Title: injectors
Post by: laney101 on 09 May 2016, 12:09:19
Im wanting to get a spare pair on injectors to have them cleaned and then swap mine out

Queation is is there any difference between 2.5,2.6.3.0and 3.2 injectors some blue some grey...

And is there any benefit to fitting blue ones from 2.5/3.0 to my 3.2?

No because they're smaller ;) one of the reasons the 2.6/3.2 is marginally less economical...

So the 2.5 and 3.0 injectors have a smaller flow rate.. is that at same pressure or different pressure

Non DBW cars run a fuelrail pressure of 3.0 bar, DBW cars are at 3.5 bar :y

Got a set of injectors on the 3.2 breaker :)

Would hope OP has a set on his too, but you never know... might be a sale nonetheless  :D

Now I seem to recal, don't fit 3.2 injectors to a 3.0, as they drip. But a 3.2 regulator in a 3.0 is good.
Don't know what 3.0l injectors in a 3.2 be like :-X

Vectra/Insignia VXR injectors and regulator will get more fuel in, but good luck getting the ecu to keep up...

You need to get more air in too, or you just get unburnt fuel, washing down the bores. Or filling up the pre-cats and causing flames out the back,,,,circa late 80's touring and rally cars..

I wonder if the next question will ask which hotter/colder/shinier/gimmicky sparkplug is 'better'?

Or which air-filter,, (KN,piper-cross, or big cone strapped to the airflow meter.

Not really no and arsy sarcasm isn't welcomed

Who mentioned vxr injector because I didn't? They Wouldnt ever be of any use. be high flow rate for turbo application.

I asked about 3.0/2.5 because got offered a set simply seeing if same flow rate and work ok .. They aren't same so all good I'll hold out for 3.2 injectors

Altering spark plugs only good if altering thermal efficiency of engine or running forced induction to get right burn.

Air filter pointless half the time a cone will cause heat soak and a updated panel filter will kill a man sensor or not be as efficient as a genuine one

Why ??? Surely your 3.2 already has 3.2 injectors...

It's comments like that which encourage the sarcastic responses... A bit like saying I want a replica stock exhaust in stainless but want it to sound different and have a cross flow pipe... :-X

........kill a man sensor......

Not being sarcastic but that mistype made me laugh, the ideal sensor to be fitted to a young lady's first vehicle.  :D

Fuel rate isn't an issue on any Omega, and seeing as forced induction isn't really suitable for the V6 (Ok, maybe the 3.2 could take very light blowing), sticking to the right ones is the best route.


As I'm sure you know, all the usual BS in the likes of Max Power and Courtney catalogues is a complete, total waste of time, written by chavs not knowing their arse from their elbow (in case of journalists) or because they know a fool and his money are easily parted (in the case or some commercial outlets).  Uprated FPRs and bigger injectors just cause the ECU to trim it all back, but making it less efficient in the process.
