Hey guys I am thinking the time is nearing....with a 15 year-old //M3 and 220K on the original engine a little valve tick is telling me to freshen things up!! Everything runs beautifully right now. Maintenance is nearly impeccable. Everything works. My mommy always said if it ain't broke don't fix it....but now as I begin to drive the vehicle harder with daily driving, track time, and longer road trips I wonder how I should go about a partial or full rebuild. Thoughts?? So far I have talked with Pat Kummrow of Kummrow Automotive in Milwaukee. He is great. I am told that perhaps a simple valve job with some porting, VANOS rebuild, and cams is the way to go. Selling my stock '95 cams to offset cost is an option. Then I am aware that going to the 3.2L bottom end with the OBD-I top end is a great way to add power through displacement. Ideas? My overall budget here is around $4-6K...what would YOU do? Thanks in advance for your feedback.
