Best Injector Replacement for a VN

[dvspcs]

I'm doing some work on my sons VN Calias and have found one of the injectors are stuffed so I'm going to get a set of Reco Injectors, what model injectors would be the best.

VN,VR or VS

are they a direct swap or whould I run into problems

[xcop5l]

there a basic swap but use silicone spray or similar on the o rings coz they can grab and tear then youve got a leak

[dvspcs]

so the VS would be OK or just go for the VR one's

[xcop5l]

what i understand there all the same
maby the eco tec ones are differnt

[dvspcs]

Thanks looks like VS ones then

[1991_Vn2nV]

Yeah all the same flow rates etc... Go VT ones if you can man, from what i've heard they are the pick

[glowworm]

vn to vs are all the same VT are not they are different ..glow

vn to vs are all the same VT are not they are different ..glow

Define Differnt?

Define Differnt?

Im pretty certain they have a higher flow rate than VN to VS.

VN series 1, 8-88 to 10-90 uses injector number 0280-150-901 which flows 146.3 GPM @ 3 BAR. Resistance 14.5 Ω.

VN series 2, 11-90 to 10-91 uses injector number 028-0150-960 which flows 150.5 GPM @ 3 BAR. Resistance 14.5 Ω.

These injectors are also fitted in the
VG UTE 11-90 to 10-91, VP COMMODORE 11-91 to 07-93 and the VR COMMODORE 06-93 to 04-95.

VT - VY N/A, 09-97 to 06-03, uses injector number 0280-155-777 which flows 150 GPM @ 3.5 BAR. Resistance 12 Ω.

The VN - VR injectors are what is classed as an EV-1 injector pintle type which are open to problems when used at an incorrect fuel pressure, hosing is a problem if pressure is too low or too high and the pattern can also be forced too wide for the target area if pressure is too high.

VT - VY injectors are what is classed as an EV-6 injector which uses a multi orifice director plate style technology to better atomise fuel across various operating pressures. These injectors allow more flexibility in relation to operating pressures without compromising spray efficiency or fuel atomisation.

Awesome explanation and info there man, cheers...great post

Had my regulator replaced today, my fuel pressure was 80PSI instead of the reommended 40PSI.

[dvspcs]

Well injectors have been replaced with VR injectors, Fuel rail was full of crap cleaned it out and put in the reco injectors, car is running 100% better, thanks for the help guys.

So do VT injectors fit or not, because they sound like a better option if you can make them work. I would do this mod if it wasnt difficult.

[Emackulation]

Ive been told a few times that VT WILL fit.

[J_D]

I might have to go to the wreckers and check that one out. Should get more power and better economy from VT injectors.

Make you you change the regulator too then, the post up there^ says they need 3.5 bar to reach the same flow as a VN injector

[Full Spectrum]

I got some new Bosch ones about 12 months ago good shit they are. Under $300 great price too.

[PaRaDoX]

you can run carbly cleaner thru the injectors, it helped mine a fair bit pulse them with a battery, FXST01 nice post very useful

[FXST01]

Just bought a set of VT injectors off ebay and should have them in this weekend in a V6 VP. Best i charge up the camera me thinks, i feel a "How To" coming.

hey greenfoam, would that be needed on a VS?...i guess what im asking is how many bar does a vs normally run at?

[J_D]

I wouldnt think you would have to change the pressure regulator as the VNs1 injector flows 146.3 GPM @ 3 BAR. Assuming a worst case scenario of flow rate falling at the same rate as pressure (which it doesnt) the VT injector would still flow 128.5 GPM @ 3 BAR. Flow increases about 1/5th for each doubling of pressure so the flow difference would be insignificant, about a 6 GPM decrease for a .5 BAR pressure drop.

if vt injectors are rated lower. why put them in. i am a little comfused on this one..

[Emackulation]

I had my injectors running at 5.333 Bar, lol. My regulator was stuffed, Would having twice the fuel pressure wreck my injectors?

[J_D]

Because they are a different design that has a finer spray pattern, thus vaporising the fuel better. Should provide better fuel economy and performance.

EDIT: And if the VT injectors can supply the correct amount of fuel to a VT engine then they can supply the correct amount of fuel to a VN engine as they are the same size engine.
