Bearing Clearance for Turbo s52?

Im attempting my first engine rebuild on my s52 and I am trying to decide what size main and rod bearings to use. I am a little confused by bmw's color ranking system for bearings and I'm wondering if I stick to stock sized bearings. I am planning on polishing the crank and making eventually 500 whp with a turbo. I know polishing wont make a very large difference in the journal size. I also understand that some prefer to have more bearing clearance for more powerful engines. Do I get stock size bearing for the 500 whp and hope that the polishing added enough clearance for the power? Or do I need more clearance? Any help would be greatly appreciated. Thanks!
