From my other (XE stuttering thread) thread andy suggested that i could have a fubard injector anyways my mate given me a set of Late dispac blue ones do these give any pros/cons for the beige ones i have in at the mo?

Do they inject more/less fuel etc?

I *think* they have a higher pressure??

[joff-turbo-nova]

If I remember correctly the Fuel Pressure Regulator runs at 2.5 bar on a dizzy engine and 3.0 bar on a dizzyless.

The injectors have a different flow rate. Put the Bosch part number in a search and you will get the specs for them.

And if you plan on using then get them cleaned and tested first - you may just be changing poor injectors for more poor ones !

Joff is correct, require more fuel pressure than the beige injectors and not sure how they will run on the wrong management.

Cheers guys for the replys the injectors i was given were cleaned around 3mths ago and they ran fine in the dizzy Xe he was running i was just curious as he said that they may inject more fuel but as bazils post show they do lol.

Also im running the 3.0bar reg anyway and mines a 92' XE.

Damo.

gimmie a minute ill post the flow rate for both cream and blue at 3 bar

hmmmm according to the flow rate chart i have it says both the cream and blue injectors put out 250 cc/ min at 3 bar :wtf:

A mate of mine's running blue's in his dizzy 20xe.

if you're running the 3 bar reg on the injectors that normally run on 2.5 you will be fuelling wrong, which may have been your original problem....

Tbh mk999 i never thought about the pressure as the engine came as it is now with the 3bar reg on ill swap the creams for blues then and see how that goes but like you said if im running 3bar on injectors that are meant for 2.5 then that could be the problem!
