How to properly bring a UK-Spec 2004 STi to 300-320HP range?

[Skipper555]

Hey everyone,

Before I ever make any modification to my car I thought I'd check with the experts here what's necessary to increase power to 300-320 HP range without risking much of reliability.

1 - Full Exhaust System (Blitz Nur)
2 - K&N Typhoon Short Ram Enclosed Impreza Induction Kit
3 - Intercooler upgrade needed???
4 - Remap
5 - ?
6 - ?
7 - ?

Any suggestion or comment anyone??

I couldn't find a topic with this question, if someone can, admins are welcome to delete this one.

Cheers!

De cat or sports cat . Decent cat back system and a map will have you pretty much where you want . Panel filter and fuel pump would get you bit more .

Basic stage 1 really

Hello

Just bear in mind that link above for UK fuel not the rubbish we get so cars make less here with same mods still good solid advice.

A good map will be your best thing on list no need to upgrade intercooler????
