I know ill get some "why in the world would you" but the way i look at is why wouldnt i want one of the best drivetrains ever produced in my car. Anyway im not even sure were i would start so. I have a 97 ws6 with a t56. Will the TTA motor fit in a 4th gen engine bay? Im pretty sure the buick motor wont because of the heads. im also thinking Ill need to find a BOP T5 bellhousing/flywheel/clutch from a non-turbo car, then adapt the T56 to the 4-bolt bell with a tremec adapter plate.
