You may come across a tranny mount that is different, and the wiring is going to suck, since you have to rewire you car for fuel injection.
The rewiring you will need the whole harness, resistors, everything involved in fuel injection from the motor to the ECU to insure you don't have a lot of cutting and splicing through trial and error. If you can find one in a junkyard, just remove and label everything, taking pictures so you can remember where it all goes.
