Actualy I dont use nitrous.
I have in the past. The nice thing about the smaller turbos like a evo316g is they spool almost insantly and make real good power. Enough for most people. The nitrous comes into play if you want say another 50-100hp with out loosing the great spool up of the 16g. I rarely came across a car that i need the nitrous to beat. But it was there if I needed it.
I have since gone to a larger turbo with no nitrous (for now).
I am now using a methenol injection set up and dont want to use nitrous with it.
Plus the class i want to run in doesnt allow nitrous.

I also never said nitrous was cheap. Nor did I imply I wanted to argue about anything.
I have no interest in argueing. I just like to inform and educate.
I have seen more people blow their motor on large turbos than nitrous also.
