i was the person who imed u, id suggest a zex dry kit not wet because ur manifold is not made for fuel (too many angles and places for it to pool up, unless u plan a forced induction system). for only a 75 shot id run zex colder spark plugs and id retard the timing about 2 degrees. anything over a 75 shot ud need a better fuel rail, regulator, pump, and injectors. a complete nitrous setup involves about the same as a forced induction system. dry systems and direct port are used for Naturally aspirated cars.
