I think your tranny would be the ax5, not the ax15

I'm going to be doing the same,... i dont see any probs,.. other than 5th gear torque,.. probably going to be useless

I've seen the 2.5L - 4 bangers YJ's running 33's and 35's.  Depends on how you wheel it...

I have run a 4 banger with 31s and 33s and stock gearing.  31s are definitely very doable with no problems to anything.  However, going to 33s was a big difference.  No so much in the city but on the highway it sucked big time.  I rarely got into 5th and spend most of my tire in 4th and sometimes 3rd.  Offroad was still decent with the 33s and 4.10s. 

With the 4 banger for any tires bigger than 31s, you probably should look at regearing.
