I wouldn't say NOS is a low boost setup.. Once u got a lot of oxygen in d engine, ur ECU will detect it tru oxygen sensor in ur exhaust & it will maximise fuel injected in ur engine..
Usually NA use a wet system meaning the NOS system itself has another set of fuel injector to support a surge of oxygen inside d engine to make sure d engine won't have a lean AFR
Furthermore, usually NA engine has a high compression ratio thus making it unsuitable for NOS
I can talk about this all night long.. But i got to sleep too
Long story short, if u r thinking of getting a NOS.. Forged internals n turbocharged ur engine 1st
Don't repeat other people mistake.. Search d net.. Lots of information out there
