GTM Performance Engineering: Project Nismo S/C Extreme

[SAM@GTM]

The owner of this fine Nismo we proudly present to you today sent us his showroom stock car with the intent of having a complete transformation performed right out the gate. With all the expertise of our team, we were able to put together a complete package that addresses every aspect of the car while leaving the clean lines of the factory Nismo body work unmarred.

Here is the list of upgrades:

GTM Stage 1.5 Supercharger Kit (550bhp)
GTM 2.5" Test Pipes
HKS Hi-Power Cat-back exhaust
Aquamist HFS-4 Water/Methanol Injection System
GTM 70mm Competition Radiator
GTM Thermostatic Oil Cooler Supplement Kit and Oil Cooler
GTM Vented Fender Liner
OS Giken Twin Disk Clutch Kit
Heavy Duty Concentric Slave Cylinder for OS Giken Clutch
HKS CAMP2
KW Variant 3 Coilovers
Hotchis Sway Bar Kit
SPC Camber Kit
GTM Plug and Play Traction Control System
Work Gnosis Wheels
Michelin Pilot Super Sport Tires


Results

At the heart of this beast, we have our Stage 1.5 Supercharger Kit that combines the responsiveness and mid-range torque of our Stage 1 Supercharger Kit with the massive airflow afforded by our Stage 2’s compressor inlet design. This delivers a torque curve that comes on hard in the midrange and stays flat all the way to redline. With the water/methanol injection system at full tilt and 93 octane gas, we were able to pump out 507whp and 359wtq. Looking at the dyno graph, you can see that 90% of peak torque is available from 3900rpm to its 7500rpm redline.
