You didn't get an answer to one very uncommon problem. Hell, I've never even heard of someone trying to put a MPFI setup on a CJ 2.5L. How does that equate to no one running a 4 banger? Please do a search before you make an ignorant blanket statement like that. You will find members who have tackled many performance upgrades. Some with good results, some not so good. Ask and you shall receive, we are more than happy to help.
