morning people i am currently rebuilding my 328i which is in the projects section. i am thinking about trying to source some us m3 cams however i dont know much about them... so a couple of questions.
which engine code is the us m3 engine? ive heard it could possibly an s50? could someone confirm.
also is any headwork required for the to fit or is bolt in??
and also what sort of gains could be expected?
and finally any good place to hunt for them? and a possible price..
cheers in advance adam
