Can anyone please help with mods i want to do to get the best out of my 1996 Jap import WRX, ive already got a full decat exhaust system, induction air intake, 255 ltr fuel pump.
Which way do i go, bigger turbo, bigger injectors, does a stainless inlet manifold make a differance? any advice would be much appreciated. iv'e got about £600 to spend.

Not sure what you have on that year.

I'm thinking

TD05 - upto 350hp with ALL the right supporting mods
380 or 440cc Injectors (440's would be at their limit at 350)
A decent intercooler, either top or front mount.
New ECU or ScoobyChip.

There are other odds and sods, but £600 probably wont cut it.

PolarPerformance have a few options regarding 'chipping' but as welloil said you'll need a bit more than £600.
What you could do though is spend it on some suspension goodies to take full advantage of the power you have at the mo.

An ECU remap to 1.1bar should see you up around the 280BHP mark using an off-shelf map.
Using a bespoke map (i.e mapped for the car), this could push on to 290-300BHP.

If you can pick up a set of 2nd hand 440cc injectors and a 97> map sensor then this can be pushed on to around 1.3bar and 320BHP/330BHP. But this would probably take your budget upto around £700-£750.

Editted to say : 440's are at their limit at 1.35bar/11.0AFR, unless a pressure reg is used to up the pressure. Oh! and I wouldn't advise running 1.35bar on the standard slanty intercooler, so you would need to factor that in.

cheers lads, got a chance at some 740cc injectors for about £160, would this be a good idea? then i can look at maybe the ECU

Scott.T@PolarPerformance

If there 740cc Venoms from the states then don't bother. they are resized 380's and they have issues.

740's are also overkill unless you are going for mega power.

550's will probably give you all you ever need.

your so right about what they are, thanks for saving me the money, i am also just looking at some Nismo 555cc, would they be ok? (dont know much about these type of mods)

if you look at post 4 Scott T has given you some info.
most of the people i know who have upped the injector size normally go for 550cc but it all depends what you want out of the car
