ok this is my set up

jdm b18c type r motor stock internals
intake, header,no cat, full exhaust

car has p28 ecu street tuned with CROME... for n/a though

i have a zex wet nitrous kit... with that lil computer thing it comes with

i know its supposed to evenly distribute the right amount of fuel and all that but can i use it even though my ecu was tuned and leaned out for n/a

you would need more fule. Eventhough its a wet system, unless it adds more fule its like adding a small turbo.

Science fun time! N20 breaks up about 400 degrees F releasing 1 part nitrogen, two parts oxygen. The Nitrogen goes out with the exaust, the Oxygen adds more to the air content, except it is a pure oxidiser.

Alot more air without more fule = detenation. Youll need a retune if its really leaned out. It also matters how much your squeesin! The more your suckin in, the more gas you need.

any idea if the zex kit adds more fuel or what it exactly does?

just curious if i'd be safe to do it or not

well, I dont know which kit you have but odds are the wet kit just has a 2 to 1 nozzle. N20 and Fuel into one injector, making a better distribution. Usually they do not add more fuel. I could be wrong so dont take too much of that for complete fact. Zex makes good kits, very user friendly from all I have seen.

Good luck man, lemme know about the kit when you know for sure! :thumbsup: (Gonna add some N20 soon!)
