    It it smokes when you LIFT throttle it is:
    Valve stem seals
    Blow by from the oil control rings.

    what Piston rings did you use, what was the ring gap?

    valve stem seals will smoke slightly at idle, and let a *puff* of smoke out upon initial increase in rpms. They will not smoke at heavy boost when you lift the throttle (Inless they are so bad that there is heavy smoke pouring out at idle)

    I would at least pull the cold pipe to check for excess oil. That would rule out the turbo seals/oil return line problem.

    How is your PCV system setup? Are your PCV valves stock/in good shape?
