you will also need a new ecu. What model do you have (cx, dx vx, lx, ex ect.) Unless you have an ex, si or vx, you will have to wire for vtec (also if you have an ex, or si, dont swap with that engine, you'll see a 2 hp boost.) Your also going to have to make some wiring changes sence your going from an obd1 car to a obd2 engine.
