Well it's done. It would seem that swapping a four to a six that was available in the YJ would be relatively easy. NOT!!!. Its in and running great with twice the HP. The little red YJ is peppy now. The craziest thing was the wiring. I purchased a same year six cylinder harness and computer but it would not work with the rest of the wiring in my Jeep. I ended up using the four cylinder harness and adding two wires from the computer to the #5 and #6 injectors. You can even use the four cylinder distributor in the six, just change the cap and rotor.
