how hard is it to install nitrous?? - 6G Celicas Forums
when it comes to nitrous if you are not sure how to install then you should have a shop do it , that way they can tune it right the first time.
If you have never installed nitrous, I recommend having a shop do it because there are plenty of things that can go wrong. However it is possible to do it yourself if you are brave enough. just make sure your air/fuel ratio is rich and your timing should be retarded around 5 degress depending on how the car runs with it.
