You've got a LOT of reading young grasshoppah! You are afraid the Turbo kit won't last? It'll last a hell of a lot longer than the S/C kit if you don't get the upgraded jackshaft. On another note, PUT THE 2F2F MOVIE DOWN!! Here in the real world we call it Nitrous! NOS is the name brand, not the abbreviated word for Nitrous!! You may want to read up on a 3.0L swap, which can be conveniently found in the 3.0L Forum. 120K miles and looking for a rebuild = 3.0L. Best bet would be a 3.0L Oval Port from an 01+ Ford Escape w/ low compression pistons and upgraded conrods, with an ADC(Arizona Dyno Chip) turbo kit.
While you're at it you'll want to upgrade the tranny with a Quaife/Torsen LSD, a SPEC Stage III clutch, maybe a lightened flywheel and a suspension that can get some of that power to the front tires. Good luck, as the SEARCH feature is your friend.
