FRom what i read the Zex kit seems pretty safe for a stock engine. I'm thinking about buyiing this kit for a 96 cx hb. I know that i need to get new sprak plugs, but what other mods do i need to keep the nitrous kit safe/reliable?? Right now, i just have cold air intake, new headers and cat back. Do i need new feul rails ..etc.?. P.S i was thinking about getting the 55 or 65 dry shot.

 

Out of the box, the ZEX nitrous kit is safe at the levels you are shooting for. So you are all set. However if you want to run higher shot dosages you would need a few other things to make sure you are getting enough fuel along with your NOS. Otherwise you will lean out to much and break something.

 

Colder plugs is all you need to run a 55-65-75 shot safely without sacrificing reliability. I'd highly recommend using an rpm activated window switch to avoid hitting fuel cut while spraying nitrous as this will almost surely result in a blown motor. They are between $50 and $100.

 

if you shoot 75 shot use colder fire plugs and retard 3degree.

I used a 65 shot and ran 15.1 w/an f22 (95 accord).
cold air intake, plugs,MSD plug wires and exhaust system is all I had. Its a simple kit to install and use.
