ABW,
Don't forget the rotating assembly. Being at the very heart of the engine it deserves the parts that will go the distance, crank, rods, pistons, rings, etc. Fortunately the same cam that would get you by in a NA street motor might not be too bad in a turbo application. Consult I.I. experts like tlowe #1716, CNC-Dude #5585 and others. No substitute for experience except maybe more cubic inches.
Good Luck, Kalvjn
