Venom, Zex, and NOS are using different kind of system.
There all do the same trick, supply more oxygen to your engine by using nitrous.
Nitrous = N2 + O , which is 33 % compare to 22 % in atmosphere..( 22 ? not sure

)
Correct use of nitrous wounldn't do any harm to your engine.
Before using nitrous, you have to:
1. Get a Walbro 190 fuel pump, if you using higher than 45 shot.
2. DO NOT use plantinum spark plugs, only non-plantinum
3. Gap your spark plug to 0.35, cooler plugs will help -> I choose probe spaks plug: NGK BK6ER11
4. Do a compression check before getting Nitrous. Nitrous will kill your engine faster if you have engine problem, example: broken piston ring
5. Stock Clutch is sucks. Prepare to change your clutch anytime soon if you using nitrous.
6. Make sure your fuel side (like Mike said) is working great. Try to get your fuel system clean by using "Fuel System Cleaner". Personally recommend Chevron, Techron. Black bottle, selling 5.99 in Walmart
7. Only pour high octane gasoline. 93+ is recommended. Octane booster is NOT a choice.
8. Always try to use smaller shot first ( smaller jet sets).. and go up all the way to max 75. Our car is not safe for higher than 75 shots
9. DO YOUR HOMEWORK !! I study nitrous for 5 weeks before using it. You should too.
