I would choose a cam ground for turbo applications. A lot of the cams that are advertised with big HP gains come from high lift, high overlap, meaning the intake and exhuast valves are open at the same time, for longer. This is better for NA because the exiting exhaust helps pull the intake charge in. When you pressurize the intake though, any overlap is going to cause you to blow your exhuast gas out, and blow your intake charge out the exhaust as well. A good turbo/supercharged cam is going to have high lift, and very little overlap. I believe both Crower and Crane make turbo specific cams. Worth checking both of those out. Stay away from NA cams though. You'd very little if anything from runnning them.
