Paul,

Does a list exist of best practices for replacing an 0320 with a rotary.

There is so much info and different routes to take it is confusing ( for me anyway).

I am building RV 6 wings (emp complete), and want to end up Rotary powered 160-170 hp.

Could you come up with a list?
Vendors included?

Basically you have two choices. P-port or side port.
This applies to the older 13 B or the newere RX8 engines.
You will get about the same power with either engine.


The fuel burn will be roughly the same.

The same goes for carb or efi.

We may not see a 16B for several years.
If it comes out like they project the max RPM will
be less than a 13B or RX8 engine and the power
may be about the same due to this factor.
It is designed to produce more torque at lower
RPM's for car use. The adbvantage will be stock
aluminum end housings which may result in less
weight but not guaranteed as it is a larger engine to
begin with. The fuel burn per HP generated may be less
due to a higher theoretical compression ratio.

I would not wait for it. Get an RX8 engine and p-port
it. You will get 25% more power at all altitudes.
You don't need 250 HP at sea lever but that engine
will give you roughly 175 HP at 12,000 feet.

IMHO airplanes are about freedom to go places.
If it don't do 200 MPH you might as well drive unless
you are in the outback :)
