I drove a '90 TBI 2.5L around for almost 9 years on 33's
I loved my Jeep, but always dreamed of having more power.
I started saving parts for a 5.2L Dakota/Durango/Grand Cherokee/Ram engine conversion.
I got rear-ended in December, my '90 YJ was totaled.
I replaced it with a '93 with a 4.0L and 3:08 gears
I was VERY impressed by this new-found power.
I swapped my axles and wheels/tires and lift kit from the remains of my '90 (this gave me 4:10 gears, 33's and 3.5" lift).
I will NEVER again buy a Jeep with a 2.5L the difference is night and day, its a whole new animal. A MUCH more enjoyable driving experience.
I destroyed my D30 racing a Cummins.
I WAS RACING MY JEEP! it is that powerful!
Swapped in an 8.8, (same axle I was planning on swapping into my '90) and now I can chirp first, econd and third gears.
I still have the Trans and bellhousing I (was saving for my 5.2L swap (NV3550)).
The 2.5L is a great engine if you just want to drive, its low RPM torque is good for off road.
The 4.0L does everything the 2.5L does, but SO MUCH BETTER its unbelievable!
You can see both my Jeeps in the threads linked in my sig.
You can see all the mods done to both, and what went from the '90 onto the '93.
You can watch my progress, see the damage, and see the new one grow, and continue to grow as I am always working on it as all Jeepers do.
