Hi,
I have 2 questions, I have a 2001 Prelude base h22 and have been doing upgrades to it so that eventually i can run nitrous. im familiar with it since i had it on my gsr before is was stolen. the kit i have always look at was the n.o.s/holley plate kit that is available for the gsr and my first question is if this kit will be compatible with the h22- i have heard that it might be possible and fit.
My second question is recently the NX efi stage 1 system has caught my eye but im not familiar with its reliable or difficulty of installation. does anyhere here reccomend Nitrous Express systems??? thanks in advance

 

The only system that can use the plate kit is the GSR because of the manifold design. As for your second question, I personally recommend the Zex kits.

 

i love the NX efi kits, ive installed a few, and theyre really easy. i think 3 of my friends run them, and i have a brand new one for sale for 400. shipped.

 

dont get the h22 plate kit...its junk. go w/ a direct port setup or the single fogger

 

after a little more research im leaning towards getting the single fogger wet (nitrous/fuel) kit. direct port fogger seems like i might run into some problems on fairly stock internals with just upgraded fuel/ignition upgrades and tunning. i know n.o.s. has one available but im not sure if the nx stage 1 kit is a wet system, does anyone know how much of a problem i would have with puddling ?? sorry for all the questions but just trying to do decide right.

 

Don't use a wet single fogger. The Honda intake manifold was designed to flow air not fuel. Wet single foggers are well known for fuel puddling and nitrous backfire. Not a good thing.

Go with a Zex dry kit, or if you are set on a wet kit, get a NX or NOS direct port system.

 

with the NX EFI system ive NEVER heard of acomplaints or a problem

Injecting fuel before the intake manifold on a Honda is just dangerous. The design was that for a MPFI engine, meaning it only needed to flow air efficiently not fuel. Injecting fuel into a manifold of this design is just asking for uneven distribution and puddling of fuel. In other words, lean conditions and detonation.

 

ok well in the many instances ive been involved with there has NEVER been a problem, like i said

 

what about if you change up the manifold to say a skunk 2 on a gsr and NX tech says no problem useing the wet kit with a single noxxal they seen 150+hp on a single nozzal with there own eyes with a built bottome end and they had no problems

I guess it might work. Not my preference though, I feel safer with no fuel in my manifold. I prefer it to come in through the injectors, or direct port.

 

but if you think about it the fuel is going to be vaporized becouse how the nozzal works and the n2o will pull the fuel out of the nozzal along with the fuel pressure and it is going to be a mist of fuel if it was a steam it will puddle and if it was a stream it wouldnt burn right

and the skunk 2 or the itr mani looks like it will flow a wet kit better then the stock gsr mani and with that there is gojng to be a less chance of anything bad happening

Talk to Mista Bone about the NX wet single foggers, he has known them to fail a couple of times and backfire into the manifold, he originally warned me when I was trying to choose a nitrous kit. It probably will work fine for most people's applications, I just wouldn't take the risk. I also am not to familiar with the Skunk 2 manifold, but more than likely it would flow better than stock for a wet kit.

 

then go with the nxl kit


plugs right into your injectors
more money but similar to a direct port but with 1 hour install

 

the GSR plate system is what i used last year, worked well but not the best like a DP system tapped into the IM runners. from what i remember reading awhile back, Holley/NOS was working on an H22A IM plate system similar to the GSR IM plate system. from what i know the H22A uses basically the same style dual-stage IM as the B18C1, but different dimensions.

the best system to use is a Direct Port and tap into the IM, either an ITR or Skunk2 IM. then you can run 75 shot on a stock motor, but increase the injection size if you built the motor or feel like you want more power with the internally stock motor. also the distribution is even, and you have the fuel and N2O mixed together so the injectors don't have to do any extra work. just use a 255 fuel pump. i may take a bit longer to bend the lines and tap the IM but i feel it's worth it over both the Dry and Wet systems that inject before the TB.

 

bottlefedb18c1, don't think I'm trying to bash the NX kits. Out of their kits though I would just rather have their direct port like this one.


If single fogger, my vote goes to a ZEX dry system.

 

so basicaly if i want to do this with my single nozzal i have to get the 2 manifolds metal lins and 4 parana nozzals

 

You would need four nozzles, a distribution block, lines, and jettings.

thats a thing of beauty.

do you have a picture of it installed, want to see how much of the line work you can see, since it looks to be more of a sleeper install.

 

fyi- that direct port setup you guys are lookin at is mine and is for sale...the manifold is for a gsr. this kit has never been used, i went with the nxl at the last minute....im for details...

Yeah I was about to tell them it wasn't mine. Sorry for using your picture, I saw it in another post and liked it.
