So I have a 92 YJ. It has a hard top with full doors, rhino lining inside and out, and custom fabricated bumpers and rocker guards. It has a 2.5L motor in it, with about 185k on it. I have owned this jeep for about 7 years now and I'm tired of the total lack of any kind of power...it does good to do the speed limit on the interstate. Anyways, I've decided I want to swap the motor, but havent come to a decision as to what motor. I've been told that a Dodge 318 or 360 out of a 90's model dodge truck works well, I've also been told a 351W is an easy swap. I guess my question is for anyone that has done it, what's better? Fuel injected or carbureted? I am on somewhat of a tight budget so I need a happy medium of power, fuel mileage, and ease of installation. Also, with a small block V8 how much would I have to beef up the drivetrain if any?? Any input would be greatly appreciated. Thanks!
