nitrous + JRSC is a bad combo, not because of the n2o eating the rotors, but with a wet kit, the gasoline can eat the rotors, especially when they get really hot after a couple hard runs they could possibly preignite.
I've heard mixed results tho. Some people say the wet kit shot is in there too short to do any harm, but over time and many sprays, it will eventually deteriorate ur rotors. I did a lot of research on this beacuse i wanted to run a 30 shot with my JRSC 6psi setup.
Check out this FI Integra forum. There's a thread somewhere from like a month back about JRSC + Nos. Just search for it. Those guys on that forum are hella helpful in answerin any questions, and tons of topics have been covered in their archives.
