I have some questions that may sound stupid, i am asking the pro's for some direction. Heres my dilemma, couple of months ago i bought a 1989 wrangler from a police impound auction (not bad shape, new tires, no top came with clear title) i got it started and has a heavy knock in the motor. In my search for a motor on craigslist i ran into a guy selling a 1997 wrangler for parts or salvage (no title) the 97 runs great as is very clean also. They are both 6 cly. but the 97 is injected and 89 has carb. I would like to make one street legal. Is the swap possible? Or am i stuck with a jeep just to go mudding in?any and all comments, directions, and ideas would be greatly appreciated. By the way the 1997 was part of a bankruptcy in which the financial leinholder didnt think it was worth picking up.
