You're gonna need someone to tune the car. Plus you have to extend a few wires off the wiring harness. Then you will need coolant hoses and throttle cable. Then you need to wire the imrc's open with zip ties or buy some deletes.
Pretty easy swap if you have a 5 speed 2v.

96-98 Cobras need imrc deletes or wire them open
