HI, i have a 51 reg wrx bugeye which is currently producing 280 bhp, in the next two weeks it will be boosted to 340 bhp. i already have a air filter, full decat and a walboro 255 fuel pump. i was wondering whether anyone could tell me what injectors i am running as they are standard and whether i would need to change them for them to cope with the power.

thanks in advance.http://images.ibsrv.net/ibsrv/res/sr...lies/thumb.gif

i believe they are 420 standard size mate as for uprating them alot of people go for the sti injectors as they are 550

You have 440 injectors. You would probably need a fuel pressue regulator to get 340bhp from them.
Also dont forget you'll need a bigger turbo too e.g TD05 16g, VF34/35

std injectors are 420cc

you need 550 injectors from the STi but you will also need a bigger turbo to make that power and a very good remap.
