I own a 99 Wrangler and built it from stock. This little 2.5l gets great gas mileage and now has 167 thousand miles on it. Over the past 5 years if done some work to it that has fooled many jeep 4.0's owners. If I new I'd be hooked on the jeeps ability off road, fun and reasonable cost of upgrades I would've started with a 4.0 but, I own it and now I'll just work with what I have. If others that own the 2.5 want more performance I may be able to help. Once I navigate my way around this forum I will add pics.
I live in Massachusetts but have a plan to move to Arizona and hope to meet up with a good club out there. I'll take any suggestions. Thx.
