[Diy_efi] turbo "throttling"

[Dan D'Andrea]

Erik,

It is my understanding that "divided housing" means just that, a divided 
housing, not simply a divided entry.  I feel quite confident that using the 
divided turbine housing and a throttle body to control whether the exhaust 
gas goes through one or both of the sides of the housing would indeed allow 
you to vary the AR.
