Holden Injectors in to a ford??

[get_an_ea_today]

Hey guys, I was browsing on ebay and I came across this XG ute that said it had VS Commo injectors? Now he also said not to ask just that they make a big difference.

Has anyone heard of this? and if so is it worth doing?

Cheers,
Matt

I might be wrong but I think E-Series, 90s Magna and Commodore injectors are interchangable and have similar flow rates (19-24lb?)

I'm not sure about Commodore injectors but I think Magna ones offer an improvement over std E-Series 19lb units

I bought my injectors of v8capri who had them in his VN.

[BaYa]

i think im not sure but the magna blue top injectors are the one you want if ya want injectors.

[get_an_ea_today]

Oh well there ya go lol. Would it be worth changing the magna injectors or is the difference minimal? Would you need to change the ecu?

i'm assuming that we qre talking about 6 cylinders?

[burnz]

holden run a return to tank setup
whereas ford don't
the holden fuel pump run at 60 p.s.i. in that thier is your answer

sorry if it vaigue!
you may need a holley blue and a recale of you softwear
to get the benefit's other wise pointless

wouldnt putting in VN/Manga injectors over fuel a E series if running standard ECU?

possably yes
as the vn/vr run 23 p.s.i. injectors
(note i don't know the ford fuel pressure this may leed to over fuelling)
as the holden run return exess fuel for the fuel with is not needed

Falcons have a return line as well. And injectors aren't measured by pressure.

[bentles]

23lb injector, the lb is for pound right? but not pounds per square inch?

i dont know how the ford unit works
but holden goes bye 125milliseconn@60psi =idol
to a max .925 milli @60psi if this helps
vn/vr injected fuel before the intake valve opened @ 12psi (poor atomisation)
ecotec injected while valve open better fuel efienct @60psi

lb is pounds per hour. A 23lb injector will flow 23 pounds of fuel per hour with it wide open, at it's specified pressure.

From what I remember the Magna/HSV injectors flow 23lb in Magnas and HSVs, but the fuel pressure in the Falcons is lower so they flow 21 or so.

If you don't know how the Ford systems works why say Ford don't run a return? VN-VR run a hell of a lot more than 12psi.

Any injector change to a different flowing injector will require a ECU change to get correct fueling, if you change the fuel pressure to get it correct, you will have no benefit at all, and actually may be worse off due to incorrect spray pattern due to the pressure change.

[trick_xd]

fords run rich anyway .. and there has all ready been threads on this over the years .. not much point putting in bigger injectors with out needing it

[TICKFORD_XR6]

on an EA engine with an EL XR6 ECU, will EL XR6 injectors make a difference?

because a mate of mine had an EA
and i noticed it didn't run a return (not that i seen)
reapairing solid heater pipe.

the only real gain you are going to acheive by running bigger injectors is if you have a DIRTY BIG cam and advance the timming otherwise the stock injectors will be able to produce the amount of fuel needed. personaly i wouldn't bother unless you are going boosted.

Hmm thats a good one cause i have been thinking about that. Does any know?

The ELXR6 ECU will be calibrated to the BBM intake and thermo's and smartlock, and the ELXR injectors are the same as a EA, im pretty sure when they went AU there was a slight difference, but still then they run at 19lb. The XR ECU will run the fuel pressure at 300kpa thats about it, and be calibrated to 3.45 Gear Ratio...

If im wrong, please correct me

cheers

Do you need a 3.45 diff to run the ecu in a ea?

nope, but if u have a auto, and you leave it in D, it might shift up earlier
