post is a bit clustered...but here goes.

your donor car will have everything you need for the swap. you will have to swap engine bay wiring, ECU, axles (along with tranny of course) and possibly the throttle cable. the swap is fairly straight forward..oh, i cant remember if the radiator is different or not.

whats gonna be a bitch is getting the sr out of the bent up chassis. oh, and make sure the oil pan isnt dented when you put the sr in your chassis.
