Answer:
All motors and transmissions are interchangeable with each other from the years 90-94, it only boils down to Model and drive setup, such as AWD vs FWD. The only difference I have seen with the 4g63 and 4g63t engines is the oil run off tube and oil feed tube for the turbo, other than that there doesn't seem to be any other differences so to a degree, yes. they are interchangeable
