I have a boat that has less power than my liking and also have an m90 supercharger off of a gm 3.8l Buick park avenue that through a rod. My only costs would be charge air cooler and pipes, belt/pulley assemblies, and possibly a car intake manifold to eliminate one of the two carbs. I know this has been done before but can?t find a detailed parts list and am looking for as much knowledge as possible to avoid as much down time as possible. I know this isn?t a boat thread but the supercharging process should be very very similar.
