3 Rotor Tech - Can you use 13b parts to make a 20b? Cosmo, and FD3S side plate discussion - KMR

Talking about what parts can be swapped between 13b and 20b. There is a lot more to this than discussed in the video so I will talk more about 20b parts and what is unique and what is not.

Glad you talked about short crank 20b I've been curious about those

[@jaredrule1431]

Plenty of components for short crank engines being produced here in NZ. We’re fortunate enough to have the global guru of custom rotary eccentric shafts and machining based here.

[@KyleMohanRacing]

that's awesome. Don't see many over here anymore.

[@jaredrule1431]

3 rotor, 4 rotor, 6 rotor, and now the 5 rotor. All components to build these engines are available in NZ. Keep up the great content! Love it.

[@KyleMohanRacing]

@@jaredrule1431 Yep. We import them. But most don't go short 20b when you can go OEM 20b or 4 Rotor. Why build a 3 Rotor with less strength. Has to be a specific project or reason.

[@hobbawobba]

Short crank 3 rotors do the job well, and cost less than OEM. Plus most of the old OEM 20b shafts need straightening these days. Some of the plates aren't in too flash a shape also aye Jeff Bruce has been making the aftermarket shafts since aaaaages ago

Appreciate the video, you helped to answer a good number of questions.

[@andreasmagiatis4735]

Can you combine the 20B center plate and e-shaft with MSP side plates to build a 3 rotor rx8 engine??????

[@Johnny_OSG]

I think you'd need a custom thick plate due to side exhaust ports. But there was an engine just like that - in the Furai by Mazdatrix

[@spoonsarefun]

Theoretically...this could be done with rx8 the make a rx8 20b hybrid???

[@KyleMohanRacing]

@spoonsarefun not really. You would use a aftermarket 3 rotor crank. The short one to eliminate the thick plate. Then you could do it
