Compare the places where you could make the manifolds meet by looking at the gaskets here: http://www.mazdatrix.com/c-2.htm



I'm looking to do the same type of thing because of going turbo, and the only way I can figure to do it is fab a spacer to go between the upper and lower intake manifolds (about 2inches is needed to make the FD UIM clear the housings). Between the UIM and LIM is the only place the ports are close and the bolts match.

if where they meet is relatively the same size you can press studs into the holes and redrill to match the other. just make sure that your runners line up.
