okay I know the AMC 2.5l hasn't changed much since 1991 when MPI replaced fuel injection. But could you swap a '01 4cyl into a 93YJ? If not how new can you get? Was there some change in '97? and try to keep the 4cyl bashing to a minimum, it might suck, but this is the quickest way to get me back on the road. A drivetrain swap is in the future.:flipoff2:

i have a friend who swapped and 95 4 banger into a 91 and had no probs thats all i can tell yah, dont know much about them
