i've got a 32 gts-t with quite a few km's on it and a big turbo back exhaust and i'm looking for a few extra Nm & kw...

I'm thinking a turbo rebuild and 10psi

a pod with cold air pipe

tuning to sort it out

any ideas of any probs i may encounter with the std computer

any other mods that may be low cost (i've notice 'cooler kits are a bit pricey)

any recommended tuners in the sydney area

is a bleed valve the easy option to increase the boost

1) a high flow panel filter in the stock airbox with a pipe running from the bumper feeding cold air

2) bleed valve to 11-12psi

3) SAFC tuned on a dyno to get the best a/f ratios

assuming your engine and turbo are in OK condition this shoud yield some more power to play with... and should cost less than $500 all up...

Waz.

sounds pretty good. ta for the tip...

what exactly is a SAFC? a brand of piggyback computer? forgive my ignorance

going to rebuild the turbo to be safe as i don't believe it will put up with much more boost. what boost do the ceramic wheels normally put up with?

Hi cul202, I agree with mase, get a RB25DET turbo. swap the wastegate actuator from your RB20DET turbo. RB25DET is 0.4 bar whereas RB20SET is 0.6 bar. The RB25DET turbo flows more air at the same boost level, so gives around 20 rwkw more power. It bolts straightup, so cost is minimised.

Also makes a better base for a ball bearing hi flow later on if you decide you need more.

Hope that helps

That's spot on what i did sydneykid, thanks for the tip off on the wastegate in the other thread. Lots of fun. If you want a car for straight performance then the vg30 would be good but it's a tad lagier. Rb25 turbs is good if u like a bit of drifting and a more smoother power curve.

another option is to get your standard computer re-chipped for like $200.

for about $1000 you could get about 170rwkw.

Panel filter for standard air box. - $100

rb25 turbo - $500

bleed valve - $60

rechip computer - $200

gtr fuel pump - $200

that should be about $1000 and give you a reliable 170rwkw from your RB20.

After that, the next thing should be an intercooler. It's almost summer and the stocky one is a little small for that sort of power.

A GTR intercooler is now worth about $600. piping say another $400..

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
