Yep!
Civic's run it all the time to eliminate the turbo lag from big turbo's (higher boost). Typically, they are operated by a control box that turns 'em on at 3000 RPM, then off at 6000 or so, once the turbo is spooled and producing boost. Some even have Manifold Absolute Pressure (MAP) sensors that shut the nitrous down once boost is present in the intake manifold. On most civic's, I see a semi-wet system: 4 Fogger nozzles are installed on the intake manifold tracts just before the intake valves. Both fuel and nitrous are injected (or 'fogged') through the nozzles, so there is little chance it will condense on the intake walls. It's a totally "stand-alone" system.
Quick Info:
Wet System: Fuel and Nitrous are injected through a single nozzle just after the throttle plate. Only way to go if your bike is carb'ed.
Dry System: Nitrous only is injected through the nozzle after the throttle plate, the extra fuel is supplied by increasing the pressure to the fuel injectors, which may be stock or aftermarket. Cannot be installed on a carburated bike / car.
