Honestly, if it's not in a race setup I wouldn't bother. When you think about it, the best way to use nitrous on a 4cyl. motor is direct port injection, in which case you are basically looking at building a bottom end with stronger internals, which basically means while its apart you'd want to set up a turbo which is what you should've done right off the bat. So, without extensive work to the motor your best bet is a plate system ie. throttle body injection aka dry manifold or wet manifold injection, which is more or less a waste of time for the cost and little power gain. You're talking even with a 40-60 dry shot you're looking at having to upgrade the fuel system, probably narrow the gap on your plugs and would probably always have to run 92 octane. No thanks. I only run No2 in my Daytona to spool my turbo, as you can make a lot more power with boost than nitrous when it's done right. Just my .02. Did I miss anything Rabbit?
