    2.5 liter woes...

    I've got a 2.5 with 31" rubber.......I've added a throttle body helical spacer and headers. BIG difference! Can actually do 120 on a hill! Have the converter checked too!

    they are very reliable depending on how they are driven .200 plus km is very common .

    Hey guys,

    I had a 4cyl in my rig for 9 years and wheeled it almost every weekend and it was my daily driver. It never let me down and was always very strong. Don't forget that's what real JEEPs started out with. What was in a Willy's = 4cyl. The last three years of my 4cyl life it was pushing full size axles, 35 Boggers and steel beadlocks with metal hanging off of every side and corner of my JEEP. I also never broke anything. I only took it out because I always wanted a Gen III V8 Vortec under the hood. I almost wish I still had the 4 banger because all I do now is break shit!

    Long and short the 4 cyl kicks ass.

    L8ter, Jay
    Work hard but play harder!

    '95 YJ 2.5, stock tranny and T-case, stock 4:11 gearing.
    I've installed a cold air intake and did an electric fan conversion to get the most out of the engine's minimal power.
    Super 35 rear end upgrade, locked front and rear, lots of lift and running 35X12.5 Krawlers. Daily driver and competent trail rig.
    Ya, I don't have a lot of highway speed, but it keeps up, and so I have to gear down when going up a long incline, but so do 1000's of transport truck drivers, lol.
    The engine in this thing has been bulletproof.
    It currently has over 270,000 kms on it.

    '95 YJ lifted and locked.

    The 134ci "Go Devil" put out around 60 horsepower.




    You're right, Jeeps traditionally weren't designed to go fast. I'm satisfied with my 2.5, even with the never-ending razzing I get for it. I abuse it like a red-headed stepchild and it always runs and can't really break axles or anything.

    So I installed the flux capacitor but the Jeep just won't do 88 mph.

    I agree, I love my 2.5, 210k and still going strong. The best tank of gas I ever has was 550km for the tank, I'd like to see a 4L get that. And it's completely stock, no electric fan or throttle mods. Synthetic fluids have definantly helped alot.

    I have a 1999 TJ 2.5 and so far I've gotten to 410km/tank. How'd you get as high as 545kms? Is it a stock set up? Are you running a manual transmission?
