you can fit a 2wd sump directly onto a 4x4-engine, but you need to grind some alloy away so that the oil-spray-bars dont rub againt the sump.

as above, 2wd enginemounts with brackets to the engine.

the iscv is the same, is the wires on the TPS that needs to be changed.

the coolantsensor for your intrument is at the same place as the coolantsensor for the ecu.

also the water-hoses arent the same, but change to 4x4-system, much better. need a new header tank for that.

wiring is also diffrent.
