Do you know if there will be any timing-retards coming out?
Yes, we have to retard the timing when we use nitrous. The reason is because the oxygen becomes more dense, and that cause the A/F mix to burn quicker. That cause the peak cylinder pressure to happen alot closer to TDC. Because of that, not all energy created by the combustion is used to power the piston, but instead is it transfered to the rotating assembly, possible damaging it over time. So, to stop all of that from happining, you need to retard you timeing roughly 2-1/2 degrees for every 75 hp added.

I personally was liking the Zex Kit, and was checking out different things about it etc. But at HPP (My Tuner), they really prefer Nitrous Express (N/X). I just found out that the main N/X place is located in Wichita Falls, Texas. Which is actually only 2 hours away from me. So, I decided to look into them, I've heard great things from them, and have been recommended to check them out if I go Nitrous. You spoke of Dynotune? I'm not to familiar with them. Though all in all, you seem very knowledgeable about Nitrous, so what do you think about the N/X Kits, I mean the solenoids on their's seem soooo much reassuring than other kits like Zex, NOS, etc. I appreciate your info man, it's really helped me out.
Thought I might throw this in there. I haven't heard much follow-up on this but there might be a way to run a street tune and N2O at the same time

This is a question that goes back and forth between MANY people. First of all, I would NOT recommend the Dynotune kit. I had 3 solenoids fail on me before I finally gave up, so its not a well built kit. I was actually going to update the FAQ today.
With Nitrous, it truely is, you get what you pay for. Don't look for cheap kits. Now, with that being said, N/X and Zex are both very good kits. The only real difference between them is the way the solenoids are. The Zex kit contains a box with the solenoids, so nothing is really exposed. Its a MUCH cleaner looking kit, and intalls MUCH quicker (you don't need to pay your tuner to install it, you can do it yourself). Also, the good thing about the Zex kit is the integrated TPS. This way your activation is always at WOT, I don't think the N/X kit comes with that.
Overall, I would suggest the ZEX kit, especially if your are doing the install on your own. However, seeing as there is no major difference, if your installer likes working from N/X, then it probably would be smarted to get that (since the know it better).
Let me know if you have any more questions!

But me....questions....what are you talking about..LoL. Well here it goes.
I'm thinking either Zex or N/X. One of the two. Now I do know it's gonna be a while before I do this, but it's what I think will truly best suit my performance needs for my car.
First off, before I even THINK of going Nitrous, I'ma finish up my FULL N/A Engine. That means even the usless BBK TB, Steeda Spacer, but the not soo useless Mezeire Water Pump, Battery Relocation w/new Battery, Cams ( Comp F4.6 3V Modular XE261H-15.5 Cam Set) etc. Of course ARH 1-3/4" LT''s w/ X Pipe, maybe Exhaust cutouts...I dunno yet. PH Aluminum DS, PI Torque Converter (3000-3200 Stall), Fuel Pumps (GT40), Fuel Rails (Metco), Injectors. Full Suspension, Brakes, Wheels/Tires, and thats about it. . I'm really sorry man, I just kinda wanted you to get a picture of everything.
Now here comes the Nitrous....
Now like I said, either N/X or Zex. So lets see what I need first.
- Nitrous Kit - Bottle Pressure Gauge - Bottle Heater - Purge Kit - Blowdown Kit - Window Switch (For RPM's) - Remote Bottle Opener (Extra) - HTO Plugs - Extra Bottle w/ Gauge, Heater, Blowdown, etc. (Extras as well) If expenses permit of course.
For me I wanna go ahead and throw on some gauges for precaution, as well as safety measures.
Well, as you can tell I've done quite a bit of research. But I'm not fully knowledgeable on the matter. So when it comes down to it, after you seeing what I have, and am planing on doing.
Which kit? Am I missing anything? What about that third gauge? What TCS Window Switch should I go with?
Now, the Zex kit is around $550, and you can get the Racer Tuner Kit for $391.21 which includes bottle heater, blowdown kit, and purge kit, o yeah and the bottle gauge. That leaves me with the TCS Switch, and Remote Bottle Opener, then of course my extra stuff. So right now the Zex kit is sounding pretty sweet. Though, do I have to use their brand Window Switch? It's soooo expensive.
Now I'ma look into N/X a little bit more, but since the Zex it soo easy to install, might get it of course. Though N/X is very tempting since they are right by me.
Sorry if I went on too much, and elaborated in the subject. I'm just trying to find out all the info possible on this. Thanks man

