    B18C7 Injector Replacement

    Hi guys, I am looking for a bit of help with a question relating to injector size and the supporting mods that is required.

    My DC2R has upgrades to intake, header, exhaust and ecu. Running very well, so much so it actually maxs out the stock injectors (which I believe are 240cc) at 8000 rpm.

    I am considering upgrading these to RC Engineering 310cc or 440cc and would like to know if anyone else has done this or know of another brand worthwhile.

    At the same time I presume I would need a re-tune (not sure if full re-tune or partial), but what about a fuel pressure regulator, fuel pump or fuel rail?

    Any tips would be appreciated.

    Cheers,
    Luke

    I contacted my tuner and they stated I only need the larger injectors and a re-tune.

    Also I think it would be possible to just up the fuel pressure using a FPR but the injectors are 16 years old.

    What do you guys think?
