obviously!) different standard wheels on later cars(lattice on early cars,sharktooth on later ones), 2wds have better front brakes(4 pots),2wd box is nicer to drive,more positive on changes, different ecu(l6 on 2wd l8 on 4x4)2wd has a tubular manifold and smaller turbo(only just) 4x4 has a larger more efficient intercooler.shorter manifold and no need for a turbo damper, 4wd has the stronger 200 block engine with a different water pump(2 outlets on the front) radiator has different outlet positions. ill try think of some more,thats just off me head,didnt know how in depth you wanted it?

Good answer!
Also: Late 4x4 Saphs had the emissions friendly (83 US standard) green top engine with Lambada sensor on the turbo, plus knock sensor and cat.
