Makes me feel happy in my special place.

Where the hell did they get a 4-rotor engine?
- Goodspeed - 09-16-2007
That sounds amazing...I'm pretty sure you can build a 4 rotor, I'm not sure if its either two 13B two rotors mated together or a 3 rotor Cosmo with an extra rotor but man...that car is rediculous

You used to be able to buy a crate 4 rotor from Mazdaspeed, I think, but at the very least they used a 700hp n/a 4 Rotor for racing forever.
A four rotor is a little more than "two 13B's slapped together" but the modularity of the wankel makes building a 4 rotor from 2 two-rotors alot easier than building, say, a V8 out of two I-4's.
You could get the 4 rotor eccentric shaft from someplace like this, and then use 13B (or maybe Renesis?) housings and rotors and bolt them all together.
You'd probably make 4-500 horsepower without really trying too hard.
(P.S. Granny's speed shop made a "ghetto" 4 rotor by basically welding two E-Shafts of 13b's together to run in a dirt car, but I can't find the link.)

there is a guy in aussie land campaigning a 4 rotor FD that he put together. it's well up there in power and holds down some pretty amazing times. i think it's one of only a handful, if not the only, 4 rotor FD in australia.

I found that link:

"The engine design uses modified 13B eccentric shafts, and the two engines are joined by a custom made 3/8" thick aluminum adapter plate...By joining the two engines as I did (using only 1/2 the normally required flywheel and counterweight mass), the engine rev'ed much faster than a single engine by its self...In the form shown here, output was around 550hp."
Neat stuff.

son of a bitch! My funny parts are tingling!

This is the car by the way. Looks.....aquatic.

that's so cool...i have to salute guys that create stuff like that on their own time. i don't even want to attempt to think of what a 550 hp 4 rotor does to a car that size!

Separated at birth?

Put that motor in a FD!

yeah, it's ugly as shit, but who cares! :-)
