Have any of you guys ever put a supercharged motor in a non supercharged x terra ? If so , Is the tranny the same? Is it just a matter of motor and harness? Is the radiator different?

 

What model do you have?

 

I would assume that the tranny is either the same, or at least interchangeable...
You're best bet would be to make friends with the parts guy at the dealership and see what parts are different according to his database. you might even be able to determine how the parts are different if his printouts are any good.

 

mine is an SE. Are the SC's 3.3 or 3.5?

 

for the extra 30 horsepower it isnt really worth the trouble imo but you will also need the ecu. Im pretty sure the trans is the same
