Who wishes chrysler kept the 4.0L?
After driving my g/f's 04 TJ the other day I must say it made me realize how much of a dog the 3.8 is. Her's an auto too!! My 08 is a 6spd.. Even with my superchips and stock 32's it didn't feel as powerful as her 04 TJ. All the more reason to re-gear!! However I kind of wish Chrysler had skipped the wimpy 3.8 and retained the 4.0 inline until 2012.

That said, my 2003 Rubicon with 33's was a dog on hills. I believe the 4.0 went away due to CARB/Smog regulation issues but I could be wrong. I wish they would just drop a V8 in there and be done with it, but it won't ever happen.

I got to love this dislike of the 3.8 liter. The jk not line the jku is larger and heavier than anything the 4.0 L handled. Have the complains are so stupid. The 3.8 does its job well. It can handle the jku well. The extra HP in the pentstar engine is not going to make any major noticeable improvements with the 4x4 gearing.

At first I thought, man my 4.0 was way better, then I realized, it's not the 3.8 that's the problem, it's the gearing it's mated to and the additional weight of the jk.
