Can't get much more power without a supercharger or hemi engine swap.

Different gears help a lot. 4.56 and 4.88 both work. Engine runs a lot faster on the freeway though.

Bolt ons will not give you any rear wheel horsepower man. Save your cash. The gears will be the most noticeable change. Super Charger is what's up if you really want more juice. If you can't afford that, don't waste your time on the other crap that does nothing.

Thanks, gears are up first. I still will get the usual stuff, CAI, exhaust, programmer and maybe some odds and ends. To say if you cant afford a SC then don't buy anything?? All the bolt on stuff may cost me as much as say $1k, cheapest I found a SC was $5k; that's what we call a massive difference. Also I don't expect to put bolt ons and start running 10sec quarters but it still will give it a little something. Don't get me wrong,I would love to slap on a SC, but not on a jeep. (For now at least) :-)

That's the right attitude for JK engine mods. There are plenty of threads talking about all of the various bolt-ons, be sure to do a little searching and reading before you pull out the credit card.

And when you are looking at the numbers, pay attention to the fine print! 20 or 30 or 40 HP in big bold letters - but many people miss the 'at 5,000+ rpm' tucked way over on the side, and then they realize that they just spent a grand for 6 or 8 or 10 'usable' HP. The HP that is down in the rpm range most of us run in, not up at redline.

You could also check a few threads on the Sprintex superchargers (in the $2500 range) and Ripp long tube headers (in the $1600 range).

And when it is time to start looking at hemi swaps, be sure to check out the LS swaps as well.
