I have a 91 SI 4WS with a B21A1. I want to make some power, but something different than a turbo or super charger. How much nos could be ran on it?

I don't have much experience with NOS, but I was able to google and find several calculators on the web that might help you. Also, there is a QA here:

Seems like sizing starts with determining how much extra power you want on hand. This value is chosen within reason based on the amount of extra load the engine will take.
