The biggest problem spraying on a honda isn't how much nitrous it can handle. The biggest problem is that people who want to use nitrous don't want to spend a lot of money and either use a single fogger dry system or a wet system. The reason this is a problem is because stock honda intake manifolds have an air bias problem that starves cylinder #3, which will fry the rings first if sprayed on frequently, or too high of a shot. If you want to spray often, or higher shots, direct port is your best option.
