Swapping a 6 in place of a 4

How much is involved in swapping in a 6 cyl 4.0L in place of a 2.5L in a YJ. Are the motor mounts the same? What has to be changed, I would swap the tranny also. ARe Xfer cases the same, NP231's? What about a 4.0L from an XJ into the YJ? Is this swap much cheaper than going Chevy 4.3? or V8? Anyone know for writeups on the swap?
