Bowfisher under almost all circumstances, you would be a lot better off trading off your 4 cylinder and purchasing a 6 cylinder ride.
You will need EVERYTHING. Radiator, exhaust system, tranny, engine, computer, wiring, and things I cannot think of offhand. Except in certain special cases, I'd say shy away from that particular swap.
