    Identifying stock 88 turbo injectors

    Ok so I need some help here. It seams that the stock Nissan injectors arent that easy to identify or at least im getting my ass kicked trying. Here's what I know.

    High impedence
    Off of an 88 Z31
    Visible part number is 2341 64 01 and A46-000001

    What I need to know is are they turbo or na?

    **Disclaimer about JECS numbers. These numbers do not represent a Part Number, but yet a manufacture date and batch codes. There is no way to tell the flow rate of a JECS injector by the number alone! Color, connectors, and style are a "better" way to determine the injector you have.

    ^ what Vagabond said.

    Only way to tell the yellow top side feeds apart is to break on off and have it flow tested.

    I think I got some INFO.

    Left > Right: Side Feed Turbo, Side Feed NA, Top Feed Turbo, Top Feed NA




    There is info I found somewhere around the interwebs that post service campaign side feed injectors all look the same, "natural" (yellowish with age) but I can't confirm that.

    These are pics of my actual injectors.

    Ah, then yellowed with age. Thanks, I'll change that.

    Any one want to confirm that older side feed turbo injectors were brownish/burgundy?
