They have discontinued making this engine about 3 months ago, ive researched it for a while. Its a single rotor equivallent to a 12A mazda rotor. This engine produces godzilla power for its weight and size, the power to weight ratio is just insane. Its got the whole she-bang as a real rotor (eccentric shafts,apex seals, etc.).

Its real hard retro-fitting it existing cars, lots of of custom mods need to be done.
