Zex Nos Kit Install Guide for Toyota Celica GT
Made popular through the first Fast and Furious movie, the nitrous oxide (Nos / N2O / Nitro) injection is the simplest way to provide a significant power boost to a gasoline engine.
The principle is simple - when N2O is heated at about 300°C (570 F), it will split into oxygen and nitrogen, so feeding such fuel to a combustion engine will provide it more oxygen, therefore more fuel to burn. Another benefit is that when the nitrous oxide evaporates, it absorbs heat and keeps the engine at a normal temperature during the hard work.
This guide on Toyota Celica Online gives a thoroughly explained step by step tutorial on how to install such a system on a ’94-’99 model Toyota Celica GT.
