4 cylinder jeeps

Ian,
350? i wish but it would require so much more to do it.
Its my wifes TJ now so we need to get it back on the road asap (as she is driving the rubi full time now).
i bought a TJ motor with 104 kms on it to put back in.

i agree that the reason the abuse of 4cyl engines is so extreme is because of the 4.10 gears. If upgrading to 4.88's than pushing the big tires on and off road would be much kinder toi the engine.
i was never kind. Even when i was running 33x9.50's for the winter to help out, the rpm's still ran pretty high on mountain highway runs to ski resorts.

Mike, Varsity did the rebuild of cylinder #1 at 130,000 kms. It was piston #2 that gernaded.

I have a 97 tj 2.5L with 31's and i believe its geared 4.10

Had a few times in the bush where it failed me but it was my fault haha.  I have gone up some pretty steep inclines and wasnt able to be followed by the 4.0Ls i was with. Perhaps weight difference and gearing helped me there though.

All in all I'm happy with it in the bush.

As for on the highway.....

Its not to bad on the highway. 5th gear rarely gets used especially with a headwind coming against you. As for speeds. I usually have no problems staying at 110 although if i notice a big hill coming up i usually gain speed because i know i will loose it on the way up.

The in city gas miles are better then the highway miles i get at least.

For the amount of highway driving I do, I kind of wish I had the 4.0L but in the city and on the trails, the 4 banger does just fine for me.

Well before I built the new inline 6 for my jeep I had a old worn out 2.5 in her.

I ran 35" tires all year and was able to keep up just fine    !!THE FREEWAY IS WHERE I HAD MY DOWNFALLING
It more or less comes down to other mods for off roading....ie tires ..lifts....suspension.....gearing.......and most of all the driver. I'm not the best driver but I learned alot haveing a small package under the hood. ....lol

It's not the size but how you use it......lol :lol:  :lol:  :lol:

I had not broken a part all year but spent a great deal of time fixxing others rigs.

Basically if your jeep doesnt clear the ruts .......you are going to get high centered ......regardless of how fast you spin those tires while they are not touching the ground........

I like the inline 6 alot for on road use but can't wait too see what breaks on me this year with over double the torque and the 74 extra ponys.


My 2 cents.................
