    What an interesting piece. Any idea who makes the injectors?

    That would be good for someone who wanted to do a dual quad tbi efi setup. Still be able to run off tbi ecm.

    Hi
    253 car guy contacted the guy making these.
    here
    They are not plug and play but still a good idea.

    In a few weeks I will be rebuilding my TBI when I do I will use the renishaw on my CNC to trace the intermediate gasket/spacer and come up with a G-code file for the same thing. I just have to schedule the down time on my daily driver truck.

    I am working an idea to make a bi-fuel setup for running E-85 on the old TBI motors.
    I have to get over to the junkyard and find a really cheap FLEX fuel sensor to measure the alcohol content.

    My thoughts now are to use the flex fuel signal to trigger an old style boost injector driver circuit I outlined on the forum a couple of days ago.
    This will enable the proper ratios with the stock injectors supplemented by throttle plate spacer injectors.

    With this guys idea I should be able to shoe horn two injectors per bore accomplishing the same effect.
    I will keep the stock pressure regulator but inverted so it is easy to adjust.
    Have to find a diaphragm that will handle @40-50 psi
    Thinking of using either the econoboost fogger injectors or a set of 1400cc SRT injectors.
    Both have the 14MM diameter body.
    If I bail on the top mount I will definitely use the econoboost under the throttle plate.
    I use econoboost in my LT-1/4 engine but never sprayed them in mid air so I will have to see if they make a mess when above the throttle plate.

    Be sure to take pics and post up how things turn out. Which ECM/PCM will you be using?

    the repair part number is 88961143
    I have not pulled down my Suburban ECM yet.

    My goal is to make a bolt on upgrade ready to run.
    I put an AC Delco EP376 fuel pump in and I know that it can supply a tested 60PSI on an LT-1.
    SO I will put a kit part list together so anyone can buy the pump and injectors they need I will supply the machined parts.
    Not really to interested in selling injection hardware but the kit I think people would like.
