Picture below shows the followings:
1. Remaining two bolts that must be removed.
2. Coolant pipe on turbo (disconnected coolant return hose - not shown. Be sure to cap this hose to minimize coolant loss).
Once you have disconnected the coolant return hose, you should be able to lift the turbo and disconnect it from uppipe flange.
Before you do this step, make sure coolant hose to turbo is also disconnected (circled in RED below). You may lose some coolant so be sure to seal it up.
Black hose shown in the center is oil outlet hose, which connects to the oil outlet hard pipe on the turbo (notice squeeze clip on the hose)
