I know this has probably been done to death but just want som advice of people running 330-350 bhp on a blobeye wrx, it will be getting the odd blast but no track use.
Iv spent the last few month sorting out the body work of the car so I'm ready to tune it up abit.
Currantly running 260bhp with a cat back exhaust, panel filter and map.
Cars on 105,000 fsh and runs great.

Iv done some searches and think I'm going to need, correct me or other suggestions are welcome.
Pink injectors
Td05 or vf34 turbo
STi tmic and y pipe
Walbro 255 fuel pump
Exhaust Up and the down pipe (do i need to remove both cats, just thinking of mots and noise)
And finally map

 

I wouldnt be pushing 350bhp in a WRX, the gearbox being the weak link. Go for around 310-320 bhp and make it last. Vf35 turbo is a good turbo and can be had for around £300. Dont forget brakes/tyres/suspension aswell.........often overlooked in the quest for more power. May be worth getting your engine compression tested so you know you have a good engine to start with.

 

Yes the car has sti brakes and tein coilovers, a compression test is a good point, yeah I'm just thinking 300+ ill be going to a well known mapper when the time comes so they can advise on saftey.

 

Also is a full decat needed?

 

No, you can have much more than 350hp with the STI ppp downpipe (with sports cat).

I'd expect all the WRX cats to have to go (i.e. up-pipe, down pipe and centre section cat), all to be replaced by the single STI PPP cat (plus 2x decat pipes, obviously).

The single PPP downpipe cat is still MOT friendly as well.
