i thought atomization was based on the fuel/oxygen mixture. i dont think getting injectors alone will improve horsepower.
Atomization of the fuel is different than your air/fuel ratio....

atomization in a nutshell= how fine of a mist your fuel injector can spray the fuel into the cylinder.

The finer the mist, the better the atomization and better oxygenated your fuel will be entering the cylinder, netting you better a better burn, and generally MOAR POWER!

think about a water gun and mister. the mister is a fine spray which covers a lot and is easy to mix. Vs a water gun that can output alot of water but is normally in a spray that only covers alil and wouldnt mix well .
Something like that, sometimes i suck at explaining stuff but its all in my head.


updated my build with hi res pix.

RDX's were good 4 years ago.

Now a days when you compare cost to CC outage there is way better options out there. Siemens Deka 4's are one of the best, they have them in 60lb/hr, 80lb/hr and 220lb/hr. That's 630cc, 875cc, and 2433cc this is at 43.5psi. Prices are even better $49.99/$54.99/$169.99 respectively(This is MSRP you can find them way cheaper). You don't need any adapters or spacers since they have them in both 48mm and 60mm sizes and both EV1(OBD1) and EV6(OBD2) connectors.

Last time I checked ID's still needed spacers and adapters and cost way more....

EDIT: Yes you need to open up your fuel rail by 3mm's for these to work but that's nothing, took me less then 3mins to do it on my stock rail. They sell rails now that are already 14mm too...

That's excellent information. Thank you for sharing. However, those are way large for my needs, and the RDXs are perfect for almost everything I have planned. However . . . Those 630cc units in the long size . . . That is a really good fit for a certain application I have in mind.

I ran rdx injectors in my d16. They are nothing special. I would personally just get dsm 450cc for the price. I have used both.

I do have my rdx injectors I will be selling with obd1 plug and play harness adaptors and the top fuel rail adapters. Just needs some new o-rings. Keep it to pm if you are interested.

Ok i did search but i just need a confirmed answer.
Should i go with the Acura RDX 410cc injectors?
They are said to have the best atomization, and cost around $50 ea. shipped.
I look up the install, and from what i have read is all i need are the clips and 14mm to 11mm adapters.
I can get all parts from xenocron rdx

There price is good and i like the fact that i can buy one injectors at a time from an online dealer ship vs dropping $200-$300 at one time. Right now its easier for me to spend $60 a wk then $200 a month at one time. I can save money but its hard when your girl knows you have money and wants stuff.

So my questions are.

1.) Install. All i need is clips, 11mm-14mm adapter, Cut the tap at the top. Do i need different o-rings for the bottom where it goes into the intake manifold? Factory RDX or civic?

2.)Are they good injectors to get? I read something about them being a little slow and lagging some. But easy to fix just by changing the offset.

3.) Will they run on stock fuel psi? I read that to flow right they need 50psi vs stock 43ish.

Power goal is right around 200whp. I know they will flow that much. Just asking about the install and the injectors them self.

Yes i know i can get some RC injectors used for around $100 then pay about $40 to have them clean.(dsm for $60-$80).
But hell why not get new injectors for a little extra right?

Thanx for any help you can give.
Posted in FI because they will go on a turbo car.
I have a question I am writing the same injectors on a B series and I have my OEM harness would I need to buy adapters and if so where can I buy those clip adapters I already have my key to top hats and I feel like my car is not starting because I still have the OEM clips on someone please help:(

9 years old guys.

Besides, dont buy RDX injectors on ebay. maybe ONE set out of the hundreds of postings, are OEM. the rest are shitty garbage FAKE injectors.

Buy them brand new at a honda dealership or website. Or a performance shop's online store. ONLY way to guarantee OEM injectors anymore.
