    Re: 2 piece upper plenums

    Using an 88+ turbo or 3.0 V6 cable and bracket should clear a 90 no problem.

    I made it as far as glass beading mine today in preparation for paint...

    Sorry I'm so slow. Hope to have mine installed on Mini in the next month or so.

    Looks to be the same way I did it - tapping on the back and using street ell's.
    No more ugly vacuum block!

    Johnny you might want to break off that pipe worm before you button things up.
    At a later time if that piece of thread shaving breaks off, it'll end up in a cylinder.

    Re: 2 piece upper plenums

    Yes it is the Consulier.
    Got the throttle body gasket today so installed it.
    The throttle cable bracket is for an auto, and do not need that part so
    cut off the too long part so it would fit with my 90 degree silicone elbow.
    See photo F for bracket too long....photo C for the photo with the bracket cut to fit.

    But as you can see, now the air box is in the way. (photo D)

    Also an issue on my car ....(photo E) this set up makes the need to extend the throttle body plugs.

    Only thing I am not sure of is how to deal with the air filter.

    Wow looks good Johnny! Looks like two bends welded together should get you over to the air box.

    Always did like this idea, kinda F1-ish...

    Scoop to a basic panel style K&N, might not be too hard to fab up, especially if you could use an existing scoop from the MR2 or Fieros, no idea on cost though...

    Re: 2 piece upper plenums

    find a 1990 8v turbo airbox to use instead.

    87-89 airbox




    90+ airbox




    That is if you want to run a factory style airbox. The 90 setup allows you to run a straight pipe to from the i/c to the TB without necking down to go through the airbox. It also has inlets and outlets that have the same area as a 3.5" diameter pipe so it flows more air. Sounds like you put a big cone filter on the car with this setup.
