Type of Turbo

Lads need to know what 'letter' would be on my 01 bugeye WRX. suppisedly theirs a letter on the turbo (X,Y,?) which differentiates between an impreza, forester and sti turbo's. Anybody have one lying around? or could someone tell me where to find this info.... without taking of the tmic, heatsheild etc

Cheers

Do you mean what turbo it is ? Its a TD04 on your car but maybe you mean something else ?

yeah know that renno thanks, but there's also supposedly a letter on the turbo to differentiate it from the forrester, and the STI Turbo's, i could be informed incorrectly . basically, i need an actuator to suit WRX bug
