Nitrous, Super Chargers, & Turbos - NX or NOS??

I'm looking at 2 nitrous systems, both are wet style:

NX System:
NX EFI single nozzle kit w/ air intake tube style delivery up to 250hp, 15lb bottle, microswitch activation
jet sizes vary by engine displacement
Part #: NEX-20923-15


NOS System:
Sportsman Fogger intake mainfold style derlivery up to 250hp, 15lb bottle, microswitch activation
50, 75, 100, 125, 150 jet sizes
Part #: NOS-05030FI15NOS

Ok so they are basically identical except for the delivery style, so my big question is which style is better, air intake or intake manifold???
I should add that the prices only vary by $15 bucks so price isnt a factor here.

mm...peice a nitrous system together yourself. just make sure to use NOS solenoids

like a turbo kit...a nitrous kit will be more expensive than peicing a system together yourself

So which style of delivery should I look into? air intake or manifold?

btw...the reason i say NOS solenoids is because NX are known to fail...but in general NX solenoids will last longer

it doesnt really matter which one you go with...theyre both 'wet' setups

ahh ic so theres really no advantage to either delivery system because they are both wet?

more or less the same. btw dont take my information as fact...but im pretty sure im pointing you in the right direction. i am by no means an expert on nitrous

I started building a kit, and the price got close enough to the actual kit price that I'm just gonna pick up a kit, I'm a complete newb when it comes to nitrous so I'll fork out the money for a kit, makes sure I get everything I need. This is still a year away at least, but I'm the kind of person that needs to plan things out to completion or I won't get anything done.

just make sure you do some research before getting a kit. i havnt researched it much myself because i dont plan on putting nitrous onto my current car. its prolly gunna be on one of my future cars tho

I've done my homework, I'll prolly get the kit before I do my bottom end engine internals so I'll run 75 shot, after I get bottom end I'll up it to 125, then once I sleeve it, 200-250.

Here you go:
1. Fuel solenoid (NX or a large NOS)

2. Nitrous solenoid (NX or a large NOS)

3. Solenoid mounting brackets (Ebay)

4. Plate (Ebay)

5. Jets

6. Braided line from solenoids to plate

7. Fuel pressure safety switch

8. Nitrous pressure gauge

9. Fuel pressure gauge

10. Braided line to trunk

11. 10 lb bottle (Ebay)

12. Blow down tube (NHRA requirement)

13. Bottle brackets (Ebay)

14. Bottle warmer

15. Various AN fittings

16. AN fuel filter

17. AN nitrous filter


Optional:

Remote bottle opener (useful for running nitrous on the street)
Purge (useful for consistent runs)

[edit]Almost forgot to answer your question. A wet kit is basically the exact same as a Direct port, it just branches off into 4 jets instead of one. Theres really no excuse to not do a direct port other than just being lazy =) You can also inject the nitrous directly into the injectors with some setups.

Hey thanks thats the best answer I got yet.
