what section to post a non s14 engine swap for sale?

[flyboyx]

I have an s52 that i would like to list in the classified section. i didn't want to put it in the m3 parts only area as i am pretty sure i would be wrong, but i can't find another section it would fit into. can someone please help me out?

Should be in the Off Topic Section. Try Bimmerforums and r3vlimited as well, it will probably get more exposure there.
