I have one that looks cooler and works. NX's jet map worked out perfect for me at 9.5 PSI. The secret is to set the jetting using a flow gauge not peak pressure. If you do that it will work wonders for any kit! Overall I put 200 and 300 single stage shots through it with no problems. With the specs that you have on your motor there is no reason that you shouldn't be able to run like a bat out of hell, if not faster than I have with mine at least.
I am using one on a carbd 96 s-10, with the rail upgrade. Running the motor and spray of one a1000 pump. the regulator for the n20 is a aeromotive 5-12 psi unit. I have the adjustment screw turned all the way in ( max press.) probibly like 11 psi. I have it jetted for 200 and use a progressive. so far I have only hit it with 75% or 150. and went from 12.7@109 on a hot day to 10.94@124.9. The best the truck has done on the motor is 12.12@115.6 tho. I love the setup works great for me. Just make sure to purge the fuel before any runs if you do not have a return line for the fuel supply to the noid. Lean spiks are bad. Did I mention that I love this kit. Just like all NX stuff in my opinion...great.

They are a bitch to change and located too high in the runners technically speaking. Shouldn't be too much of an issue, but NX wants you to have the nozzles way down by the injectors. If you look at the FAST intake and mine you'll see how low they really are in contrast.
Plus, when I did mine the first time in all hardlines I tried getting it to fit that way and it wouldn't. An ARE K-Member with Spohn solid motor mounts pushes the engine up another 1" for some strange reason. And that takes all the room away from getting the plumbing to fit in there.
In all honestly I wish I would have done mine using SX2 rails (the ones with fuel and nitrous in the same rail) on each side. Then I could have run a smaller 5" long line all equal length off each side. There is a picture of it in here somewhere and I think it looks way better then mine. Probably a lot easier to install too. I noticed something familiar in the way they mounted the rails though. It looks very close to the mounts I made up for mine! You should go dig that picture up because it is a very trick setup.
I do enjoy the 30 minute jet change! And NX's service (as well as Nitro Dave's) is awesome!

I have customers using the efi set up.They work well unless you are trying to spray a real large shot.On a large shot it is to demanding for the fuel system to move enough volume at one time for the motor and nitrous.

I gotcha Dave. BTW...I got the Direct Port yesterday. Thanks a bunch for the GREAT service.
I am going to be using a 1 gallon fuel cell with a Mallory 60FI fuel pump and A Mallory EFI regulator. That pump is supposed to be good for 500+ hp alone. So I am thinking I should be just fine spraying the 200 or 300 shot at the pressure and jetting the jet chart states. This will be independant of the cars fuel system.
Actually I may start with the fuel pressure regulated on the high side by 5-7 psi and see what happens.
Any other tips are appreciated?

Al,
Run a return line from the regulator to the fuel cell.This will keep the pump from cavatating.What it is is a holley regulater with a plate fitting drilled and tapped into the side.You put a 14 jet in there so it does not flow alot.This will keep the air out and from burning the pump up.We have them in stock already made, if you do not want to mess with it.

Since you're considering a seperate tank anyway, why not run alcohol? That's what I'm doing.
Methanol is 101 octane, but more importantly, the power penalty for running rich is much less than gasoline. With gas you're stuck between a rock & a hard place (too rich = no power, too lean = no motor). With methanol, too rich just means you use more fuel.
For purposes of detonation, it's as if your engine was a couple compression points lower (IE: 8:1 rather than 10.5:1).
Methanol makes more power per unit of oxygen than gasoline, which doesnt matter so much with a nitrous motor, but it's pretty nice with a NA motor. Methanol is also a great intercooler (better than water, and much better than gasoline), but this doesnt matter too much for a nitrous motor either but being a forced induction guy, I love it.

Yes but doesnt methanol require lots more fuel than compared to gasoline to reach the same octane level? You would need a much larger fuel cell im guessing. Im pretty sure the NX fuel noids are not setup to use Methonal.
Yeah....Im pretty much set on using a very high quality high octane gas like C16 or the nitrous version.
I am also just going two stages. The dry one I had previously that worked so well up to 700 rwhp and then this direct port on a window switch and maybe delay timer. I want to use the tried and true path. Nothing too fancy
