i recently threw a rod in my 2002 chrysler 2.7L. i found a 1997 chrysler 2.5L with about 3,000 less miles. are these engines compatible enough to be interchanged, or will this be a wiring nightmare?
Even if the “new” 2.5L engine is mechanically compatible with the motor mounts and the transmission, then you have the issue of the ECM. I seriously doubt if the ECM from a 1997 Chrysler will mate up properly with the TCM and other parts of the 2002 Chrysler, and the 2002 model’s ECM most likely won’t mate up properly with the 1997 engine.
