Well, if you buy a Dynojet jet kit, it comes with all the jets you need. Including the directions that tell you what jet to use depending on your sea level, and what stage you want. But if you want to save a little bit of money, and buy just a single jet and needle, Im sorry, cant help. You will have to do some research. A Dynojet jet kit only costs around 50$, not much.
