no i'm not kidding, only thing you can do is increase compression and that isn't going to gain much unless on a turbo setup and then you become limited or need to run alternative high octane fuels.
rotaries are not "grunty" engines like say a V8 is. their power is made gradually and at higher RPMs, more like a 2 stroke engine. only other way is to add rotors, like a 20B or the one off 4, 6 and 12 rotor engines.

Some options:
- 20B, V8, or other larger displacement engine conversion
- Correctly-sized ball bearing turbocharger (contrary to popular belief, boost produces torque)
- Roots or Lysholm type supercharger (but not a centrifugal type)
- Weber EFI throttle body or carb conversion kit with long air horns, combined with a good exhaust system.

Here is an example with a 20B FD, and you could just apply the same concept to your 13B:
