Anyone use RDX 410cc injectors?

[14bcb7]

I am slowly building my turbo setup and I already have DSM blue top 450cc injectors but I am thinking about ditching them for some rdx 410cc injectors. anyone have any input? thanks.

They're OBD2 injectors. You'd need to wire properly for them.

Is that the only difference?

[deevergote]

I'm sure there are quite a few differences. I'm not all that familiar with the RDX injectors. They are designed for two completely different engines, and you are intending to use them on a third completely different engine.

Well I've seen a thread with someone who used it on an H22. so theoretically It would work. Just wanted to see if anyone had actual esperience with them. Thanks for your help though.

If they've been used on an H22, then yes, it should work. I mean, an injector is an injector... they squirt fuel. But you need to be able to wire them correctly so they can be controlled properly.

If you've seen it used on an H22, your best bet would be to contact the person that did it and ask them. The RDX is still quite new, which means the injectors are probably still pretty pricey. Most people that want something other than DSM injectors just buy new aftermarket ones.

the honda-tech guy's are using them and say there is a big benefit for turbo because of the conical spray.

im tempted especially since they only retail for 50-60 per pop?

edit: 37 bucks a pop.

Seriously? Wow... I expected them to be insanely expensive, like most OEM parts. Especially new ones!
Ok, I can justify that, if they can be had that cheap. That's less than $160 for a brand new set of injectors. Only good for low boost... but on a stock-block turbo setup, that's fine. DSM injectors go for $75-$100 usually, and they're usually just about as old as the engines they're going into!

How the hell is a fuel injector for a pretty much brand new TURBO vehicle (which is very uncommon to see from Honda) only $37, and something like... oh, I dunno... an EXTREMELY common throwout bearing for an Accord/Prelude runs nearly $60? (I paid like $40 for my throwout bearing with Richie's discount!)

i paid $175 for my rdx injectors. for some reason or another alot of new oem acura parts are cheap. helps out when you are trying to do an oem budget build.

idk but i really want to test these out and test the duty cycle on it. i dont want to hack my harness up so i should just make some connectors. I am, after all, in a electrical class for automotive this year.

[deevergote]

oneoffaccord just posted a thread asking about OBD2 injectors... apparently there are conversion harnesses.

Are we still in the OBD2 era? Or are these new things something else?

[wed3k]

where's that thread, i cant find it.

[deevergote]

Swaps, I think? It's regarding an H23 VTEC

[14bcb7]

lemme know if you figure it out. imma run these on my turbo project if I can

If your going to use them for your dsm project, you should get 450's instead.
The 450's are close to their limit at 10-12psi, so going smaller than that will limit your ability to make power safely, and increase injector duty cycle.

To be safe with injectors I wouldn't personally run them past 85-90% duty.
Last thing you want is an injector running at 100% duty then getting a boost spike, or unaccounted temperature change.
