  I've always wondered but just haven't ask...Can a P-Ported engine also
be turbo charged.  Is there any advantages or disadvantages?

Thanks

Anything you can do in a turbo engine to reduce the pressure losses
in the intake system will help. There is no beating a p-port for low
pressure losses. Integrating the inter cooler into the system will
also help. Take a look at BMW Mini Cooper with supercharger.
