Depends one what its going into. For a v6 you need to buy a v6 to 4cyl adapter, a dual case adapter, obtain two 4cyl gear driven cases, two cases need to be 23 spline, need a icrossmember, and drivelines.
For a 4cyl you just need a dual case adapter, one more tcase, and drivelines. Crossmember would be a good idea too
