hi all just after a bit of advice, i have a v5 sti wagon with 310bhp with printout
all work done by scooby clinic currently have
p1 engine fitted, td05 20g, ecu tek remap uprated fuel pump induction kit and exhaust system, not sure what it is quite quiet really, car pulls very well and i was just wondering what to do next change of turbo and full system inc headers and decats?
thanks

 

Yeah straight through decat with bigger injectors. But if you want to really go all out try an EJ25 bottom end.

 

plenty of tourque with a 2.5 !

 

you got a 20g already mate so injectors de-cat re-map headers and no reason why you'll not be getting close to 400bhp

 

Right, you have a v5 sti engine fitted, its not that good, bin the 20G, fit a vf48, run around 330-340bhp and you should retain your engines (hopefully) reliability.
Fitting a 2.5ltr bottom end will eat your clutch and gearbox (the ty754's are not that good, no matter what people say, 300+lbs of torque and your living dangerously).
You could vastly improve what you have, note your car wont take silly bhp without you throwing 10k+ at it, in which case its not worth it as you can get a well set up new age STI for that money with 400+bhp

That engine wont take anywhere near 400bhp reliably, damn they use to rebuild these back in the day at 320-330bhp and that was a fresh engine with a good (top quality) ecu (mafless).
They have let go at less (seen a virtually standard and running well (no fuelling issues etc)) v3 sti ra throw a rod through the block with just over 300bhp.

**** didnt know that thought they was quite strong them

 

The new age ones are much better and can run 400+bhp all day long the classic ones suck big time

Tony

 

So is a p1 engine any different to sti engine?

 

Its a version 5 sti engine, phase 2, same as the classic MY99/00 STI's.

Tony

 

400hp not a great idea without other mods see Tonys posts. He does seem to have a downer on powerful classics though, probably just jealous

TX.

 

im not looking to go stupid power just tbh its fine the way it is at the moment just wonderd what supporting mods i should do.

 

just to add the car has had uprated internals

 

How old are the bushes, shocks, brakes and ARB's?

With a better handling car you'll get the power down better and in the bendy bit's. I have an RR Printout for 310 BHP with my V5 STi with only a Ninja 2 cat back, uprated fuel pump and panel filter. The engine was rebuilt at 86k and it's now on 110k.

 

tony u and your newages lol. go on tell him to get spec c
