http://www.1300cc.com/howto/how2/NOS.htm For your nitruous needs.

 

u can use any size nitrous jettings as long as u follow these 2 rules:

- u jet 3 levels higher for the fuel
- u have the supporting mods for the specific nitrous level

that being said, with minimal fuel and mods, a stock n/a can run 50hp...but start getting above that and ull need more things.

 

I have a 60 shot on mine works good
