im looking into getting a 2000-2003 s2000 and want to run nitrous with it. im pretty familar with how nitrous works but im finding a hard time find the max shot to run on a stock s2000 engine on 91 octane and how much retard to run. my first mod will be a aem ems and a nitrous system so i was wondering what are some of the largests shots you are running on stock engine with stock compression and 91 octane gas and any resonable amount of retard.
