I'm having a speed shop modify the eccentric shaft so that it only has one rotor journal and moving the front key-way to the other side. Then hardening and balancing and bolting it together with one rotor. Port both the primarys (because all it has are primary intake ports) Custom intake manifold and exhaust, tiny turbo, inter-cooler, Mega Squirt fuel injection and to handle the ignition and maybe the metering pump, adapter plate, oil cooler, custom motor mounts. I still haven't sorted out the clutch yet. And then you get a single rotor 13b Subaru, or Rutaru, with 650cc's of furry.
