Will my 3.0 injectors fit in place of the 2.6 injectors on the inlet manifold?
TIA :y
-
They will physically fit. I can't remember if the spec. is the same. 2.6/3.2 injectors run at higher pressure, IIRC, so likely different flow rates, and the fuel pressure regulator will be different.

Cheers Kevin. I'm after an inlet manifold and one is being offered for a fiver on here. Just needed to know if my injectors will slot straight in place of the 2.6 one's?
Ref the fuel pressure reg, is that part of the manifold?
-
Its on the fuel rail :y
-
Right, ok.
So really that doesn't make any difference then?
I can take the 2.6 injectors out, replace with my 3.0 ones and put it back on again?
TIA

And you can just swap the fuel rail over if needed :y

Sound as a pound, cheers guys! :y

Beware that the 2.6/2.5 manifolds are different to the 3.0/3.2 ones, though. The intake tracts are very slightly narrower. If possible, find a manifold from a 3.0 or 3.2.
-
Oh bugger. :'(
At least I've found out now, cheers Kevin.
I'll let the seller know now, as he's holding it for me! :y

Difference is negligible

Difference is negligible
Perhaps, but you'll have a step between the 2.5 intake manifold and the 3.0 divider, which is a bad thing. GM wouldn't have produced 2 different parts with a "negligible" difference unless there was a good reason.
FWIW, if the reason for changing the manifold is just to eliminate straw nozzles from the LPG setup, I'd not bother at all, if it's now running well.

It's deff running better now James did his magic on it. iirc, he suggested changing and re-routing the rest of the pipework and then to set the LPG injectors into the manifold.
So do you believe, other than renewing the rest of the pipework, leave it well alone? A case of it's not broken now, don't fix it?
Just waiting to see if my petrol consumption will slow down as I was going through 1/4 tank petrol every 2 weeks roughly, whilst running on LPG. :-/
-
Well, it's a case that if I were converting it from scratch I'd fit nozzles into the manifold rather than to use straws, as the latter is a little unsightly and really only saves time for the installer.
Having said that, if it now runs pretty much as well on gas as it does on petrol that's all you will ever achieve, so if it 'ain't broke?
Of course, I haven't seen the car in question. I just wouldn't swap straws for nozzles on a car that was otherwise running quite happily on LPG with a satisfactory install. :-/

Fair enough.
Not being a mechanic and picking bits up as I go along, I listen to the advice I get from you guys & girls who do know.
Thats why I end up asking stupid questions even on the simplest things! :)

Nothing wrong with asking. :y That's how we all learn.
.. and if James spotted an issue which I haven't appreciated with this particular car, then my advice might not be relevant, of course. ;)
Of the issues James mentioned it's the coolant plumbing to the vapouriser that really needs fixing, IMHO.