First off, thats a very impressive list of modifications. Looks like you know what you want. So let me ask you, why Nitrous? I'm pretty good with nitrous, but if your serious about power, a supercharger/turbo would be a much better way to go, and not only that, it would end up costing you less in the long run. However, if you want to do nitrous, here is what I suggest for your setup.
Zex Kit - $550 "Racer Kit" Bottle Heater. Purge Kit, Bottle Pressure Gauge, Blowdown Tube - $400 Bottle Heaters doesn't have to be from Zex. In fact, there are some cheaper ones out there that regulate the temperature automatically, which is easier. Remote Opener - $300 TCS/RPM Switch - $150 I know its expensive, but remember, YGWYPF. Go with the Zex, better then having a different one fail on you. HT0 Plugs - $100 FUEL PRESSURE SAFETY SWITCH - $40 THIS IS VERY IMPORTANT (hence the caps). You did not have this on your list. This is a switch that gets tapped into the fuel lines, and will save your engine if the fuel pump dies. This is to prevent grossly lean situations which WILL cause detonation. Very good safety device for the money. YOU NEED THIS! For a Dual Bottle Setup: Extra Bottle Plus Joints - $260 Extra Bottle Heater - $150 Extra Remote Opener - $300
Total for single bottle: $1450 Total for dual bottle: $2160 (Thats without the tune and the pizza/beer for the install )
For your gauges, Gauge 1 should be your Fuel Pressue Gauge (this is the most important one). Gauge 2 should be a good Wideband gauge (AEM is a good brand). Don't waste your money on narrow band stuff Gauge 3 is up to you. Its a close call between nitrous pressure and oil pressure. You should know about nitrous pressure, especially by feel on the car (you will know when your running low), oil pressure is a little harder to tell.
For your switchs, I would recommend going in order... Bottle Opener Zex Arm Zex Purge Line Lock
I know their window switch is expensive, but its built to work with their kit, and it would be a good idea not to mix and match parts. The only parts you don't have to buy from them is the FPSS and the stuff in the "Racer kit" (although I would get a purge solenoid from them so that the colors on the kits match.)
Even though N/X is close to you, it would be cheaper to get their stuff from the net. Overall, for what your looking for, I think Zex is a good solution.
I think I answered all of your questions, if I missed something, let me know.

Yes, you answered it all perfectly, could ya give me some sites on the Fuel Pressure Safety Switch though.
Now, I honestly want 325+ through my AUTO w/4.10's and Torque Converter I might add. I do not want a TC or SC, as I just want the "Extra" Power when wanted, not all the time. Another thing is that if I ever threw on a KB S/C or PH Turbo (My choices) I would want a FULLY BUILT MOTOR TO HANDLE IT, and a coupe...LoL.
I know that by the end of summer I'll have everything done except the Nitrous. So it's still a ways away. I'm just very cautious over everything I do to my car, and I tend to ask A LOT of questions.
BTW, I love your sig. I actually have Excel Spreadsheets for all my parts, as well as "Stages" that you put as "Phases". I've finished up my basics and a little Exterior. I really apprexiate it manm thanks..

Haha, I have the same thing. Excel Spreadsheets, with "Phases", and everything. I have every part I want to buy, type and brand, and where to get it, plus a projected price. So much to go...
Let me know if you have any other questions. If your ever in San Antonio, you can buy me lunch.

Anyone know if anyone has gotten a Nitrous kit that's a "hidden" kit, like the NOS "Sneeky Pete" kit? I've looked at that one, but that kit will only work with carbureted engines, so it's not gonna fly with my '07...I want to have something that's not visible when you first look, and doesn't require a huge bottle that's going to take up enormous amounts of trunk space. And I want something that I'd LIKE to think I could reverse, without having to buy a brand new intake manifold, because I had to drill holes or anything like that...
Maybe I just am wishing & hoping for something that doesn't really exist...

It's a very sneaky kit actually, nothing like the NOS kit your talking of though. But the bottle on the Zex Kit will be in the trunk, but that could be customized to be placed in your spare tire/jack area??? Check it out man. Look at different pics of the Zex kit.....it's very smooth and clean under the hood.

If your looking for a small kit, (i wouldn't reccomend it because you'd have to get the bottle filled every single time you run), look at the Venom VCN-500 Recluse kit. I think thats the name. It can easily be hidden, and has a very small bottle that can be mounted almost anywhere.
As for drilling holes in your intake manifold, you don't have to do that, you drill one in the intake it's self. If you want to take it off, its nothing a little duct tape couldn't fix.
