Don't know Your backrounds, but injectors are not way to start project, 400hp is a lot and You have calculate injectors more :/

It's been an ongoing project since 2003 mate all forged custom inlet big turbo. Soon have big valve head I don't like going over kill with injectors like big 800 or 1000 to much hard work getting them to idle right. Am sure 540 at 3.5bar will be about 650cc any ways

Go for a twin rail setup

Been pretty close to 400 on 540s at stock fuel pressure

On decapped 540s now roughly 800cc no issues to report at all
