I have a 323is and I'm getting together the parts to stroke it out and turbo it. So far I have the M54B30 zhp bottom end and intake cam but all I need to complete my top end is the S52 exhaust cam. Willing to buy both S52 cams as a set if priced cheap enough. I'm located about 2 hours south of Chicago and I can cover shipping if it's too far for me to pick it up. Thanks.
