The PLX Devices multi-gauges are becoming a popular method for monitoring engine vitals. Gilbert is using their Bluetooth “Kiwi” interface allowing display through smart phones. We did a neat install of this unit in Steve’s Vortech G35:

With the supercharger and exhaust in place we dyno tuned Gilbert’s G37. Baseline numbers were 283hp/241tq and it is now making 417hp/319tq to the wheels.  This is a gain of +134hp/78tq which once again shows how consistent power output has been with these kits!

Alex’s Supercharged 370z

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:

JC11314 015JC11314 035
 

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:

Mike’s Nismo 370z

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:

Thomas’ G37 Sedan

Thomas C came in for full 60k mile services and a new exhaust system on his G37 S sedan.

The old exhaust system had an aftermarket y-pipe that didn’t significantly increase power. We installed a full cat-back system from Fast Intentions followed by an UPREV tune. Old vs new:

The new exhaust looks and sounds great:

On the dyno we were impressed with gains from the FI exhaust combined with UPREV tuning. Peak numbers were 302hp/249tq to the wheels, an increase of +15hp/10tq. Check out the mid-range tp redline gains in both hp and tq from 3500rpm:

Dannie’s Infiniti FX35

We worked on Dannie P’s Infiniti FX35 last year adding GTSpec bracing and a custom Bassani exhaust system. Dannie came back to ZCG recently for more mods. We installed additional bracing from Summit/GTspec and Fast Intentions resonated high-flow cats (HFCs) followed by on-road tuning.

ZCG #3 21514 051
 

Here is the front crossmember brace:

HFCs, in place of stock cats (L):

ZCG #3 21514 053ZCG #3 21514 055ZCG #3 21514 062
 

We did on-road tuning to make sure the A/F and timing were safe. Enjoy The Ride Dannie!
