Yeah, I've got the NX Import EFI Kit and the GenX2 Upgrade.
I'm actually 2nd guessing whether or not I should try the 100 shot of NX as it's going to be more than what other have been running (100 shot of NOS).

i'm running a pieced together NOS kit. (solenoids and bottle) the rest i had to put together myself. i also dont have the jets that came with the kit, i replaced them with my own.
races are tonight....
would i find any gains/benefits from running open header??
might watch your A/F ratio if you run open header. you might be running a lot leaner.

What? I think you mean your WB/O2 sensor will read leaner. Which is not a safe bet to do. You'll want to keep a very accurate monitor on that. IMO an open header isn't worth the risk of a bad O2 reading. Since I got my Greddy e-manage set up and sold my nitrious in favor for boost I'm kicking myself because I could have gotten so much more out of the Juice by retarding the timing and playing with the fuel mixture.
*Oh hey if you don't have a wide band O2 in there, opening the header to will let air in at idle and throw a CEL for and inproper )2 sensor, then the car will run like crap.
Whoa, yikes hey, how far back off the Throttle body is your jet nozzle? The poping is probably detonation! Try moving your nozzle back off the throttle body down near the intake box or where it was. Also you'll eff up your engine if you don't run colder plugs. I tell you what, if you can't find any or your short on change or something THINK I still have my set rolling around in my goodies pile, I'll send them to you! I also have a set of bigger injectors too, but those I can't let go as a freebie.
If your getting a poping noise its because your plugs aren't doing their job getting heat out of the combustion chamber. The limiting factors on nitrous isn't injectors or sturdy pistons. Its how well you can control the heat. What is happening is the combustion chamber is so hot that even when the plug isn't sparking your getting ignition. If you keep running it like that it will burn the next flamable thing in the combustion chamber---YOUR RINGS or worse it'll blow a hole in the piston. You can get a vauge idea of whats going on by monitoring you A/F ratio and if the damage is already done and its been run like this for a while you should have a look at your car while it Idles.
Are you getting alot of smoke? If you are it may be blow by. which cars with high miles tend to get anyway but this is probably a result of lean conditions.
In order to zero in on the problem a compression and leak-down test should identify the problem. You compression numbers should be ok, it will be the leak down that will tell you how well the rings are doing.
Here's your best bet. If you need to, take the car to the dealership and have them perform the compression and leak-down test for you. This will let you know what's going on inside. Then you need to invest in some injectors and plugs to ice things down in there. This will insure that your baby keeps kicking.
figure on $50 for plugs and anywhere from $80-300 on injectors (depending on if you go the cheap route) and you'll want to get an A/F ratio monitor I use the NGK AFX which is about the cheapest one out there right now. Also to make things easier you'll want to pick up a piggy back unit like Greddy or Hondata to take the guess work our of your fuel management. A used greddy e-manage can be had realitively cheaply off of ebay these days. If you decided to go the cheap route the you'll be messing with a FPR to try to get your A/F reading in the sweet spot under load. Another benifit to the emanage route is you'll be able to adjust your timing too not that its necessary for anything less than a 50 shot.
I went the Greddy route because the Greddy was cheap and it provided a stepping stone for me into forced induction. This way when I started piecing together a turbo kit I already had a decent engine management system and a way to monitor my A/F ratio with the AFX. Granted the Greddy can't do as much as the Hondata but its all in what you want to spend. How fast you go is directly proportional to the size of your wallet.
From my experience I had my Nitrous for roughly a year and went through 24 bottles. I'll tell you that I have blow by because of my ignorance when I got into the juice but I was wise enough to use the internet like you to solve my problems and make my engine last. I'm now working on my turbo kit as well as being in the middle of a 5 speed conversion. I know that the blow by that i have now will be much worse when I put the turbo on. When it finnally gets to a point where the engine is dead it will be my stepping stone to sleeving the block and getting low compression pistons and bumping the boost. Its up to you with what you want to do. If you have any more questions I'll give you a hand because I've been there before.
solenoids, nozzle, and purge. gold fitting by the wiper arm bolt is where the purge exits (shoots parallel with the windshield)
insurance for nitrous use: msd window switch and msd digital 6+ (also pictured is my brand new civic sized battery)
bottle, heater, and blanket
switches: (from left to right: 2-step "On" switch, nitrous arm, bottle heater, and purge)
