Hi,

I am looking at buying an Impreza Sti on a 03-05 plate in the next couple of months and would like to increase the power to about 350BHP, but what I am not sure on is how would I achieve this and would I have to do any major upgrades to the engine, Gearbox or Clutch? I was hoping that I could achieve this by just re-mapping the ECU!
Assume that the car is completely standard as well.

Cheers

Welcome to scoobynet


for 03-05 cars the gearbox and clutch should be fine at that power level as long as you dont do drag starts from every set of lights, but you will need to upgrade the exhaust system, bigger fuel pump and a remap should see you about 320, to get anymore than this i think a bigger turbo from one of the later cars is needed, along with bigger fuel injectors, standard airbox and intercooler is usually good for around 400bhp so no need to upgrade them.

if you were to go for an 05-07 car only the basic mods and a remap will take you to somewhere in the region of 360bhp and 380ftlbs torque, with it being a 2.5 and having the vf43 turbo as standard.

I was thinking of getting the 2.5 version but I have about 10K to spend on a car including mods! and really wanted an sti with less than 40K on the clock! Not to sure with one's with higher millage!

You will need a bit more than 10k for a hawkeye with under 40k on the clock

unfortunately rbaz is right, i picked my hawk up for 14.5k with 8k on the clock, i think you would be better looking at an earlier 2 litre model

TheDom

I think you guys might be right! I have found one on Autotrader for just over 10K,
2006 SUBARU IMPREZA 2.5 WRX STi Type UK 4dr Saloon

plus if I buy from a dealer I would be trading in my current car in as well! (only worth about 2K tho)
The other option is buying a standard WRX and moding it to about 350 that way, but I am not sure if they use the same components as the sti!?!

That's cheap, worth a good look at!

i'd deffo take a look at that one, dont bother with the wrx it will only cost you more in the end and you'll wish you had just bought an sti.

Bargain if its a straight car
HPI it all the ones I have found cheap have turned out to be cat C or D

Newage 2.0 STi (01-05) - Decat exhaust system and remap (with reputable mapper) along with uprated fuel pump should see 340-350 bhp and torque not far behind. VF35 turbo maxes out at about 350 bhp. Maybe £1000-£1200 to do, but quite likely to be able to pick one up ready made. Std clutch and gearbox fine for this. Do not go WRX route IMHO.

Blimey! Really good price for such low mileage. Can I ask did you buy it off a dealer or privately? Sorry am being nosey.

No worries fella

bought it from a dealer, took me a while to find it, it only had one previous owner a fella called graham hill , wether it was the graham hill or not i dont know lol, he'd only used it as a weekend car but swapped it in for an aston martin

most of the info is in this thread:

Sorry for the thread hijack but Rich what a stonker of a deal. Nice one! Took me 6 months to find mine. Really hard to find a Hawkeye STi in black I must say. Was beaten a few times to the post till I got mine.

remember if you can get a sti ppp you will have the pump uprated and a prodrive exhaust ... replace exhaust up to cat leave prodrive cat in place for straight mot pass get it mapped and it will see 330 340 easy and 2 litre is forged ish and cheaper on road tax ... 2l sti ppp imho
