I had to adjust a few things based on Don Dunbar's dimensions.

This manifold layout is just about the only way to get the
proper length for the runner tubes and still keep everything
under the top of the cowl. We will shoot the fuel
in from the trumpet end. BTW the RX8 injectors are much
easier to use for a p-port as they are only 5/8th of an inch
in diameter. Two side by side can be on 3/4 inches centers
rather than the one inch centers required by the Nippon Denso (Mazda)
and MSD (GM) injectors.
