Because if you buy a used one that is supposedly in decent shape, you have no idea if there may be a problem with any of the seals (orings and such) until you bolt it on and try it. I have never found one that I've pulled apart that the orings weren't completely hardened from age and heat. Plus you also have the added satisfaction that you know what it looks like inside. Plus you have the reassurance that it will last for quite a while.
I mean, would you buy a low milage engine and just stuff it in your car without at least dropping the oilpan to see if it's ok? If you open it up, you might as well refresh the seals while you're in there. I think any engine rebuilder or car mechanic will back me up on this one. If it's used, make sure it's good enough to last for a while before you bolt it to your car.

I agree with you to some extent. Why would you buy another if you are planning on rebuilding it though? Why not use the one he has?
If I were buying a used engine, the first thing I would do is get a warranty from a junkyard or something. Yeah, I would drop the pan but I wouldn't rebuild it (pull the pistons, replace the rings, do a valve job, etc.) as long as it is out of the car. Why wouldn't I just rebuild the one I have instead of spending money on something I dont need. See my point now? You would just have another lying around. If your plans are to rebuild something and you have one needing a rebuild, why buy another? IMO just a waste of money.
I would stick with the turbo you have. Check it for shaft play and get a used one if nessecary. Dont assume the turbo is burning the oil though. Check the return line gaskets and see if they are leaking. Just a simple look under the car.
