i was looking into buying the ZEX nitrous kit and was wondering if the dry kit or wet is better for the h22a1?

 

Combustion Cycle is made of Air/Fuel and Spark. You make more power by adding to all three, but all three have to be kept in balance. If you add Air you have to add fuel. Adding Nitrous is adding Air, so you have to add Fuel as well.

Wet-Kits: Wet-Nitrous either uses it's own supply of gas or taps a fuel line and injects gasoline via an extra injector solenoid. Wet kits allow for precise fuel metering, but can strain the fuel system if they scavange too much.

Dry-Kits: Dry kits rely on "existing" Fuel sorces to provide the extra gas. Extra gas is acomplished through either increasing the fuel pressure, or having the computer add more fuel. 10 years ago Dry kits normally meant either adding fuel pressure by injecting nitrous into the fuel-pressure regulat vaccum control line or adding it via a computer modification to the ECM. Today "dry kits" typically blow through a Mass Air Flow Meter and rely on it to detect the extra oxygen and provide more gas. Advatanges: Easy to install. Disadvatages, you're asking the fuel system to do something it wasn't designed to do and that can cause problems.

For an H22 your best/safest bet is dry system.
But wet systems will give you more power.

 

how big of a shot of nitrous is safe on a stock h22 4th gen.

55-65 shot will be fine, but you have to get colder plugs and a fpr to regulate you fuel. if you want to go 75-100 you have to buy a ignition retard system to be on the safe side

But I have seen people here do a 75-100 shot with out retarding their ignition and been fine as long as you don't spray a lot!

GO with Zex Wet Kit!!!

i know that i had planned on going with a wet just for the added safety. as for the added stress with one...just upgrade the fuel pump.

 

ive had a zex 100 shot on my car sense 2001. didnt retard the timing. i did use a one step colder plug. fuel pump is a must have for a big shot. your stock pump will b fine up to a 75 shot.
