    Default 4ac intake to 4afe intake

    I just did an engine replacement for a mate, and kept all the unused parts.
    I have a 4afe (~ ae90/ae92 injectors in head) intake manifold and throttle body.
    I read on the old forum something along the lines that this intake bolts up to 4AC?

    Anybody know before I go pulling shit apart?

    It does not bolt up. The EFI manifold could be used to convert a 4cyl motor to EFI, after alot of cutting and welding.

    The 4A-C has both the exhaust and inlet ports on the same side, the 4A-FE is crossflow. This makes things a little harder.

    Is there a injection manifold that is a direct replacement for 4ac? 4ae?

    There was a 4A-E with EFI, but not in Australia. The manifold would be very hard to find.

    What country was 4A-E injection released in?

    Reason I ask is i have SC14 here thats been doing nothing for 2 years,
    a fuel only microtech, injectors, rail and a efi pump...I figure why not?

    The other option would be carbi fed. Do webbers work with boost?
    Would I have to put the webber before SC14 or after it if I went that root?
