    Would 555's be sufficient or overkill for 350bhp on an SR20det? I understand going too large can hinder performance..
    Fairly basic setup:
    u13 highport SR20det
    tomei expreme mani
    GTiR ECU + nistune
    GT2871R .64
    Z32 maf
    fmic

    contemplating forging the bottom end but it's super low miles so should handle 350bhp for a while with little abuse I'd imagine.

    I recomment 740cc for an GT2871R on a SR20. With normal boost (1.4bar) you will get about 400hp. If you have to small injectors, the injectors work on its limit, getting hot and decrease there lifetime. Dutycycle at about 75-85% is okay.

    Best Regards, ludi
