electric fan made a big diffrence, when you only got 100 horse(on a good day, and thats not even at the wheels) 2 or 3 extra seems noticeable. 4.0 throttle body couldnt hurt. ditch the a/c if you got it, thats another useless pulley to spin(unless you use it for an onboard air comp.). good distributor/or msd could help. fresh plugs. synthetic oil.some kind of better air intake, Id keep that plenum box on top of the t-body for volume. lost all my low end with a tube type(I put a cone filter thru the wall to the cowl and fabbed a metal box to keep water out) headers seem to kill bottom end power and thats what you need 80% of the time. just do the little cheap stuff as needed and save for a swap if you really want some cajones under the hood.
If you really want more power sell your Jeep now. Your profile says that you are still stock so if you know that power is a problem you should find a Jeep with a 4.0 before you start to dump money in the one you have.
I love my jeep dont plan on selling it anytime soon... if I wanted a bigger motor I would have put one in instead of completely rebuilding my 2.5... I was just wondering if there are any mods that I can do to it to help the power/fuel economy
