hi all
ive just had a ppp fitted to my 04 sti type uk now running about 305 bhp.in a few months when the warrenty runs out i would like to up the power maybe to 400 ish what would the normal way to go and how much is the cost any advice
big thanks

 

where you based?

 

near barrow in furness

 

you have pm

 

You would need a bigger turbo and new headers to get anywhere near 400bhp

 

I think the headers would be fine, it would the PPP exhaust after the turbo would be restrictive in my opinion. Would need to change to Milltek 3" or equivalent, bigger turbo and bigger injectors.

 

thanks for the info guys
