3-Rotor 13B Engine

Now , let us get this straight... this is not a 20B Mazda engine. It is a hand made 13B engine with 3-rotors. Built using a custom manufactured crankshaft and a modified 12A Series 3 centre plate to accept a stationary gear , this is one unique engine. A 20B upper inlet manifold and throttle body are used but the lower section does not fit because my engine is shorter , so a custom made lower section was fabricated. The engine uses the front mounts with a custom cross-member leading to standard engine mounts.

Thanks to Jeff Bruce for the pics of my engine internals.
Although not my exact parts, they are very very similar.
 
 


This is a 13B plate by the look of it , mine are 12A with no injector holes.
