im just about to fit some perfomance parts and am wondering what sort of power should i expect the spec will be as follows: zero sports induction kit, turbo xs top mounted intercooler, 3" stainless steel exhaust all the way through fully decatted,walbro fuel pump,vf34 turbo, sti pink injectors and remap. The car is a 54 plate 2.0 wrx.

 

depends on who is doing the mapping but realistically you should be looking about 320-340 i would think
