I come from the world of VW where the same basic engine was used for 40 years to be replaced with the same basic watercooled 4 cyl that has been in use since 1975. Pretty much anything will bolt into anything with a couple of mounts welded up & some elbow grease.

The mercedes world is a bit new to me, and I keep looking for the parts interchanges, but don't find many at all. Is it just that there aren't near as many of them, or am I looking all wrong.

My main question is if a 220d transmission would fit in a 280s, so far it looks like a definite no idea, heh. Now that I found the online parts catalog I can figure it out pretty easily, but some intercanges aren't obvious from the manual.

Perhaps this could be the beginning of a reference thread where everyone posts every interchange they know of. Details like, how you found the interchange, what is it from, what it goes in, part numbers, chassis codes, engine codes etc. plus, other parts that must be changed, and why such a cross might be desireable... (i/e higher horsepower, more gears, better cruising rpm's etc.)

take care,

Jester
