Hello from Germany,
I`m looking for the partnumber of the original injectors of the 22b STI.
Here we want to make a scooby GC8 (EJ20G) a little bit faster. Itīll get a VF34 Turbocharger and now we need Injectors. Our tuner told us to buy original 22B STI, because those will run best he said. Unfortunately I canīt find the Original Subaru Partnumber of these injectors. Are you able to help me. Or do you know where I can get them new for a price fairly? As far as I know the original 22b are 440cc, do we need bigger Injectors or is that enough to run a VF34 till 310 BHP?

I`ll be happy about any tips.

best regards

440 cc injectors at standard boost pressure will go up to 352 HP but for your targeted power the injector duty cycle will be near 89% which will stress them. so, its advisable an upgrade to a 550cc set.

Thanks,
can you tell me where I can get 550cc Injectors for the car without need to change clips or fit with collars?

Can not sure but its almost impossible a direct fit.

Well, the injectors only doīt cost so much money, the collars and clips (which have to be bougth also) make the whole package expensive.

The Tuner holds the original Injectors of the 22B for the best fit with this setup and he meant that they have a flow about 550cc. (A member of the Impreza-GT-Club Germany agreed with you (22b Injectors 444cc) but in his opinion they run with more fuel pressure so they flow 550cc.) He advised us to buy original 22b injectors. In my opinion 550cc is better too but itīs not my car and I`m always looking at the next step possible when buying parts for my car. But my friend doesnīt want more power than this so I think the 440cc will be enough. At my own car I have an injector dutycycle of 92% at full power. Getting this dutycycle doesnīt happen more often than ones a week, because the traffic here doesnīt allowed it. Iīm driving this way over one year and I never had problems, Me and my friend have a similar driving style, thatīs the other reason why I think that the 440cc will be enough.

So can anybody give me the partnumber of 22b Injectors?

Thankful for any tips
