i did the change over, any human being with good knowledge to LEARN and take time to do the project it can be done. motor, tranny, ecu with the harness that extends from motor to above gas tank and to the evap canister. you will need drive shafts, shift linkage (if manual) cause that's what my car is. motor mount, i would recommend swapping the guage cluster. if you have the ignition that came with the original motor and key that's great, if you don't, go to dealer they charged me 40 bucks and i had a locksmith program my key for 80, at the dealer to get a key made its best to know your vin number saves alot of time. i just recomment getting a donor car that's wrecked either from autcion or wherever.
