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

 

get the sti ppink injectors (550)

yep

pink sti 550's
vf34/35 0r TD05 16g turbo
full decat inc up-pipe
walbro fuel pump (recomended)
STi tmic with scoop and under tray
then a remap to set it all up

 

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.

 

.........and then your clutch will slip and the bug 5 speed box will break LOL
