the upgraded 60 trim ct26 is fairly popular and lasts for a fair bit from what i can tell.. i can't say personally as i don't have that particular turbo

i currently run a 46 trim which has good spool up and is throwin 278rwhp on only 9psi... so she's a damn fine turbo... i'm pretty happy with it

also why do you want a 2mm hg? have you had alot of machine work done which has caused your motor to go out of spec or do you want to lower your compression?
