I had heard of a couple of 107 SL 'little' V8s getting a stick in europe....Guess you learn something everyday...
Someone had something up at one point ('course I can't find it at the moment...
) that said MB didn't put a 5spd stick in a Turbo because of these worries. Just gossip for as far as I can prove it... Seemed to make sense...that was the same excuse they were flaunting in the 90's when they wouldn't put a stick in anything bigger than the six. That and the fact that I read a report that AMG had to tune down one of their recent models because the tranny couldn't take the torque. Supposed to have been taken care of that w/ the new 7spd.
Of course none of this answers the question of whether or not there is a manny that will bolt up to a 603. Did they ever put a stick in the 190D 2.5 Turbo? That was a 602 motor, might be similar enough. I know they put one in the non-turbo version, however hard to find they are...
Just thinkng out loud...
