Hello all, i recently purchased a 96/97 uk spec impreza turbo, its completely standard except from a rear box ive just put on. Now how do i get the bhp up to import spec and what air filter and dump valve do you all recommend? i ideally think i wanna keep the recirc type i have but want one with a bit more noise. Any help would be great

Cheers all

 

If you want more noise, get a quality cold air induction kit. Quality = not ebay! Or my personal fav, stealth air box mod. Remove the silencer inside the front wing and install a velocity stack.

Pics start at post#3 I know this is for newage, but I have performed this mod on 4 classics.

For more power, go with a complete turbo back exhaust and up-pipe. Then book it in for a remap.
