Well, because I work for a mod shop, my pricing is pretty good. I can buy the ZEX sytem with remote bottle opener, bottle warmer, and purge kit for $868. The NX system is considerably more expensive. The same system would run me $1156. NX makes the GENX-2 kit which is a nice addition to their system and it would run me $374. The GENX-2 is palm computer programmable, and that's cool, but I don't have a palm PC. I've attemped to contact Venom to see if they have a VCN-2000 system for the 8, but haven't been able to talk to anyone there yet. Assuming they had a system for the 8, it would run me about $1400.
It would be nice if Venom had one because itties in to the O2 sensor to moniter air/fuel and it cuts nitrous if you're running too lean. The Zex and the NX (as far as I know) don't have that option at this point. Still researching...

Great!!
If you wouldn't mind, please take pictures!?
How big of a shot do you think you'll try out? Just wondering, since you arent really concerned about destruction.. Don't forget to start small and increase gradually.. AFTER checking your plugs for a lean condition.. If you're going to do higher shots, you should probably monitor the exhauhst gases..
What other internals upgrades are you looking at?

OK, after doing some thinking, I'm considering just pulling out my Stage 1, and doing a bottle. I'll explain why. My initial assessment of the Stage 1 was good, but after driving the car more the last couple of weeks (better weather), I've decided that I don't like the way the car runs with it. I made some runs and opened it up a few times. I've not only experienced the 4500 rpm dip (which kinda sucks), but I've experienced a "hesitiations" in the higher rpm range when in 3rd or 4th gears. These hestitations almost feel like the car is just "stuck" (for lack of better terms). I literally have to hold the throttle down and just kinda wait for it to "go" again.
I'm not all that well versed when it comes to mods such as the Stage 1, but something just doesn't feel right with it. The car almost seems slower to me a lower rpm ranges (and no, it's not because it's faster at higher ranges). I spoke to CZ just days ago, and expressed my "conent" with the unit, but I'm really a bit concerned and not quite pleased with the car's performance after further runs with it since that conversation.
I'm aware of the ECU reflash "situation" and my car hasn't had it, so that's not the issue. One of my main reservations about doing nitrous, was the fact that I was running the Stage 1, and I was afraid of "leaning out" and having the motor take a dump. Like I said, I may pull the Stage 1, and possibly petition CZ to let me return it. And then hopefully do a NX kit and see better results. I don't need the "extra" hp for most of my daily driving, so the nitrous kit makes sense for me. I get the extra hp only when it's needed and called upon.
I'd like to state that this isn't a "knock" on the Stage 1. I just don't think it fits into the plan I have for this car. The plan I have really isn't a complicated one, I'll just run pretty much "stock" unless I hit the 55 shot when I need to, which will probably be very little.

Well if you are one of the few who can afford to blow their engine out of warranty and not care... you'll not hear any naysaying from me. Once that (blowing your engine) isn't a concern to you, I'm all for trying whatever you will and sharing the results of your experiment with the rest of us.
Good luck and keep us posted.

Here's the thing; I followed another conversation between Chuck Huang and numerous others on this site. It seems that there is an expectation of altruism and compelled "sharing" by the majority who post here. My personal position is more along the lines of that which Chuck has. If I am going to test the limits of the Renesis, I am going to find a way to recoup my losses in one, or more, ways. If that makes me "selfish", so be it. Once I get my 8 to the levels I have in mind I will first set my sights on the local musclecar drivers. Being from Detroit, I have plenty of opportunity to score some wins for the import tuning community. Many years ago I used to hustle the streets as portrayed in "The Fast and the Furious". Although many people consider that movie a farce, I can tell you that is exactly how the game was run back in the '80s in Detroit. Lots of money changed hands around here and I was one of the recipients. My point is this: I will share stories regarding the general information as to the stress limits of the Renesis. How I found that out and how I acheived certain horsepower levels will be up to my own discretion. I am sorry if that makes me a jerk but I am looking for a career change and the RX-8 seems a great opportunity to do just that. If all goes well, perhaps I can offer the RX-8 community the parts necessary to go faster, handle better, and get better traction. That way, I can come under the same scrutiny of Rotary Extreme and every other maverick around here. Of course, all this is said with a smile and positive disposition.
Sincerely,
Charles

I was working on my custom speaker box for Mr. Wigggles RX-8 last week and noticed something that no one else has mentioned on these cars. It may make some things interesting to those who plan to use nitrous but not use a nitrous kit such as the Zex or a Venom system. Due to the location of the driveshaft in relation to the gas tank, the tank is very high in the center. The tank goes down around either side of the driveshaft. There is no connector below the driveshaft so that fuel may move between each side. The top area of the tank above the driveshaft is still common so it is only a single tank. As a result of this shape there are 2 fuel pumps. One on each side of the hump. It is really interesting since the access to each pump is under each respective rear seat. Anyone wanting to ever upgrade the fuel system someday to a complete standalone system with a new fuel system will have some work ahead of them. Just thought some of you might want to know this.

I'm sending back my Stage 1 today for the 1.1 upgrade. I'll see how it goes afterwords. But with the timing adjustments, I surely can't run the Stage 1.1 simultaneously with nitrous.

You could potentially buy the programming cable, software, and monitoring sensors to adjust the fuel/timing yourself with 1.1.
