13B Rotary Engine (updated 10-19-10)
I purchased a 13B-REW rotary engine a few years back. I purchased a custom made intake manifold for a normally aspirated fuel injected engine. The tubular mount,  bed plate and re-drive support were purchased from the Cozy Girrls.  The RD-1B gear drive unit I purchased from  Real World Solutions. 

INTAKE MANIFOLD - This is a custom made intake manifold for the 13B Rotary Engine. The idea here is to get the air/fuel mixture process on the cool side of the engine. This configuration also keeps a very low profile to keep the engine configuration nice and tight. The intake manifold with a 10 inch runner from the fuel injectors to the intake ports for a tuned port injection.

This engine was rebuilt by Banzai Racing in Indiana and is recommended by Tracy Crook of Real World Solutions.
