The W box should be pleanty, wou will probably want to run a F or G series, G series come up cheap and heaps of ratios but same for F series but don't seem to be as cheap when they do come up unless it's the one that is about 20-30mm a side wider, my hilux is only 10mm a side wider than a T series and cost me $250 to buy the diff and put mounts on it.
