    Bigger injectors for a S3

    Just doing some prep work for the S3 before it goes in for mapping

    Got a 4 bar fuel pressure reg on hand but i need some 440cc or bigger fuel injectors as my injectors will be maxing out when mapped as Badger said.

    looking to keep cost down so had anyone used ones from another make or model car?

    I have heard of Audi S4, Vipers, Cossie Greens and Vauxhal VX ones?

    Just ordered my so i think fueling will be on the safe side now

    They are meant to be 470cc at 3 bar i have been told not 440cc?, i have a 4 bar reg on standby if i need more fuel but i think the fuel pump will also be the weak point

    I think badger said the will max out at 320bhp ish on 3 bar but the fuel pump doesn't like 4 bar over a period of time the pump may fail, its best to keep the 3 bar pressure and swap the injectors
