Here is a company that sells a turbo oil scavenge pump. http://westech.home.mindspring.com/   
 
Thanks, but as it turns out, I already bought one from Buly.  His is a bit smaller and lighter, but higher flow and (unfortunately) current draw.  I always take these specs with a grain of salt though, so we'll see how it works in reality.
 
I've already thought of one problem, which is what will happen if the motor ever stops running.  If that happens, depending on the flow resistance of the stopped pump, it could blow the turbo seal instantly.  The plan will be to route a normal oil drain line to the front cover, which will be about 12" uphill.  Near the turbo, I'll T into the line, and attach the pump, which will send the oil to anywhere convenient. This will also keep the pump from creating a suction on the turbo bearings.  
 
Yep, I guess this makes Rev-5 official, though I'm planning to (try to) hold off until get the Kolb ready to fly.
 
Cheers,
Rusty
