There is quite a bit that you will haver to do to put a S/C on your OHV. I am in the process of doing just that right now. The S/C is the last thing that you want to put on there. Your are going to need all the bells and whistles. Intake, MAS, TB, Injectors, Headers, Fuel Pump. The kit that you are looking for is the Vortech for 91-94 4.0 OHV. A few mods to the Battery need to be made to get it to fit on the newer models. How much have you done thus far?
