Nitrous Oxide Engine - Street Legality

Street Legality

Nitrous oxide injection systems for automobiles are illegal for road use in some countries.. For example, in New South Wales, Australia, the Roads and Traffic Authority Code of Practice for Light Vehicle Modifications (in use since 1994) states in clause 3.1.5.7.3 that The use or fitment of nitrous oxide injection systems is not permitted. Nitrous is legal in street driven automobiles, only if the feed line from the bottle is disconnected or if the bottle is dry (empty) or simply closed.. In Great Britain, there are no restrictions on use of N2O in but the modification does have to be declared to the insurance company, which will undoubtedly require a higher premium for Motor Vehicle insurance or could refuse to insure. Regulations in Australia vary by State, but is banned in New South Wales.

In Germany, despite its strict TÜV rules, a nitrous system could be installed and used legally in a street driven car. The requirements for the technical standard of the system are similar to those of aftermarket natural gas conversions, especially for the gas bottles. Since the car still has to meet its emission standards, which depend on the cars year of construction, its easier for older cars.
