I found this for sale on ebay a while back. I have never seen anything like this before, the manifold is odd and its distributed. The oil system isnt stock either, maybe for a sump?

JUst wondering if anyone knows anything about this motor or the setup its using.

 

thats pretty crazy looking, my best guess is its a carburated blow-through turbo setup. but i really have no idea...

maybe post the link to the page, it doesn't say ANYTHING about the motor?

 

I'm pretty sure it has to do with propane.

Edit... This is what Pele said on the same set up..

from thread; "Whats up with this 13b?" https://www.rx7club.com/showthread.p...+with+this+13b

 

wow

 

+1 looks like a gas pressure reg on top of that crazy manifold

 

damn, and what about the hp`s and torque?

 

im guessing its been modified for aviation use.

 

The ebay add didnt say anything just that it was a 13b rotary engine, the propane idea looks probable, I didnt even remember seeing that thread, oops.
