I have a 94 yj and throwing in the rough country 4 inch suspension lift this weekend. I am going to go with 33s when spring gets here. Being that I live around alot of hills and the 2.5 forces to make them with my 245s on it I want to do an engine swap in the spring. I am really leaning toward diesel and preferebly a 6 cylinder. It is my daily driver and I do a lot of local towing (sleds, quads,campers and tool trailers) Any suggestions on the easiest, more efficient swap motor size and transmission/drivetrain?
