im changing the motor in my 93 zj ive found a very low millage 4.0 the guy told me it was a jasper crate motor im not sure i know the motors real clean inside and out the jeep it was in got hit in the *** but will that motor out of an xj fit in my zj? im not 100 percent sure but i was thinking that the motor mounts where different and all the externals where also, and are the trannys the same any help would work thanks

 

the long block is the same so the engine mounts should be the same so no worries there. id try and pull any #'s from the block and check w/ Jasper to be sure, other than that youll just have to swap over all your accessories, intake and whatnot and drop her in...

 

Call the maker, they'll know all this information
