What is 20B 3 Rotor?
Can anyone lead me to where i can find info on the 20B? Can't seem to find a definition of it anywhere on the web. What's the difference between that and the 13B? Can it drop into an FD? Sorry, newbie....

Well, were a 13B has two rotors and a capacity close enough to 1.3 litres (hence the 13B) the 20B has 3 rotors and is close enough to 2 litres. Basically it's just got another 13B rotor and housing. The rotors are the same width.
It came in the Mazda Cosmo or Eunos Cosmo with twin turbos. It makes a bucket load of torque due to the increased capacity.
Yes it can be installed into an FD but it's not something you can just do on the weekend.
They're pretty much the ultimate rotary motor (factory, not counting the R26B) and are fairly rare due to the smallish numbers of Cosmos made.
