My thinking was to get a new 6spd out of a 2005+ w203 sedan and fit that onto my M111 block.. but I dont know if the tranny housing have the same bolt pattern from the M271 motor to the M111 motor.
the W203 2002 6spd still feels a lil slopppy.. but the 2005+ w203 6sp is very nice and tight.
Resurrected from the dead.

I am about to attempt this, My 98 C230 recently blew the headgasket (gofigure). I have a 2002 c230k sport coupe with a 6spd thats smashed on the side for a donor car. I plan on pulling the motor and trans, and seeing what i can do to drop them into the 98 c230. From what i've read, the w203 manual pedal assembly should still bolt up to the w202 floorpan. The big part is going to be how, to get the m111.981 which only came in the 02 C230k's to run in the chassis. I have a 99 c230k Parts car that i can pull the ecu/eis/key etc from if need be. I'm hoping i can run the motor of the 02's Ecu and get the wiring to match up. We shall see though.
