Best alternator upgrade for '01 TJ?

What's the best Alternator to upgrade the 117AMP in a 2.5L with a 34-AGM Duralast Platinum battery?
Thanks!

I'm about to upgrade a 2001 TJ, 117AMP with a 2001 Dodge Durango 160AMP. I'm a rookie; this is my first upgrade, but want to learn. Looking at the spec pictures for each alternator, they appear the same in terms of mounting posts and plug.

Will I have to upgrade the wire gauge?
Are there any other things I should be considering?

Yes you should upgrade your wiring, stereo guys call it "the big three"
1. Upgrade the charge wire from alternator to battery
2. Add or upgrade a ground wire from the alternator the the body
3. Add or upgrade a ground wire from battery to the body

Rewire if upgrading to 136?

Would I need to rewire if I go to a 136AMP? (Yes, I'm trying to avoid the rewire, but only because I don't know what I'm getting myself into.) Where would you put the rewiring on the difficulty scale?

Also...
Am I correct in my thinking....? The 160AMP alternator is a passive device that will NOT produce more amperage than is being pulled. So I don't have to rewire until I actually add new load (winch, AC, lights, etc.).

Also asking because what I ultimately want is a dual battery system and I think some of the rewiring comes with the battery kits. I'd like to swap the alternator for 160 right now because my 117 is shot, but wait on the rewire. Thoughts?
