My friend bought a 85 318 for a DD to keep miles on his other car down, but the m10 is about to go. He found ryans old eta motor and tranny for 200 bucks, but doesnt know if the small case diff will handle the torque. Should my friend go ahead and get a large case diff? It wont see any track abuse, just normal driving to work and whatnot.
