^I'm with Rob, really to run nitrous you should upgrade your internals, thats goes with turbo aswell. It's safer and you'll get a better outcome. There's no cheap way to get the car faster and really the cheapest is to just turbo it like thermalfi'd said.
P.S. "please dont argue with me, your obvious lack of knowledge is already beginning to show" - I for one know Rob knows what he's talking so no more flamin
