Can anyone tell me the difference between the bosch 0280150558 injectors and the bosch 0280155968 injectors? I need bigger injectors for my 240+T build, the 558 injectors look to be the same shape as my original 240 injectors and the 968 models look to be the same shape as the 850T injectors which some others suggest to use. Again, any help is greatly appreciated!
They externally look similar, colour is different though, I recall your car is only a +t with a stock turbo?
Yes, stock td04 from 940. I have the 558 injectors but I have been unable to get them to spray. I have the 3 bar fpr and the turbo ecu and fuel computers installed.
They are way way way too big for a Stock Turbo, unless you are going run E85. I got some 0 280 150 785, which are 315cc, I think should suit you heaps better (PM me if you are interested in buying). TD04 from 940 is it a 13c ? You can see the TD04- _ _ C/G/T, which will help to find you the best injectors. 13c are tiny tiny turbos, even if you run like a 15G or a 16T from a 850R, 315cc should be good enough. if you run 440cc injectors i think it will be damn rich and lose a lot of Fuel Economy and lose quite a fair bit of power
Unable to get them to spray? Did you fit the resistor pack off the 940? They are high impedence and need the resistor pack, Though n/a cars should have that too...
Yes its a 13c, and no i don't plan on running e85. However, what would prevent these from working? Even if they are much too large for my application would they not still work? Are the 0 280 150 785 injectors high impedance?
@Vee_Que I thought you don't need resistor pack for high impendance ?
@90gabe 785 are high impedance as well, have you try start your car with stock NA Injectors? Just don't boost it, idle doesn't need much fuel and even running lean doesn't really matter. If your car start with stock NA injectors and don't run on the bigger injectors, there might be a problem with the injector itself, try measuring the ohm of the injectors wif a multi-meter
