It's not so much how big the cam is on turbo vs. blower cars, it's more about the lobe seperation angle (LSA). A higher LSA gives you a better idle but usually not as much top end potential (unless it's a custom grind like mine) and a lower LSA gives a lumpier idle with more top end capabilities. For a turbo something in the 113-115 degree LSA area works best usually while blowers like something in the 108-110 degree LSA area. This is, of course, mostly from my knowledge of V8s. The numbers might be a little different on smaller displacement motors, but the same principle applies.
