Question 2 Rotary Engines in one?

I was wondering, would it be possible to combine to rotary motors? And if it is where could you buy a custom crankshaft for it? That would be bad *** if you could, because i have to rotary engines and nothing to do with one of them. So if there is a site that shows or or sells crankshafts, please let me know thanks!

That would be a 26B and you would need a custom E-shaft for that (there are no crank shafts in a rotary engine).

And this really is not a 2nd gen topic

A shop would have to custom build it for you. Mazda built a 26B for racing, but never made it available for production cars.

Man that sucks....how in the world could i do that? IT would be so bad *** to have a four rotor engine, but of course if it was that easy everyone would have one.

....But it can be done! At least in an FD. I've never seen a 4 rotor in an FC.

Granny's has a very informative article about their 4-rotor outlaw racer at
http://members.tripod.com/~grannys/4rotor.html
This guy has a link about a homebrew 4-rotor used in tractor-pulling events, it uses motorcycle chain gears or an automatic torque convertor to join the engines.
