20V Turbo in 4000Q?

[christopher_bender@fmc.com (CHRISTOPHER BENDER)]

     Hey gang,
     
     With the recent mention of putting a turbo motor in a 4000Q, I wonder 
     if anyone has put a 20V turbo in a 4000Q?
     
     I'm sure it would physically fit, as the late model UrQs came with 
     this engine, but has anyone actually done it?  Maybe the nit picky 
     things associated with this job are too much hassle?
     
     Or is simply cost and availability of such a motor a key issue?  There 
     are surely far fewer of these engines out there than the 10Vs.
     
     I'd love to hear any stories...
