so my y7 is burning oil at 180k so i took it apart and put in some eagles with some wiseco pistons, now plz don't say just go turbo or blah blah, i want some input on a nitrous setup since i have forged internals now i might want to push it to 100 or 125 shot, but i'm starting out with nitrous so im gonna follow the usual advice of starting low, my goals are really not that high just 200whp-220whp with the shot, the engine is pretty much stock other than the usual cheap i/h/e and the new rods/pistons, i do have a chipped ecu going in and willing to get a wideband if its recommended for the setup

so any input on what nitrous kit to buy or any links for any websites that sell kits or components is great

for the moment i don't want to go with a direct port setup i want to learn first and go with the single nozzle wet or maybe dry if its really worth it...

Direct port dry with tuning for fuel and ignition would be best.

A single nozzle wet setup at 100 shot is asking for trouble. Lots of people have gotten away with it and even more have melted pistons.

Your engine is EFI, that means that the intake manifold was not designed to have fuel in it, only air. By spraying fuel into it with a shitty nozzle you are almost guaranteed to not have equal fuel distribution between cylinders and even worse fuel drop-out into the plenum.

This, I have had this kit on my car for a while with no issues, in fact I just got their window switch installed. Zex= best nitrous products

I disagree with that as well. Zex is better than NOS, but thats not saying much.
When it comes to the american kit makers NX is the best, but they are not immune to idiocy either. They just have decent solenoids (lightning) and nozzles (shark/SHO).

WON makes the best kits out there if you ahve the coin.

I known people in the past that have had NX they are a good company and make good products as well. I just know that zex stands behind their products and I've never had an issue and I had my kit for years. I agree with you on that. I would would not use a NOS product.

ive read somewhere that the nx nozzles are better for atomization than any other, i need to order a kit without a bottle because of shipping charges, i can buy the bottle locally, i seem to be having trouble finding the zex kit for the civic application i remember finding a part number for it like a year ago now i can't find anything.. i saw the proton kit on the NX web site with no bottle for $335

Nitrous Express Next Generation Nitrous Oxide Systems PROTON SERIES NITROUS SYSTEM WITHOUT BOTTLE

has the piranha nozzle and the boxed selenoids, some people say these boxed selenoids are not the best...

i plan on getting..

1. kit no bottle
2. bottle
3. tps switch
4. window switch

maybe ill get
- wideband
- lean condition switch (it needs the wideband i think)

going for 50 shot learn how it all works then go to the 75 shot, then as fulltilt said ill just go with the DP dry and tune it

NX makes the best nozzles when it comes to the american makers. I havent seen back to back testing but I suspect that the WON crossfire nozzle would outperform the NX stuff.

Nozzle Shootout

The difference between a bad nozzle (NOS) and a good nozzle (NX). Same jetting, same car, back to back testing:


Of course the best performing would be dry with the injectors enriching fuel...

!!

If you are running anything over 50hp shot go with a wet kit...hell any hp shot go with the wet kit much safer than dry as it adds fuel to the spray.
just because you can doesn't mean you should. I believe wet kits were intiially designed for carbed engines because the carb has fuel added to it as well as air. fuel doesnt go in an intake! air does!!!

yep because all he has to do now is to simply click my nitrous install in my sig for guidance lol

.................. i believe you need to do alot of digging............ but i will stop posting and sit back and watch how well someone knows there stuff or how to use the search function

how about port injection on the underside of each IM runner right underneath the injector?
Thats what im working on now i can get you pics on what i did if you want

the only problem ive had with (nos) was the solenoids going bad on me over time. and i would say if you had money yes NX is the way to go. and overall i like the NX product line over zex.

what is the usual spot to tap for fuel? i don't want to cut the rubber hose, i guess getting a fuel rail would be super clean... i might want to try and hide the system on the engine bay

Yep thats pretty common. NOS solenoids are basically a re-purposed solenoid that is not rated for the high pressures of liquid nitrous. To fix this they make the seat out of a soft material in hopes of making it seal under the pressure, but over time the seat will deform and it will start leaking, especially if youre pulsing them.
If you want a progressive setup you reeeeeally need good solenoids.

At the same time, dont fall for the gimmicks. When NX first started they made a big deal about their solenoids being made of stainless, saying that aluminum solenoids were inferior. Now, years later, their best solenoids are fully aluminum. Edelbrock says the same thing today with their stainless solenoids.

This is what youre really looking for in a solenoid, a good path of nitrous flow, with minimum sharp corners and minumum room for expansion (these things cause the liquid nitrous to turn into a gas).

Generic solenoid (found in most kits:


NX big solenoid (what I used on my last setup):


WON solenoid (what ill use on my next nitrous setup):

anyone know which tuning software has integrated nitrous control? crome? ectune? neptune? i might just skip the window switch and all that for the actual software and just tune it and apply the nitrous control features..

i made this thread to get input so i can do it right the first time, only a direct port kit does not come already done for the stock manifold it requires work, and as i understand it you need to know what you are doing when bending the plumbing for the nozzles, so as i said i'm am new to nitrous and the best way i have found to start is a wet single fogger kit and start at a low shot and work my way up, anyway i still have some unanswered questions

can ectune or neptune control the nitrous?

what is so wrong with a wet direct port that you guys recommend the dp dry?
