Fuel injector questions

Post by **subzerocarfanatic** » 18 Jul 2020, 12:30

I still have not resolved my electrical short issue, i'm taking a break from it for a bit.
I have the fuel rail and injectors pulled out and want to get a rebuild kit for them with seals,filter etc. , does anyone know if there is an OEM kit or have a part# please!
All the injectors Ohm out at 12.5 is that about normal for these,it has the BOSCH
9186060 0280155830 injectors.

I have another question....can the green injectors used standard on the 2000 V70 R rated at 468 cc/min? I have the blue ones in my C70 2.3 Turbo which are rated at 395 cc/min I believe. I know the white and the blue injectors have the same flow but different specs because different Volvo models have different fuel pressure so theoretically the whites could be used in a different model with higher fuel pressure,I was just curious if anyone has ever tried using the green ones in the C70.

The green injectors are 440cc/Min @ 43.5psi. There is no sense in using the green injectors unless you push enough oxygen into the cylinders to burn fuel at that rate. R and T5 owners with the K24 turbo can do it.

So if the turbo was upgraded then.Not doing it now just things to consider in future.

Turbo upgrade, tune and injector upgrade. If you just want it for wide open throttle applications, a dry nitrous system and injector upgrade will do.

Never change injector flow rate unless you also install a tune that matches the new flow rate. Never.

Fuel trim "tunes" the air/fuel mixture.

Ah yes, rely on fuel trims to take care of the mismatch. Great way to run occasionally rich, occasionally lean.
