You also may want to insure the internals will support this camshaft. Our cars have the E32 version ( http://en.wikipedia.org/wiki/Mercedes-Benz_M112_engine ), the others have a different version of the M112. You may buy a cam that will not work without a few internal mods. I am not sure the lower end (block) is identical, maybe you should check a lot further, seeing as you seem to have a coupe?
