Wrx to over 300bhp
Hi guys,
So cars off the road at the moment due to a small crash and I'm thinking about keeping it off and doing a tune up to break the 300bhp mark. Right now it's sitting 270-280 with the PPP map and decatted up and down pipes, cobra back box. It also has a stage 2 competition clutch which is ideal for this. Any way from what iv been reading it's got to be essentially turned into an sti before mapping, td05 turbo, sti intercooler, injectors. Would I be correct in assuming this? Or has anyone else done it any other ways?
Cheers guys

Save yourself the trouble and expense and just get an Sti, a far better modifying platform in every way with brakes to match performance.

I did think about this but.. for a decent STI I'd be looking at least 7000 which in my head after totaling up parts n tuning it would be cheaper doing it through my wrx? The differences I can see with and sti and wrx are... brakes, intercooler, gear box, injectors, turbo, suspension and my wrx is really most the way there. Do you know about any other differences ?

What make you think it's 280bhp? You had it on a dyno?
Is it a UK wrx?
I wouldn't have thought by just sticking a PPP map on there that you would get a 30% increase in bhp?
PPP don't use a full decat dp either so probably won't be running to it potential anyway.

You make a good point I'm just going by what I was told when I bought it by the guy who got it mapped (but no print out) but that's beside the point no? Because it would be a new map I'd be putting on it anyway.

For a start your WRX doesn't have the Sti's 6 speed gearbox, its suspension or brakes so it's far from most of the way there, and there are a lot of other differences too. If you're satisfied that you will never look for much more than 300 bhp then your WRX is probably ok. If at some stage you want to push to 350 and beyond (as many people soon do) then the limitations of the WRX platform become all too apparent.

Hey Come on now guys, I had yet to ever have any sort of incident before that one. We all do silly things in our cars from time to time, you live and learn the hard way. Anyway as far as WRX 300 goes, The brakes on the front of a WRX are 4 pot ones same as the sti correct? So just need the back? Suspension... An after market set would do the same job as Sti And Paben if I was wanting to go over that mark I would be uping the car as well like you said but for finance wise if your doing the work your self its a lot cheaper to buy the wrx and tune it too 300 than it is to buy and sti same age and miles and tune it too 300. For the same car but STI id be looking about the 9K mark, and to do that work my self all of it I recon I could do it for just under 3 haha.
But yeh time will tell still doing repairs just now. Still looking for a control arm and steady bars
cheers guys!

Unfortunately the weedy front brakes on a WRX are very far away from the Brembos on an Sti!

WRX brakes are marginal at best. Need Brembos from an STi or aftermarket (APs etc).
330bhp is about the limit on a WRX before it no longer makes financial sense. For any appreciable gains on a WRX you need an uprated fuel pump, bigger injectors, sports-cat, bigger turbo (TD04 Hybrid, TD05 or VF), air filter, 3-port boost solenoid and a remap at the absolute minimum. That should see you 300bhp or higher depending upon turbo. Ported headers, up-pipe, wrapped exhaust, STi TMIC all help but aren't essential (worth doing all at the same time though). Most of the parts can be picked up cheaply off an STi.
It won't be an STi of course because you won't have the AVCS, 6-speed, trick-suspension, steering rack etc but you'll have very decent performance for maybe 1/2 of the price of a stock STi. If you want more power than an STi turbo can give (330ish) then you may as well buy an STi, as you'll need the 6-speed box sooner or later and it'll work out cheaper in the long run.

I've read all kinds of different things on scoobynet about what brake discs/pads fit retain cars and what needs changing to fit certain things. It's a simple question!!

Thanks for a sensible answer mate. I've got 18's on mine and have read that minor adjustments need to be made in some instances. I wanna change my discs and pads because the standard ones are pretty ****e

Tyres aren't a problem for me as I've got Goodyear f1's all round but I just hate the standard discs and pads. Get a lot of squeal and they don't perform aswell as I want them to.
I take it it would be a straight swap for the gold brembo's then ? If this guy hasn't got them for sale anymore can you Recommend anywhere else I can buy a set of gold brembos from ?
