Recommended Posts

Brand new head from Nissan, Jun 272 in and ex cams, 10.8mm(?) lift, special retainers and all the jazz needed to support the cams and high revs, heads extensively ported.

Big dollar hypertune plenum and single throttle body setup

Updated tune. Degreed cams. 3 degree intake and 10 degree exhaust correction expanded torque curve like a balloon. Torque comes on 200-300 rpm earlier, bumps peak from 330 ft.lb (445 Nm) up to 425 ft.lbs (575 Nm), and drops off less at 7500 rpm.

Power at the wheels on a DynaPack 4 wheel dyno bumps from 390 WHP (290 kW) to 527 AWHP (393 kW) at 17.5 psi on my boost gauge and 16.5 psi (corrected for atm conditions) on the dyno.

Mods:

Blitz Nur Spec front pipe

De-cat

Hi all,

Couple of people have PM'd me asking me to put up the dyno sheet.

R33 GT-R.

HKS GT-SS

Apexi Power FC

HKS 3" front pipe

3" Gutted cat

3.5" HKS cat-back exhaust

HKS pod filters

post-13169-1282195535_thumb.jpg

I reckon I could go further, just need fuel pump, injectors, Nismo AFM and boost controller.

Hope these are much of a help in your turbo selection.

1995 R33 GTR - 81,000kms

Unopened motor.

Garrett GT2860R-7 Turbos

Adjustable Actuators

16psi - a VERY safe tune to preserve engine life.

Apexi super suction kit.

Blitz FMIC

Full 3" titanium exhaust

New spark plugs

Oil cooler + catch can

Power FC + Hand Controller

Adjustable Cam Gears

284.8rwkw - which is somewhere around the 260awkw mark.

Makes full boost around 4000 rpm, and sounds incredible. No turbo kick, just smooth increase in power all the way, great for all types of driving.

Would highly recommend this setup to anyone with a budget.

Thanks to the guys at Racepace, Bayswater VIC
