I'm sure I'd still be longing for more weight loss, but I can understand entirely that modern day regulations prohibit the days of the FB. :lol:

And the reasoning the Renesis can't make the power older rotaries can is because of the ports. Older rotaries (ie - 13B-RE and 13B-REW) utilized large intake ports. The Renesis, albeit large, is also sacrificing port size due to its six port design (at least in the manual version), and therefore you can't have the ports as large. If you made a solid opening for the intake ports in a Renesis, however, you'd sacrifice your low end torque, and let's face it, it isn't a grand amount down there.

The six port design for a rotary only works excellent as a means to stay naturally aspirated. Four ports are what you want for a turbo application. Having said that, I am really curious as to what would happen if you ported a four port to have the same closing timing as a six port, and turbocharged it using lower compression rotors. If I had way too much money I'd test that out. If you'd notice, though, all the turbocharged rotaries that Mazda has ever produced have been four ports. Good reason for that.
