Porsche introduced the 3.3l turbo cams in that profile because of the inherent problems they had with turbo lag. The cams had lower lift to increase the port velocity at lower RPM's to improve torque.
Just like normally aspirated engines, you must match your cams to your induction system, namely the turbocharger.
Turbo cams have very low overlap numbers. You will lose a lot of potential HP by installing high overlap camshafts, Definitely a no, no.
