I know a 5 speed manual belhousing out of a Lexus IS300 or SC300 combined with a w56 trans would work, but I don't think it could hold up to the tourque your 2jzgte is putting out.
Maybe a auto trans from a supra or Gs300 combined with t100 trans parts to get 4wd and maybe the Inchworm adaptor?
Not too sure, just throwing ideas out there....
