maybe the turbo wasn't the issue... can you turn the engine by hand?

What does it do when you try to start? Was there proper oil level in the engine before the swap? Any codes? Starter work? Battery good?

First thing that needs done is to see if the engine can be turned by the crankshaft bolt. It shouldn't require a lot of force and should turn freely. If not, then you may have an issue with hydralock. If your turbo intake seal was bad, and allowed oil to be pumped into the cylinders enough to have the top of the cylinders filled, it would not allow the pistons to move all the way up because of the hydraulic pressure of the oil in the cylinders with the valves closed. You might also just try removing the coils and spark plugs and see if it turns freely. If you have excessive oil in the cylinders, you can layer absorbent material over the cylinders and spin the engine over until it blows it out. It could get messy, so this may require a lot of cleanup.

Start by pulling the plugs and taking a peek inside.
When you push the start button, do you even hear the starter engage? You should hear the starter gear pop out and clunk against the (presumably) non-moveable flywheel.

Are you turning by hand with the spark plugs out? If the spark plugs are still in you won’t be able to turn by hand on a compression stroke.

You might have some metal debris in the cylinder if something came through the turbo impeller or if something came apart in the turbo and was blown into the engine. Get yourself a little endoscope cam for your phone and peek through the spark plug holes.

Unfortunately that sounds like something in the engine is in pretty bad shape. Could be debris, a damaged piston ring, etc. Something (likely metal) is probably physically interfering with the travel. Based on what you observed with the turbo, I think it is very likely that foreign matter was sucked into the turbo or the turbo broke internally. Did you inspect the turbo at all?

If it won't rotate a full revolution, you probably have debris from the turbo holding an intake valve open. It can happen when the turbo fails and allows the vanes to make contact with the housing, breaking them off to be sucked into the intake port. The debris could jam between the valve and valve seat, causing the valve to hang open and to make contact with the top of the piston. If this is what has happened, you most likely have a damaged valve, piston, or more. Good news is it's repairable if the piston isn't marred badly and the cylinder isn't scored. Remove the head , have it reconditioned/rebuilt at a good machine shop and reinstall.
