4.0L H.O. swap from '91 XJ to 87 MJ

Recommended Posts



I decided this morning that I have to make some more space, so the ' 91 XJ is going to go to somewhere;

the motor is going to replace the struggling I-4 in my  '87 Comanche.


I am wondering what work I have to do to get that done.

I am wondering what all I have to transfer, and I might appreciate some specifics that would help.


I figure I will transfer the engine and accessories from the (XJ), and that would include the:


wiring harness,




what else ?


Thanks very much.
