May I using mixed injector?

[ej22t]

Hi people, just has problem on my engine and needs some infor help from you guys.
The shop just find out that one of the injector is dead. Since the engine was swap, I keep using the old EJ22T injector (pink top) on the new EJ20G engine because one of the injector from the EJ20G was dead when the engine arrive, thats why I have 3 EJ20G (gray top) injector in hand that will be my spare parts.
My question is can I use one of the gray top injector mixed with the rest of 3 pink top injector? Since the fuel rail are same will it still have to make any problem?

Thanks for all your input and help!

Not a good idea!

Pink top (EJ22T) Injectors are somewhere around ~370cc, and the Grey Top (EJ20G) is a ~440cc injector...so if you were to use three of one type and one of the other, a different amount of fuel is going to be injected into the cylinder with the mismatched injector... This would cause some problems, most likely detonation from lack of fuel in the one "black sheep" cylinder.

Definately stick with all 4 of the same type of injectors.

Thanks Nick, I will go to the junkyard to find a pink top for the fix.
