If i were u i'll call Limit Engineering but u have to remember that if u go for a bigger turbo you also have to upgrade the injectors, chip,converter, tuning, etc... Limit just did an upgrade on my TE-44 to 67 complete for $625.00 plus shipping. This is the first time i dealt with them and Chopper (turbo guru) just don't do what you asked for he does ask a lot of questions regarding your current set up so you won't have no surprises.
