Write up from another forum - This should answer a lot of your questions.
Here is what I used:
ZEX Universal Nitrous kit + all Zex Accessories
Remote Bottle Opener
Blowdown Tube
Bottle Heater
Purge Kit
Jetted currently for a 75hp shot.
I also bypassed the ZEX Throttle Position Switch and did a pedal switch for
WOT positioning.
Well after the hell I went through to get it installed... I finally got to try it out on my way home from CA today!
It isn't the throw you back in your seat kind of upgrade I was hoping it would be but I can definately tell the difference. I tried it a few times on the highway. Once from 80, 70, and 90. The 80 to 100 run that used to take forever comes a lot faster now. The 2gear downshift at 70 is even more awesome.
I also tried it from 30mph to catch the downshift back to first. Wow.
As soon as I floor it and the nitrous hits the engine, the exhaust just freakin screams and you can hear it injecting under the hood.
I haven't tried it off the line yet.
The longest I held it down for was about 5 seconds. I am waiting on my colder plugs before I run it longer. Even though it sounded great and I didn't hear any knocking or pinging, I still want those colder plugs before I push it.
Now the big question. Was it worth it? As of right now, HELL YEAH. But we will truely see, when I hit the track!
