    Default Can i/ should i upsize injectors on a standard motor.

    Hi all. Recently attempted firing up my RA23-1JZ after sitting for 5 yrs.

    Wouldn't fire. Found fuel leaking through very shitty hoses.

    I've decided I want to service the injectors before trying again however I've been quoted $240+ to have them done.

    I've seen new sets of injectors on ebay for less.

    My main question is if I do buy new ones should I or should I not upsize from the standard 380cc to 440cc?

    The engine is stock standard. Any advice is appreciated. Cheers.

    There is no benefit in putting larger injectors in a stock engine with the factory ECU. Likely result is that the engine will run rich.
