I'm running my s13 sr20det at 16psi on a BBGT3037. I'm thinking about running alil nitrous...maybe a 40-50 shot. How safe is this? My internals are stock and i plan to keep them stock. Fuel management is at 550cc, fuel pump, SAFC. Thanx

It sounds like you have the fuel upgrades to run a mild shot...

Why not just turn up the boost? Or invest in some cams.
