I have a 94 cherokee with a **** 4cyl in it. I got this jeep for free and i want to swap out the motor and lift it. Need to kno what motor is the best way to go suspension ect. All help will be greatly appreciated.

 

I suggest a 4.0 I6...

x2 on the 4.0

 

What kind of work is required to drop the 4.0 into the jeep? Is it a direct bolt in with same ecu and all or do i need new harness etc

 

4.0L but you will have your work cut out for you. You need to massage the firewall and get the wiring harness from the donor including the ECU. The transmission is also going to need to change along with the motor and ECU.
To be brutally honest you would be better off trying to find a 4.0L Cherokee to replace your current 4 banger Cherokee.

 

If i find a 4.0 cherokee what work is needed in that motor swap to my jeep? Also what tranny and rear should i go with and were can i find them?

 

i think what he was saying is sell yours and buy a 4.0 one.

 

You can do the swap and spend the money sweat and blood to get the same thing the regular 4.0L owner already has so in the long run it is your choice. If it were me I would look for a different Jeep to start with, if you need more power than the 4 banger.
That was the root of my prior post.

 

i agree sell 4 banger and get a 6cyl. But if you must do a swap get the 4.6 stroker!!
