Got a Jeep Wrangler YJ from 94' with the 4.0 I6. Also have a 87 YJ with the 4.2 liter I6 in it. Plans are to use the main engine without the accessories from the 258, and use the intake manifold with the fuel injection off the 4.0 to take the place of the carburator. Anyone have any experience with this or just want to throw out some ideas to me? Anything would help!
