Swapping Issue!!

New to this supra thing. question is my 89 supra(turbo) has a 7m-ge engine, which was swapped from its original 7m-gte, what fundamentals will i need to have/know to re-swap it back to the original engine?

Why would you do such a thing?

No, the thing is i bought the car with the 7m-ge engine in it already. i just want to go back to the 7m-gte.

Ah, I see now. You will need a motor complete with ECU and wire harness. You will have to swap out the harness with the motor. If it is a manual trans car you will need to run the R-154.

To do this swap on your own you will need a shop with a decent tool collection. You will need be able to find your way around the wires, as well as the mechanical parts. Engine swapping is not the easiest task.

Ok. i guess its time to get busy. thanx.
