Well I didn't think Grannyknot aught to be the only one trying to shoe horn unusual hardware into an S30. What about trying to shoe horn a 4 wheel drive RB26 in. Do you think the front could be converted to all wheel drive? What got me thinking this craziness was seeing an engine for sale on Ebay. It has a transfer case with holes for output shafts to the front wheels. I guess you would have to find a vehicle to source front hubs from 

I think someone has done this over on hybrid z. I can't remember the guys name .

That would be an interesting thread to see
