What is the installed weight of a 12A?

Richards single rotor (using 12A rotor and rotor housing) is about 170 lbs
at the moment, which is really low because he custom made so many items on
the engine to save weight. Using stock Mazda housings would push the weight
up to about 220 lbs at the most.

A 12A is normally a two rotor engine, which weighs pretty close to the same
as a 13B. We generally use a figure of about 330 lbs for firewall forward
weight of a two rotor.

Cheers,
Rusty
