im buying a 2001 acura integra type r but i have a few concerns about one im buying. its got a b18c1 bottom with a type r head...im sure the b18c1 is from a gs-r engine and not the stock type r bottom. is this a good thing or a bad thing? - any reason why it would have a gs-r bottom instead of the stock type r bottom? or is it the same thing. has the car lost hp or gained or is it the same?
