I am just beginning to specify the PP manifold.   The first question
is what  I.D. should the ports be bored to?   Does the port size
depend on the intended operating rpm.  If so, then I want 6000rpm
ports. Does anybody know what Power Sport is using?   Secondly,  Does
the I.D. of the  port, the runners and the throttle bodies need to be
the same?   I have a set of dual 44mm (1.75") throttle bodies that I
inherited with the engine.   I don't know if they are original Mazda
or not.

Does anybody have a picture of the PowerSporst set up?  Can't see
much on their web site.

Last question is for Tracy.  Will the EC2 work with just two injectors?

Thanks,   Jerry
