I'll work on the pictures when the tornadoes blow out of my area. It was originally 4wd and we ran it that way for a long time. We changed the transmission about 6 months ago and went 2wd because we never really used the 4wd. Both 4wd and 2wd transmissions were T5's out of a chevy. We used the original factory AC and Power Steering. All brackets were homemade. Also, it uses an alternator that originally came in a chevy luv because that particular alternator has a vacuum pump on the backside. the turbo housing is orginal (Frito Lay Step Van), though the insides were swapped out of a turbo off of a Komatsu 4B. That helps produce boost at lower rpm. I get good power and boost starting at about 1500 rpm. We used the original 8.8" rear end, but I swapped the gears from 3.27's to 2.73's out of a mustang. Seems to be ideal gearing for this vehicle. I get 32 mpg and am only running about 1850 rpm at 70 mi/hr. Most everything else is original explorer. With the original fuel tank, but all the stuff taken out of it, it holds about 24 gallons, so I can comfortably go over 600 miles between fill ups.
Thanks for the interest. I'll answer as many questions as I can. My plans for this summer are to remove the engine from the explorer and install it in an '01 quadcab Dakota.
