by your avatar you have a 2ng gen. i would either buy a donor rig or find a mostly complete truck or 4runner at the junkyard and take everything engine related (efi fuel tank, lines, evap stuff, coil/ignitor, wiring harness(engine and body harness) the entire engine even. then swap it into your 2nd gen.
my truck is a first gen. you can pretty much do the same thing although the gauge clusters, find a place to mount the computer that sort of thing. with the 2nd gens everything has a place because some came with the 22re.
