With NOS I would get a prof install just to be really safe, its not like a regular mod you could very seriously damage or destroy your car if its not used properly. To avoid accidental damage to your car when nitrous is involved, dont use nitrous. Just IMO, if your willing to risk it for the boost then im all for it but its not a 100% safe thing to do.
