Whoever you buy from, will tell you what you need to do.
they have kit's that are completely bolt on, with no mod's to do.
You can run a 100 shot all day long and not have to worry about a
problem. call around see what it is you really want.

Since my corvette is carburated does anything need to be changed? Autozone sells a nos system and the sales guy says he cannot answer my questions, they don't have the answers.

Who made it? (name brand) take the part # then call the manufac, and see it they can tell you. If no one can help you,
you don't need to buy from them. Don't buy any no name brand
product's. NOS could be a bad deal if not used right.

You need to change nothing, as long as you check with the
company brand name, YOU should fine tune your motor.
MSD, good wires, spark plug's, cap rotor,maybe a better air filter.
alot of little changes, to make it breath better,spark, timing.
will help it more.

Since you have a carbed vehicle, I think a wet kit would be more suited to you. I'm not an expert on carbed nitrous, but I don't think dry would work, since for a dry system to work, you need to have a device (The MAF sensor on most EFI vehicles) to sense the greater air density/more oxygen that nitrous brings to automatically add more fuel. If you used a dry kit on a carbed vehicle, you'd be forced to drive around with that extra rich mixture all the time.
Wet kits aren't that much more complicated. I installed one on my LT4. You just tap into the fuel line and have it feed the fuel solenoid that comes with the kit.

U don't want to go ultra lean when you hit the bottle
Not good!
You won't get expert advice, which you NEED at the Zone. Do you homework and starting here is a plus.
Methinks Trance said it rightly.

Trance,
long time bro! how much are you pushing? any new track times?

I am not a nitrous expert but I'll give some info that I have learned.
For starters understanding the difference between a wet and dry system is important.
A wet system injects both the nitrous and fuel and a dry system injects only nitrous.
Wet systems are setup for carbed apps. The intake manifold on carbed engines are setup for "wet" airflow. Basically meaning the air flowing through the intake is a mixture of fuel and air. The mixture has different flow characteristics than just "dry" air.
Dry systems on the other hand are designed for EFI engines in which the air is "dry". The fuel is not introduced into the airflow until the last minute. Just look at the difference between an EFI intake and a carb intake, the difference should be pretty apparent.
Dry systems are setup so that the ECM detects the changes in the air and adds fuel to keep the A/F ratio within reasonable limits.
If you use a dry system on a carb app. your going to run the engine really lean and blow it. The carb alone CANNOT compensate for the additional fuel needed. It doesn't know when and how much fuel to add. With the wet system the additional fuel required is already calculated with the nitrous and both are jetted accordingly.
People install Wet systems on EFI apps but there not designed for it. As the "wet" air flows through the intake, take for example a TPI intake, the fuel has to go around sharp turns. As it does some of the fuel condenses on the walls of the intake and mixed with oxygen from the nitrous forms a combustible mixture that under the right conditions KABOOM. You'll soon be looking at the top of your engine from the driver seat.
The new craze is direct port nitrous. Basically its a "Wet" system to work with EFI. The nitrous is bascially injected right along with the injector and not at the MAF. The nitrous nozzel is sandwhiched between the intake and the injector. This prevents the condensation of fuel against the walls as it travels through the intake reducing the chances of a nitrous backfire.

BTW you need to check what kind of pistons you have.
Cast- aren't going to last very long
Hypereutectic (sp?) - will hold 100 shot easy maybe 150 shot but thats pushing it. It will eventually give up the ghost. Also depends on how often you use it.
Forged - in this case the pistons aren't the limiting factor, the amount of nitrous you want to use is. A 150 shot is no problem but if you start going higher your going to have to take additional steps to make it work.
FWIW I am planning on doing a 175 dry shot on my Firebird

my .02, 1)go with a small power increase 1st, youcan always upgrade with different jets for the no2 spray. 2) be very sure your fuel delivery system is operating well (new filter, good fuel pump) you definitely would much rather have a too rich mix rather than too lean with no2, it will burn your pistons up very quickly.so you may want to re-jet the 2ndarys on your carb
i have had friends with no2, i never have had it so my advice is only what ive seen/heard not 1st hand experience.
good luck and keep us up to date

Thanks for all the advice... my oldest son(22) keeeps trying to get me to get a LT-1 engine an stick in my 80 corvette but i am skeptical about the fit and i don't have experience enough to do it and don't know how much the cost would be to get it done.
about the Nos , i am still gathering info and do appreciate all the info i have been given here, still contemplating this route.

Three years, myself and over $10k; swapping from Xfire. that give you any idea? A packaged system, like that from Edelbrock, may be a better approach
