What is safe for nitrous on a H22A4
Hi- I have a prelude with H22A4. What do i need to do to run nos safely. Fuel upgrades, ignition, i dont want to run more than 75 shot. And what is teh best setup to use on these motors, wet, dry, or direct port and what is the difference between all these. I have searched but only found general answers, I need specifics. Thanks so much, I am new to NITROUS

Re: What is safe for nitrous on a H22A4 (hatch4raceb16)
Are you refering to what is a safe ammount to squeeze? If so...on my relatively stock motor I did a 60 shot single fogger. I had no problems. My buddy with a 4th gen lude as well squeezed an 80 shot direct port safely on his stock motor...hope this helps

Re: What is safe for nitrous on a H22A4 (emoBB1)
for a 75 shot i would run a single fogger wet kit.
a clutch that can handle it will also be needed. that 75 shot will eat your clutch.
get yourself a new ignition system like the MSD Digital SCI + so that it will retard the timing only when you spray.
get a fuel pressure regulator and maybe a fuel rail. your stock pump should be just fine.
I would also reccommend getting an electronic nitrous pressure gauge for inside the car, feul pressure gauge and air/fuel ratio mix.
according to NX you should retard timing one degree per 50 shot of power (using their system of course). so safetly i would retard yours two degrees when spraying.
these are just my suggestions, personally i saw what you need to do for a 75 shot, said screw it and got a Direct port kit with 100 shot jets. only differance really is with a 100 shot you should upgrade your fuel pump.
direct port is safer then a single fogger kit. single fogger kits do not evenly spread the nitrous to each cylinder whereas a direct port kit does evenly distribute the nitrous.
now for anything 75 shot and under you are safe to go with a single fogger kit. i just like the idea of the DP kits better.

Re: What is safe for nitrous on a H22A4 (shakes)
thanks shakes, but can u explain to me what a direct port system is and what a single fogger kit is? Also what is the diff between wet and dry. Thanks so much.

Re: What is safe for nitrous on a H22A4 (hatch4raceb16)
I personally would either recommend the new Zex wet kit (direct port) or the NX kit and run no more than 55-65 shot without retarding your timing. I say this because both kits offer ease of installation and i know the Zex kit adjusts your fuel pressure in regards to the jet that you have installed (i.e. 55 hp jet e.t.c.). I personally am running the Zex dry kit with the remote opener and 55 shot and two step colder zex plugs. It really does make a nice difference in acceleration and as long as you don't abuse it, you motor will stay healthy for a long time (checking for detonation on plugs e.t.c.) I've personally have seen too many NOS installations go wrong because of bad installs e.t.c. If you go with the NOS brand, make sure to get a competent nitrous installer to put it in for you unless you have experience with nitrous installs yourself. I personally installed my Zex system myself in stealth mode and not even the Honda mechanics I take the car to know it's there

Single fogger
A single fogger system has one nitrous nozzle. The solenoid goes directly to the one nozzle located in the intake piping. Usually it is placed apx 6 inches from the throttle body. When you spray (either by button or WOT (wide open throttle) the nitrous will flow down the intake tubing into the intake manifold.
The problem with this is that the force of the N2O moving will generally either blow past number 1 cylinder or mostly go into number one cylinder. it depends on the location of the nozzle from the TB.
The reason that this isn’t too big of a deal for 75 and under shots is because you are not dealing with that much juice. So even though it isn't all evenly spread it should not affect the engine or performance greatly.
Single fogger kits can be acquired in either WET or DRY kits. A dry kit sprays only N2O.
A wet kit has a fuel line that is attached to another solenoid and is activated at the same time as the N2O noid. The nozzle then mixes the N2O and Fuel as it sprays it into the intake tubing.
This is considered safer because you will have less of a chance to lean out your engine.
direct port system:
A direct port system is attached directly to the intake manifold.
You intake manifold has four runners. Runners are what take the air from the main part of the mani to each cylinder.
On a direct port kit you will have the one fuel and one N2O noids hooked up to copper or steel tubing going to each runner. Each runner will have their own nozzle.
The reason that this is considered the safest way to spray is because each runner will have its own nozzle. The nitrous and fuel will always be evenly spread out.
So on my system for instance I will be running a 100 shot NX system. So essentially I will be putting a 25 shot into each intake runner.
Whereas a single fogger kit will throw the entire shot at the TB and hope it spreads as evenly as possible.
hope this didnt confuse you. and laughinxxx please correct me if i am incorrect on any of this. you are the expert, i am still learning a tad.

Good details. I myself am running the zex dry kit. I actually located the nozzle 10" from the throttle body to allow the nitrous/incoming air time to mix more evenly. Alot of problems with installs come from actually placing the nozzle way too close to the ITB (less than 6").
