I think you need to give more information.

If you have chosen a system, you need to give the model number for it and the model number and year of your car.

If you have not chosen one yet, read about the various types of nitrous oxide systems, their pros, cons, and legality for your purpose. If you still have questions, provide as many details as possible about your situation and your car, and then ask for help with choosing.
