First, I would not build anything as I see in Xtreme 4X4; I have seen them do many wrong things in the past, and they have unlimited budgets for most of their projects. Having said that, I have seen a Jeep with 4" lift and SOA, but I would not recommend it. It is simply TOO TALL. This makes the jeep very unstable. The most I would go would be 2" lift with SOA, and lots of triming (including flat fenders), and maybe even a 1" BL (I'd never go higher on a BL). That should allow you to fit at least a 37" tire, most likely more, while keeping the Jeep as close to the ground as possible (this makes the CG lower, reducing the risk of a roll-over). but that's just me, the guy whose final goal is to put 33" tires on his rig... Then again, 33's and good driving can get you through most of the trails out there!
well, like ive alwasy said, to each his own.
now, for the itty gritty. i did the fuel tank mod. took all of about 10 minutes with 2 trips to the garage because i was to lazy to pul lthe jeep around back and just worked in the street. haha. im going to do the 4.0l throttle body, new exhaust with a header possibly, new injectors, air-aid TBS, home made PVC intake with a K&N, and some ignition work and larger plus gap. that being said, i have some questions:
if i got to advanced what do i need to buy?
what year and model injectors?
what 02 sensor should i get? where to i get a wide band if i need one?
what are some good ignition upgrades i can get that will bolt it?
also, my jeep will idles high, about 1500rpm's and if i let it sit for about 45 second to a minute and not touch that gas, then its will settle at about 800rpms's. but if i barely touch the throttle, roooom, right back to 1500. what do i need to do so when im coasting up to a stop sign, or stop light, by the time i get there, it has setteled down? thanks everyone for the help! this site is great.
