Default Re: injector size???

Someone said 560cc for the STI, which should be good for over 400hp (75% duty cycle, fuel rail pressure around 40psi)

Anyone know what the stock fuel pressure is?

Factory rate injectors

USDM WRX 410CC
USDM STI 534CC

As most of you know the pink STI injectors flow 565cc but factory rate those at 520cc. WRX flow 440cc and factory rate them at 410cc.

Just guessing the New UJ USDM STI injectors would flow a little more than 565cc.
