    how about a 99-00 miata head swap.

    the 99-00 miata head is better than the second gen 1.8 head in terms of power capability and it has stronger cams to boot.
    the 99-00 intake manifold off the miata must be used as the protege intake manifold isnt compabitle, but the protege header and exhaust is.

    i know the miata throttle body is on the wrong side of the engine, but i think a custom air intake would work to solve that problem.

    the head does bolt right up to a bp 1.8 block as well. the fuel rail should interchange, as well as the various sensors on the head and intake.

    you guys think its possible?

    Don't think there is enough room at the front end of the engine to put the miata intake manifold and the air intake.

      I don't think the fuel rail will work . I believe it is a returnless fuel system with the regulator built-in in the fuel tank .

        our protege/kia fuel rail can be bolted onto the 99-00 head in place of the 99-00 fuel rail as i stated in my first post.


        basically, im wondering if the head intake and throttle body would fit into the engine bay or not. just by "comparing" my kia with a friends 99 miata, it "looks" like it would fit.

          The fuel rail isn't "bolted" to the head but to the intake manifold itself.
          There wouldn't be enough room for the 99 MX5 intake manny and the air intake itself.

            i believe that i would have enough room on my kia to route the intake tube OVER the top of the cam cover. and if there isnt enough room, a tastefull hood scoop would be well warranted.


            i am going to start looking for a 99-00 head, intake and throttle body from the junkyard. hell if the swap fails, i can awalys ebay the parts.
