Alright what you will need:
Axles
Waterpipes
AC lines? (I removed mine so no idea if they reach or fit)
Remove old mounts and make new ones
New Throttle cable bracket
Diagram of how to wire and some patience
Fab up a new exhaust or if you use the heavy stock 3sgte one new brackets and hangers
Fuel pump, you have to drop the tank and change it
While your at it a new fuel filter and lines are a good idea
So you get all that stuff that I vaguely put together you will also need to weld the mounts in place weld up a new throttle bracket. My celica axles fit after widening the rear a little but I'm not sure about the mkII turbo ones people normally use 2 passenger mkI SC mr2 axles. The water lines will have to be made or some junkyard searching on what shape you need. Once you put it in place you have to take some time positioning it carefully before marking the plates doing final cutting/drilling for bolts then going back and checking then tacking them in place before dropping the engine back out and welding them properly then back in again and bolt up the main mounts while you make the torque mounts.
I could go on but bottom line is you can't do this swap with the engine and a set of spanners unless you fork out some good $$$ for someone else to do it and it takes research to know what you need. You can skip the wiring and have that made if you want with a plug and play harness but it's not free. The guys over at twobrutal know what you need I gathered most of my info up off them and eventually when my motor went bang started the swap. I spent all my time thinking out problems while building it nothing just clicked into place I fabbed everything including the overflow bottle hanger
