Just out of curiosity... What amount of involvement would go into putting a 3.2 s motor into a 2.7 5spd car? Besides swapping out the engine and bolting the tranny to it, just replace the DME?
Any 2000-2002 3.2 will easily replace your engine with no other changes needed except if the engine is from a 2002 you need to use your original fuel rails & injecters.
I don't know if there are any differences between base & "S" tiptronics or torque converters, good chance gearing &/or torque converters are so you want to look into that also.
