when i went to msd in jan was told in report my t3 turbo is worn ! a mate of my bro has a fiesta rs turbo he is gettin rid off and he reckons it has a t34 on it , i'm goin to see whether he will swap + cash for my turbo but don't know what i'm looking for any clues as to markings (to prove it t34 )etc and what sort of cash adjusment is fair . he has no reciept it came with the car etc , so don't know whether it bull or not about being t34 , don't they look the same as t3 ?
