[RPR33]

R33 series 2 (96)

3" turbo back

fmic 600*300*76mm

high flow'd fuel pump

stock turbo (as mentioned before it has steel compressor wheel????)

Profec b boost controller

175rwkw @ 8-9 psi and 200rwkw @ 12-10 psi (boost drop) and running very rich!

I would like to here any thoughts anyone may have on this dyno run.

Cheers.

[munro'sgts-t]

got my car tuned today it made 243hp at the wheels or 181rwkw on 11.2 psi

stock turbo

600x300x76 fmic

3inch dump 3.5inch cat back with stock cat

apexi safc series 1

this is a little on the low side i think concidering every one else with stock turbo is making around 200kw do you think its the stock cat or the safc???

Results as per my signature... currently 226.5RWKW (will scan dyno sheets in tonight)

More goodies being installed currently with ECU to be installed next week:

555 Injectors

External fuel pump

FPR

ECU (Adaptronic)

Custom Plenum

Metal Headgasket

Cam Gear

Cam Shafts

New hoses throughout engine just incase lol...

GT3540 for when Stage 3 highflow is max'd out

And then..... wait for stock internals to crap themselves before installing a RB30 bottem end (Dad won't help me build the bottom end whilst there is a perfectly good one still working in the car )

Now sitting at 262.3 rwkw on 16psi.. We made 279rwkw on 18 psi but it the highflow was being maxed... dropped it back to 16psi to be a bit nicer the the turbo

Added the Adaptronic, injectors, fpr, plenum (although awaiting another ), cam gear + fuel pump!

Tuned to run really rich due to the plenum leaning out no3 with the airflow. New greddy plenum and Garrett to be installed in two weeks.. will update then when the afrs are a little more friendly to my fuel economy!

GTR front mount custom piping

apexi AVCR (would use HKS controller if i was to choose again)

apexi PFC

It made 259.8rwkw at 7000rpm but has very stong midrange but lower tourque and power tapered off in the top. I will try and get a 0.86 hsg and re-dyno and see what the difference is. But as the package stands it is fun to drive and the boost is only set at 1 bar, so with bigger hsg and 1.1 maybe 1.2 bar it should make 270 kw with more tourque.

[Nishant]

This in what i have in my 1991 gtst

Current Mods are:

managed to get 211.3rwkws @ 6284 rpm with 1425mn torque (331mn at the flywheel). Only ran 9.33psi of boost
