wow small block huh...never heard of that being done but always a first for everything...i remember someone on here having the Y8 turbo'ed, think he got pretty good numbers from it...but me personally i'd go with an engine swap, a b18c or jdm type r would give you some nice power out of the box...b16a is a good choice also if you want to build from bottom up for lots of power since they somewhat lack torque, but that goes with most factory honda engines. H22 can be done just would need mount kit and could get costly, dont know havent really researched it all that much, but H22 would be good for straight roads, since its a bigger engine you'll be putting a lot of weight to the front and a better suspension might be needed for future
