Hello all... i am in need of an engine for my 91 wrangler... i do have to pass emissions ( bummer). i have a question tho. will i be able to put a cherokee engine in my YJ, up to 1995, without modifying anything. what about a 1993-1995 wrangler engine ? BTW.. its a 4.0 L I see lots of those for sale, but i dont want to have to do lots of modifying.
