I´m trying to determine what kind of injectors are the recomended ones for a TD05-20g turbo like on a MY03 STi.

I will like to know if I can keep the OEM ones (wich will work with a Walbro fuel pump).

It seems that the US guys always go for the 'bigger is better' route, and I have been adviced to get at least 800cc ones if I choose one of the listed above turbos.

Thanks in advice!
