DC2R Injectors on a stock b16a1??

[Dxs]

I have a full intake out of a DC2R.. injectors, rail, fpr, manifold.

Now i plan to install this on a b16a1.


I was just wondering, seeming as though i am running stock OBD0 for now, is it possible to use all the DC2R setup?

I heard they are both 240cc injectors for both dc2r and b16a1.
Is there any difference in the FPR? I presume DC2R is a higher pressure in the rail? Do i need to swap them?
What about this resistor box setup that the b16a1 has i believe..
?

What year DC2R did the setup come off of?


If it's OBD2 they're saturated which means they do not require a resistor box. you will need to use your factory B16a injectors, as they're peak and hold. peak and hold injectors require the resistor box which is already wired into your factory harness. whereas the OBD2 injectors do not. either fpr will be fine.



PS. great work mang!

2000 apparently
so are the injectors the same cc?
what is the rating of the FPR's?

Can i remove the resistor box for the injectors and keep obd0?

Both sets of injectors are 240cc

The FPR's are different, the ITR reg giving a higher pressure,so your better off sticking with the B16 FPR with your stock ECU.

Yes,just remove the resistor block & join all the wires together to convert to the ITR saturated injectors.

[Dxs]

ok..
so basically use the b16a FPR on the itr rail
and look into removing the resistor box..

and the fuel should be ok using stock OBD0 ecu?

[CRXer]

yes,fuel will be fine cos uve effectively done nothing, with the B16 FPR in place, except convert to higher impedance injectors which the ECU transistors can handle without having to have resistors in series,they have the same flow rate & all uve got is a fuel rail which is compatible with the ITR manifold.

[JohnnyVtec]

You can use either one of the regulators you have, the itr fpr will work without any problems incurred!

[Dxs]

so you are saying itr fpr and b16a1 fpr are at the same pressure

i have the itr injectors and rail and fpr.. would rather use them because they are perfectly mounted then use the b16a1 injectors because you have to fiddle with removal of the spacers etc/a little dodge

[JohnnyVtec]

Both fpr's operate via a vacum accuated diaphram which is spring loaded=the lighter the spring the more pressure flows. I am not aware of any difference between the weight of the springs in the two variations of fpr. I can say with extreme confidence that if there is any difference between the B16a/B18cr fpr's output it would be miniscule........




You don't want Dodge, you want Honda

There'd be roughly 10psi of fuel pressure difference between a B16A & a B18C
I'd be using the B16 FPR........

WOW so how are you prepared to provide verification that your claim is valid? What is the standard flow rate of a b16 fpr, also what is the standard flow rate of a B18cr fpr? Where was the flow measured from? Was the flow measured from multiple locations so as to eliminate fluxuated readings? I hope you're not (assuming).

I know a standard B16A should have a fuel pressure reading of about 40psi(with vac disconnected) & a B18C should be roughly 50psi(with vac disconnected),I remember this from service manuals.
