Paul,

What are those little ports in the rotor housing on the RX8 engine? They
look like small P-ports, no?

It appears they go all the way through to the inside -- you can see that
some material is hogged out from the housing.

I got these pictures from an article I found about the Renesis engine:

They don't go all the way through.

I believe that is high pressure air injection into the exhaust manifold.
Perhaps for cooling purposes or perhaps to light off the cat sooner
when the engine is cold.

Paul,

Look on the upper left side of the second picture.   It does look like a
1.5" hole in the inside wall.  Perhaps someone was playing with the housing?

Perhaps.

On a second look at the block SV it looks like some one added a small p-port
to a six port RX8 engine using the intake manifold water heating holes.
No mention is made of this on the web site.

Richard Sohn reports there is no value to keeping the side ports once
a p-port is installed.

The third picture is of a real six port RX8 engine. You can see the two
side ports in an end housing.
