I think maybe if you had a 3" body lift and the 3" suspension lift + trimming the fenders you might be able to get away with 33's under there but I would imagine that you would have to use 33x10.5 or 33x9.5 tires under there for very clear reasons, and to have them turn at all you would most likely have to put them on 7" or 6.5" rims, and 15's would most likely be your rim diameter. And then once you have that all done you have a guttless wounder of an engine trying to run those things, the only way to run them would be to either modify your stock engine a great deal, or go with an engine swap, and with that option you only have a few choices as far as engines that will fit in a 4x4 Luv, which limits you to either a 4DE1(2.3L,caburated, came in 1984-1987 Troopers, and 1991-1994 Amigos), 4CE1(turbo out of a impulse i believe) or a big ol' 4ZE1(2.6L, fuel injected, came in 1988-1991 Troopers, 1991-1997 Rodeos, and 1991-1994 Amigos), there is the idea of putting in the 2.8L V6 that came in 1988-1991 Troopers (It's accually a Chevy engine that is in there, but it's connected to an Isuzu tranny, manual tranny that is, i believe the automatics that Isuzu used where Chevy TH's) or the other idea of putting in the 3.1L V6 used in the early Rodeos, 1991-1992, (same deal with the 2.8L in the first generation Troopers, Chevy engine, Isuzu tranny, except for the autos, which where Chevy units)
well i hope that help ya a little, or at least give you an idea of what it's going to take to make something of that sort useable
