What about using a 4.0l motor
Jeep Mechanic: Todd M, ASE Certified Technician replied 9 months ago

The motors listed are the only motors that will be compatible for your vehicle. If you want to use one of the other motors, you will have to have the transmission and the computers and harness, also.
