Actually, I didn't see the rest because I didn't look closely enough...
S-AFC, I gained 9 wheel horsepower on the dyno when it was tuned correctly; I had a few more parts than you do currently tho. The S-AFC does nothing for nitrous, it only works for your daily driver setup. Don't expect to use it to "help" your nitrous, tune it without spraying.
The Eclipse pump is okay I suppose, but the injectors are 100% useless. They fit the fuel rail, but they do NOT fit the intake manifold. You have to get custom injectors to make it work; the mods you have do not necessitate bigger injectors anyway.
BBIM/BBTB is fine and dandy, it will help more as you bolt other parts on. The Elantra 2001 intake cam will be nice there...
All in all, you'll probably be around 175whp while you're spraying the 55 shot, add a bit more for a 65/75 shot. The single biggest thing to make sure you've got is fuel with the nitrous. Bigger injectors can help this situation, but you'll need a way to "dial them out" for when you're not spraying and then a way to get them moving again for when you're on the spray.
At that point, it's almost easier to go with a wet setup. As much as I don't like a wet system, it would work better for your "intermediate" nitrous usage.
If you were going hardcore 100+ shot, I'd suggest you go direct-port with paired nitrous and fuel injectors per runner. Nitrous Oxide Systems make these cool little paired nos + fuel nozzles that can be placed at your intake runner seperately from your stock injectors. You'd have to have the holes machined into your manifold, but overall it's a superior setup both in terms of power delivery, safety and consistancy.
A nitrous progressive regulator and a wet direct port setup can allow for some severe-duty nitrous usage. I've actually given a little bit of thought to such a setup after the turbo is done, just for that little bit of extra hidden whupass <img src=/images/forums/snitz/smile.gif width=15 height=15 border=0>
