From my experience a properly built turbo motor should not "burn" oil in the sense that it is consumed internally either through poor ring sealing or valve guides when driving under moderate conditions. With that said, losing 1/4-1/2qt in 5K miles would be acceptable to me.
There are several scenario's where improper PCV can cause oil to leave the motor. This is especially true on high boost/high hp motors. Therefore, I would recommend you verify proper crankcase ventilation before focusing on the motor as the source for oil consumption.
I am not a fan of VTA on the crankcase so using the turbo inlet to help offset block pressure is an effective method for most street applications. I would use some type of sealed/baffled catch can that will not allow oil to get sucked into the turbo, which will consume oil. Some of the turbo mustang guys use belt driven vacuum pumps on the block for this purpose. Also, I have always retained the factory PCV with check valve on the intake manifold for off boost PCV.

I do agree that they really shouldnt burn much oil while driving under moderate conditions...
(BTW I will take the time to read the thread after)
