on the other hand, auto manufacturers aren't looking at just power output.
Once you start porting engines, playing with tuning etc, the fuel economy, drive-ibility, reliability, etc change. Emissions comes into play. The switch from the 4 port 13b to the 6 port 13b was probably just a function of the above. Plus Mazda seems to enjoy experimenting with new ideas.
