TO me it sounds like a blown head gasket. The crap out the pipe, hows it smell? Sweet at all? Bunch of, or some white smoke?
Seriously though don't drive it anymore and don't throw anymore parts $$$ at it.
Head gaskets can fail, especially if the boost has been fiddled with, etc. Not often but the symptoms you describe sound a lot like a head gasket. It's not a death sentence if it is, I've blown them before and it's a PITA, but so long as you get it handled there's no certainty of damage beyond the head gasket. Just messy.
