Does anyone know the flow rate of the STi injectors? I know a lot of people say they are 555cc, but according to the APS website, they state, and I quote, "The 2004 model US Specification STI is a unique model in many ways. Just some of those already identified are as follows: 1 Side feed 480 cc injectors (350 flywheel horsepower at 11.0:1 A/F ration, 100% duty cycle). This is in stark contrast to the International Specification vehicle with its 565 cc top feed units". Just curious if anyone really knows the flow rate.
