As far as aerodynamics through head and exhaust goes, why is supercharger any different than turbocharger? My understanding is that a supercharger is a direct drive compressor of some type, whereas the turbo is aerodynamically driven. In both cases you're forcing more air through the engine and in both cases you switch from negative to positive pressure on the intake side. Other than the much faster response of a supercharger, I didn't think there was much difference. Neither do I understand why a B21 is more amenable to turbocharging than a B20, but I have to admit I'm a rookie :(
