I was wondering what the changes between the 13B and Renesis engines
were.  Initially I heard that the engine was overall smaller - smaller
rotors, smaller e-shaft, smaller housings, etc. etc.  Now I'm hearing
that the sizes are the same, just some configuration changes.

I know that the exhaust ports are now in the side housings instead of
the peripheral housing.  Apparently the rotors are lighter.  Did any
other engine dimensions change?
        E-shaft eccentricity
        Housing radial dimension
        Rotor radius
        Rotor width

Is there a(ny) link(s) we could check out to compare differences between
the 13B and Renesis?

Thanks in advance,

Its the same basic size and weight. The weight saving they claim comes from
the elimination of the elaborate sequential turbo's on the third gen.
