I was looking at a 20B P-port originally for my project.  But since the 20B engines are getting harder to come by and Mazda has started discontinuing parts for the older engines, I have turned my eye to the renesis as an option for future availability of parts.  I know the renesis is a whole new ballgame in terms of porting from the earlier engines.  What porting is being done with the renesis, and what is the reliable hp that you would expect to get?
Thank you,

I don't recommend porting. I recommend P-ports.
They are easier to build manifolds for and easier to predict
the power out. In general 25% more than the best porting.
Over all cost is lower. 250 HP for a 2 rotor and 375 HP
for a 3 rotor.
