any way to get more power out of the 2.5 4 banger??
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.
Wot's...uh The Deal?
There's a couple of air restrictors in the filter box intake you can remove. It helps a little.

my 4 cyl has loads of power hahaha no im kidding it sucks esp with the stock gears that came in my 44s i think there like a 273? the worst motor ever put into a jeep was the 2.5 =)
a 360 or 350 for the yj..?? hmmm what do you think?
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
