Hi,
Aggressive cams designed for normally aspirated engines don't work well with turbo's. Get a turbo grind if you want to go that way. Stock cams work fine with turbos and you don't have to rev the guts out of the engine to develop good power. A good system should give you good and smooth power from low revs. Back in the early 80's I was racing turbo cars with draw through carby's. Prior to going turbo I had a hot 2.0 litre escort engine bored oversize with machined 202 Holden pistons, hot cam ,headwork and twin 45mm Weber carbs. This got reved to 7300rpm and rebuilt every 6 months. After changing to a Garret turbo with a single draw through 45mm Weber carb and a stock camshaft, this engine put out twice the HP and only needed to be checked every 12 months. I had stripped it down after the first 6 months as usual and found that the wear and tear on the engine was nothing compared to the higher reving normally aspirated engine. With the turbo I didn't go over 6000rpm as max HP was in by 5500rpm. Double the power and less maintenance.
