Switching my jeep's 2.5L L4 Engine with a 6cylinder 4.0L
 

I have boughten a 1992 Jeep wrangler last year and love it. I drive it
around alot. it has approx 155,000The only problem i have is it seems to be
under powered. It has a 5 speed transmission but overdrive is useless in it
because it doesnt have enough power. Then when i drive it in 4th gear at 60
it is up to 3 1/2 grand. I was wondering if any one knew if i should just
rebuilt it or if i should find a bigger engine. I have looked around and was
also wondering if i would switch the 4 cylinder with the six if i could use
the same transmission and engine mounts and everything eles.

This engine is designed to run at 3500 all day, and it won't hurt it. Fifth
gear is indeed useless. Once you get used to that, you will realize that
the vehicle is driveable. The swap you are talking about is possible, but
the transmission will have to be changed. Unless you find a wrecked six
cylinder vehicle of the same year or close, and free labor, it is probably
not worth it.

Or go with a taller gear in the diffs. That will give you better acceleration
in 1st and put you in 5th on the highway.

That's what I did. 33" tires and 4.88 gears. I run 5th all the time --
start running 5th at about 45mph, depending on if I need to accelerate
faster.
