no, it will be dangerous to use Nitrous Oxide in 800cc or 1000cc cars, ideal is above 2000cc or 1800cc, Nitrous Oxide enters the engine and ignites faster than oxygen from air so the car recieves an extra boost, and NOS is just a company, u shud say Nitrous Oxide, and hey i have seen Nitrous installed in modded baleno and Civics myself, it just requires a bit of experience and a hell lot of safety.
