I have an 03 gt a cai and full exhuast. I ordered a Zex 82023 wet kit. My main question is timing. I did some searches but didnt see anything specific. The Zex site states at a 75 shot can be run on 0 deg. But, at 100 shot should be at 2 neg. I dont have the ability to retard the timing, and i was wanting to run at 100 shot. on a 1-10 scale 10 being detonation how risky would it be to run 100 shot at 0 deg timing w/ colder plugs?

Ive been looking localy for Colder plugs but the local national auto stores dont seem to carry any. been to about 5 stores with no luck. Any sugestions where to look?

Without taking it to a shop is there any way i can check the A/F ratio? I did a search and pretty much seen that the gauges I could install wouldnt be very reliable. Without spending like $600 on a quality set up.

Been researching and tryn to gather information for the better part of a year on nitrous and now that Im almost ready to install I just want to make sure i got all my bases covered. Never owned a nitrous equipped vehicle (if that isnt obvious) and would love any tips and or pointers on installing the wet kit.

I dont have alot of experiance working on cars but with haynes and stangnet Im pretty sure i can do most my installs tools permitting. Thanks in advance for the info and patiance with yet another nitrous thread.
 
I dont know what all that particular ZEX kit has, but for a good safe n2o setup youll need:

bottle/lines/solenoids etc basic kit
master arming switch
window switch
WOT switch
FPS switch
bottle heater
pressure gauge

NX fuel block (to reduce lean spike, really good idea)

a purge kit is nice

autolite 103 plugs (1 step colder & copper, any autoparts store has these. you must run copper plugs.)

a way to adjust timing (predator/chip/steeda adjuster). you might be able to get away with stock timing for a while, maybe never have problems, but if you want to be safe you NEED to retard timing 1* per 50hp.

DYNO TIME. Do NOT avoid this. The $60 AF gauges are narrowband and useless for tuning, you at least need a wideband commander setup ($500) if you want to skip dyno time. Its imperative that you strap down to the dyno and see your AF ratio unless you just dont care about what happens to the motor.
 
You can keep the factory timing but you'll have to run premium gas. I ran for about 2 years with a NX 150 wet shot on factory timing BUT I only used the 150 at the track (ran premium with a bottle of octane booster) ran the 100 shot on the street with nothing but premium in the tank(91 octane).
 
I was tryn to lock down which spark plug was for the 03 gt and could not figure out whether NGK BP7EFS (PN-3526) or NGK BR7EF (PN-3346) was for my year. Also the auto store could not find the autolite AR94. If any one has any info on which NGK plug or what the autolite plug part number is i would greatly appreciate the info.

thanks.

How do you wire up a window switch to a 99+ 4.6? I just install my NO2 kit this weekend but I couldn't figure out how to wire in a window switch I got from my friend so I just used the WOT switch. I would really like to use the window switch, any help someone could provide would be great! Sorry to hijack the thread if I've done that...but I bet the original writer will need this help too.
Thanks!

It depends what brand of window switch you have. Some models require a tach adapter to be able to read the 99+ GT's digital tach signal (COP system).
