Just been a bit silly now, but would it be at all possible to fit a different transfer box to a cav/cally turbo(or GSI 4x4) whilst retaining the standard gearbox?? just a thought say Audi TT/S3 or even Mitsubishi Evo???(both transverse mounted engines so got to be fairly close???) As I said silly thought, possible cheaper in long run and better transmission losses???
