I tried the search but couldnt find out what else is needed to do a m50 manifold on a 97 m3.Is it just a bolt on.Has any one done this that can tell me what else I need thanks.One more thing I was thinking of putting in the 540 hfm also.does that plug right in my old port or do I need to rewire it thanks.

Thats a good write up of the manifold.

You cannot just plug the HFM in, you will need a program made for the HFM, the only people that make it currently is dinan. AA tried and tested the HFM on OBDII M3's, it doesn't make power.

thanks for the site.I know you need a chip jc has new software for it.I just wanted to know if the hfm will just hook up without changing stuff.are you sure aa tried it with the m50
manifold .turner claims 300 hp with all that and some cams.

Yes JC has software, but its part of the cam kit.

AA's car had an s52 manifold still.

The hfm will just plug in.

With the JC cam kit for $3k you will make 240-250 rwhp.
