Turbo a jdm lol what's the point. It's going to blow up anything over 8lbs of boost guaranteed. Turboing a high compression motor sounds like a pretty smart idea! Sleeve it then turbo and you won't have to worry. Plans for a supercharger are no different really. This prelude forum is the worst on the net, why I only post here about once every year. I laugh at some of the info passed on when it's not even correct to begin with!
