	Im not so sure about this.  If it was so radically different, how 
come the turbo and NA ports and valves are virtually identical?  The 20v head 
seemed to produce similar reults in both motors also.  You can go ahead and 
hog out your ports since you figure the air is being pushed through, but you 
are going to suffer seriuos lag untill that turbo kicks in.  Im wondering 
what your research said to make you believe they are apples to oranges?
