20c engine
 

who would be interested in a 2l version of the 13b just a scaled up one to 2l and then moded to fit the stock bolt patern for the tranny.
im not yet making it just wondering if anyone would be interested in it. who knows if theres enough interest in it I might just have to get it out there.

Sound like you need to get a prototype up and running to sell the idea? I'll be the 1st to tell that any interest here on this forum will be solely based on seeing an actual prototype.

In the above link, this person built a custom 12 rotor but still used Mazda rotors and dimensions but with his own configuration. Sounds like you wanna build a totally new rotary from scratch? I'm all for it if you can get a prototype up and running. We have yet to see any running videos of the above engine due to the Joplin MO tornado that almost hit his shop last month.
