Nitrous help/advice
I have a 1994 C4 coupe that has 94K on it. The engine is in good shape, all new hoses, belts, GM tune up, all bolt ons except hi-flow cats.
I want to install a Nitrous kit on the car and wanted to get some advice on "dry" kits. I have heard they are the easiest to install.
I have been looking at the Zex kit with the computer controller. Is this the type of system that would need a plate to mount at the throttle body for injection?
I don't intend to use the system, except at the track maybe. I just want to have it on there and have the experience of installing it. I am a little worried about blowing the motor, but have read alot of myths and busts lately on the subject.
I intend to setup the kit on the low shot 50 or 75 HP.
Let me know your thoughts.

Stay away from the dry kits. Get a wet kit from nos or NX. The amount of extra installation is negligable and they are MUCH safer than the dry kits.
You should be ok if you go up to a 100hp shot. Anything over that and you are playing with fire.

Wet's the only way to go...
I use, sell and recommend wet systems myself.
Here are a couple of pics of my NS PowerStar wet system on "Snowball", my white LT1 coupe..

Ok, definetly a wet kit. Three posts in a row is enough to convince me.
I have seen a few systems that are wet and it appears that they are introducing a nitrous/fuel mix into the air intake before the throttle body. Is this correct? Nitrous from the bottle and fuel from the test port mixed and injected?
Thanks.

The debate on wet VS dry still rages on, lol.
I don't really prefer either system, but I'll play devils advocate here and throw out the pro's to the dry system.
Ease of installation. There is roughly 1/2 the components.
1/2 the components means half the wiring, which theoretically decreases the chance of a system malfunctionn by 50%.
With a wet kit, if the fuel noid sticks, you're done, the motor is history. With a dry kit, if the noid sticks, you just don't get the shot. Frustrating, but ultimately not a big deal.
The biggest con to the dry kit is adding the extra fuel through the stock injectors. If your already close to the injectors max output, installing a dry kit is playing with fire.
There's a more in depth write up on nitrous on my website if you want to check it out.

The debate wet vs. dry does still go on like which syn. oil is better.
I would go with the dry kit from Zex, I happen to have one and I did alot of reseach on it before I bought it. The total install time is suppose to be aroung 2hrs. I have not put mine on yet, there is some other mods I want to do before I put mine on. The little computer that comes with the kit hooks up to the tps sensor on your car. It only spays it at wot and if for some reason detnation begins to occur and fuel or timing is changed it cuts the juice off. I am no expert by anymeans, these other guys wet setup might kick *** but, as far as what I have learned this kit will be perfect for me and easy to install... and dont laugh at my spelling or typing Im a vette man not a computer guy

Yes only at wot, but it doesnt detect detonation, fuel, or timing for that matter, only you can stop it by taking your foot off the gas.

I'm running the 125sh ZEX. No problems so far. It's easier to use and install for a beginner. It comes with a fuel booster to increase fuel when needed and also the management unit that monitors WOT and bottle pressure. A wet kit is not safer, they both have failure points. If you plan on going bigger than a 125 shot later on then go with the wet kit.
