I'm getting a NOS kit here in the next 2 weeks and the guy I'm getting it thru says I can run it direct port with my carb setup.Is it possible to use it so the nitrous sprays thru the ACV block off plate if I drill and tap it?Thats the only way I can see it being a direct port setup.Then it would distribute NOS thru the entire lower intake manifold with the fuel mixture on its way into the engine.Any ideas.I need to pound some hondas this summer real good too.Cocky "H' lovers. :rant:

If it helps I plan on running a 35 shot till I get a spare engine.Then I goto a 50 shot. :twisted: Teach the those "B series" boys a rotor shape can of whoop ass. :twisted:

how about where the primary injectors used to be?

I don't think the sprayer would fit in there properly.Thats why I figure thru the ACV block off plate.Just drill and tap it when the kit shows up.Would it work good in the LIM?

Doesn't ACV stand for Air Control Valve? which is a way to pump

air through different places with one source. (Me heap big somg

dude https://www.nopistons.com/forums/pub...DIR ) if I read the operation of the valve correctly, and I

could be wrong, you would just be dumping it into the exhaust.



j9fd3s has the better idea with the injectors. NOS has

developed some spray nozzles (they call them Nossles) that

fit between the stock injectors and the intake manifold :bigok: .



call me sacreligious, but I do own a 1991 integra as well :redface:



so far the rx and the 'teg are about equal. https://www.nopistons.com/forums/pub...IR#>/dunno.gif

but going around corners is a lot more fun when you are

sideways!!

Hey I got a 91 integra also, makes a good daily driver/beater. Good cars..



But anyways, what if you put them where the OMP nozzles go on the rotor housing? Or would you need more time for the NOS and the fuel to intermix before it hit the sparkplugs?

I was thinking about that too.But I don't want to pull the intakes apart again.Or I would just talk to NOS about finding another injector of the same style and drill the two intake runners on the Upper Intake and run the NOS right after the carb.I was thinking seeing as I pulled the ACV anyways why not mount it there seeing as the runner all join in lower manifold anyways.I'm just wondering if it is a good idea or not to mount the NOS injector on the block off plate.I could always fab up a intake system and run dry style thru it but I want a more direct route for it.Those nitrous injectors require more fuel lines to be run and for a small shot its not really worth it.If I was going with a 100hp shot then I would take that into consideration.I can't wait to see the flame on film racing at the track this year. :twisted:

Yeah I suppose if you don't want to take the intake off your kind of limited to where you can stick the nozzels. Do they just have a 1/8 pipe thread on them or something?

Yeah, If I can remember correctly its a simple pipe thread.Thats why drilling and taping will be fun no matter where the damn thing goes.

haha, no problem.... pipe thread is pretty forgiving. But I suppose it's going to be a bitch because you have to take off the piece that you have to drill and tap I guess... https://www.nopistons.com/forums/pub...>/blackeye.gif

thats why I'm thinking of using the ACV Block off.Just unbolt it and drill it.Plus it looks like the best direct path into the engine from what I can see.That and the spray will enter both housings at the same time.

Sounds good to me https://www.nopistons.com/forums/pub...IR#>/smile.png

I'm thinking its the best bet.Then it'll inject in all the spots at once.Plus it'll look cool hanging off the side of the engine.Just need to finish working out the details with the guy I'm buying it from.He should be sending it out this weekend.

Yes it does stand for air control valve.But mine is blocked off and that line to the exhaust is capped off to so theres nowhere for it to go. :bigthumg:

how would the rx respond to the nos setup?

Probably crack the welds on the intake and blow out the floorboards https://www.nopistons.com/forums/pub...DIR#>/wink.png



J

Don't get me wrong, I understand that you blocked the area off.



But, you are blocking off the area to prevent an exhaust leak. Right?



when I took mine off to inspect it (12A), it had the inlet hose (from pump), outlet

hoses (to air cleaner and catalytic converters) and two check valves (one for each

exhaust port).



please test the area beneath the blockoff plate by removing it and starting the engine.



if it goes to intake, it won't start (BIG vacuum leak).



if it goes to exhaust, it'll run fine. (but will be LOUD!!) :bigok:



if vac leak, drill away :bigthumg:



let us know.

The stock hard line to the exhaust from the lower manifold has been pulled and capped off at manifold and the ACV has beend blocked off and the plated was sealed tight.No leaks here. https://www.nopistons.com/forums/pub...#>/biggrin.png It should work there isn't any techincal reason why it shouldn't.The car ran awesome all year like that with no problems.I just want to know if it would work good for a nos system to spray into the lower manifold like that.

But thats after I get two of the big ones.Then'll I'll have enough NOS to blow myself up. :squint:

I would hate for you waste precious NO2 by sending it to the exhust side of your

intake manifold. but then you have a 13B and I have a 12A... I could be wrong. https://www.nopistons.com/forums/pub...IR#>/dunno.gif

Same.Whats the exhaust side of the intake?I thought if everything on my intake is capped off then the only thing it can do is intake?

I'm learning....



Was there ports between the intake and exhaust (underneath) manifolds that

were uncovered when you installed the header?

Nope,Just the two exhaust ports.That why I think that theres nothing to do with the exhaust this way with my intake manifold.

try removing the ACV blockoff plate and start the motor.

I know it's a waste of a gasket, but if the engine starts

and runs fine, then you need to find somewhere else to

install the nitrous.



if it doesn't run (loud sucking vacuum leak), then drill & tap

the plate for noss and boost away!! https://www.nopistons.com/forums/pub...#>/biggrin.png

Yeah I'll try that when the kit shows up here and I can get the clutch to work right.

dude the ACV blockoff plate sounds like a great idea. I have I nitrous kit in my shop...I might just do the same.



The thing is that I already have a 45DCOE weber setup and I would have to go back to the nikki.



Hey you got any tips for a dual (as in weber) direct port setup? I'm thinking about just buying a couple of nozzles and plumbing a 70hp shot thru the primary runners. ANY TIPS???



ahh I got the lake cities sidedraft manifold type...

If you look at my sig.Click on the and wait for the pics to upload.I have the RB/Dellorto Sidedraft setup.If you have a pair of nozles then you could prolly drill the runners after the carb and have a nozzle in each runner.Just don't jet it too high and blow it up.

I'm thinking about buying a zex setup, for my 79 with the 86 engine and egi. It's a 55 shot, that should be ok, but i think i'll try to drill and tap into the upper manifold, just after the injectors that way it sould mix good, or would it be better to get as close to intake ports as possible???

Just as long as long as the intake runners all meet up with it.On your car that sounds like it would work good.Did you get it figured out yet?
