you will never get the RE motor set up for speed. it's just a 4cyl. never pull your truck to 130mph w/o some seriously expensive internal upgrades.
common "bolt on" upgrades,
you can use a 20r head and a cam.

lif kits and body lifts are available for 2wd set ups. rough country, skyjacker, rancho and the like are all good.
visual body mods, i have no idea. but that's prolly the easiest for you to look up and decide.
cheers!
