Guys, Has anyone converted a 2.5 to a 4.0? I have a 99 TJ 2.5 and found have a 02 4.0 engine to rebuild. Some questions I have are "Will the wiring harness and ecm... work for the 4.0 motor? I understand the manual transmission won't - but plan on replacing that as well. Also - I am interested in stroking this motor or any other suggested upgrades that might boost the torque and/or HP. Any advice with changing this over would be great. Thanks in advance.
