The sc300 came in the n/a only with no turbo option in the united states. im not sure about overseas. the only v8 in a sc comes in the 400. as far as turbo goes, im not sure how hard it would be to build your own, but im pretty sure it wont be near as easy as an integra. and for pricing like always, it depends on alot of things. If you look around you can find these cars in very good shape for under $10,000 easy
