I think a '93 has the 3FE, so no head gasket problem. It's a dog, but it's a 3FE. If you don't mind going slow it looks like it definitely has potential.
91-92=FJ80 with the 3FE. Underpowered by anyone's gauge. None will have axle lockers.
................ None will have FF rear or rear disk brakes. 15" wheels
93-94=FJZ80 with the 1FZ-FE engine. 212hp all years that it was produced. 16" alloys.
.......... AFM fuel management. Forced induction is problematic.
.......... F&R diff locks available as an option. (~7%)
.......... Most will have rear disks and FF rear axles.
.......... Most will have leather, 3rd row, and the other options that are seen on 80-Series.
.......... A442F tranny. (aka the "bus" transmission)
95=FZJ80. Front air bags. Pre-OBD-II. A343F transmission.
............... MAF sensor for fuel management so forced induction is less troublesome.
............... All will have FF rear axles. Most will have leather,
............... 3rd row seating and the other options that are seen on 80-Series.
............... Revised interior, mainly the dashboard.
96-97=FZJ80. Full OBD-II. (Otherwise, same as 95)
There are many other differences but nothing substantial between the model years. Do not overlook the LX450s. These are the same as the LC except they have side plastic cladding which can be an issue if you decide to de-flare. I would jump on an LX in a heartbeat if one came available.
