I recently bought a 95 YJ with a 2.5 L motor, and I can't stand how freaking slow it is, so I think I saved up enough money to get a new engine and drop it in. I am not really good around cars but I do have help from a few friends. I heard people drop Cherokee 6 cyl into YJ's, but not to sure I want to do that, like if it will even fit... Overall, if anyone could give me advice I will be very thankfull. I want a good enough motor to actually turn 35's and lift it. Also, is there any problems I may run into? such as cooling...ect.
