that guy doesn't know what he's talking about, don't worry about it. For one thing, the B16 was a far superior motor than the "new" 2.0 liter SI motor, anyone who's driven SI's of both years will tell you that. And don't worry about blowing yourself to pieces, that kid has seen fast and the furious too many times. When installed and used properly, nitrous is a safe and very effective engine enhancement.
