You will need:
Twin-plug distributor (JB Racing is the best, hands-down) Additional CD box Additional coil Machine heads and lower valve covers for the second plugs Plug wire harness At 10.5:1, you NEED it to run on pump gas.

Twin plug spark
An alternative would be to use a direct fire system such as the Electromotive XDi or XDi2. With one of these systems, you eliminate the distributor (no expensive caps to buy), coils, CDI boxes, etc. You will have to mount the two DFUs (direct fire units) and find a place in the cabin for the control box. The wiring is not difficult to complete and as a bonus, you will have infinitely adjustable timing controls. The cost should be similar to buying the new distributor and associated hardware.
