BBC NOS Port injection
I'm new to nitrous, and plan on using it on my 454. I have an RPM AIr manifold that is plumbed/tapped for direct port injection. I have the fogger sytem (lines and blocks). Here's the question, I don't know what else (hardware wise) that I need to complete the system.
Will this be considered a "dry system" since fuel is still running thru the carb? Can I just buy a generic NOS/ZEX system with nozzles and selonoids to complete?
I don't want to use the throttle plate setup (although it appears to be much simpler) unless it is recommended as a better alternative.

You definitely got a wet system since you need to add your own gas to the mixture. I am not a fan of direct port injections because it involves alot of plumbing, nitrous jets are very pricy and you need 16 instead of 2 even for the intial testing.
With the plate system you can learn. You start out with small jets and work up as your confidence builds.
With 100 horse the plugs are stock, no dedicated fuel system, no timing change, no nothing.
Direct port is too complicated with 16 jets to change to learn how to use the system and work up slowly to a comfort level for you.

Thanks Norval for the sanity check. After a quick talk with NOS I had a rude awaking about the complexity and costs of this type system. I just didn't want to raise the carb any higher into the hood....and my manifold is drilled and tapped and I have the fogger block and lines. Still, with 16 nozzles to purchade and the rest of the hardware stuff, that's some serious $$ vice a 450.00 Sniper setup.

I am one of the guys who got addicted to nitrous and the huge power gains it brings. About three years ago I was in the same boat you are, posting a basic question about how, what, how much power, etc. Funny thing is Norval gave me the same answer he gave you.
Since then I have upgraded to a full race Fogger and Double Cross plate system on my 454 and am 1/3 of the way through a dedicated 572 nitrous street / strip motor that I will spray an additional 500-600 hp through two Foggers.
The reason I point all this out is if there is a chance you are going to want to run more than 150 hp or so through your nitrous system then step up now and get the Fogger done. Norval is right on when he says 100 hp is nothing, but more than 150 or so through a dual plane intake with a plate system, gets a little more difficult. This is due to the uneven distribution problem associated with dual plane manifolds. Nitrous exasperates this problem.
If you are looking for a deal on nitrous stuff give nitrous supply a call. It is run by the founder of NOS, Mike Thermos. I get all my nitrous stuff from these guys and not only are they very helpful, but they beat everybody else prices. 714 373 1986.
