Sorry Tony, I know the turbo stuff is frustrating. A lot more to deal with and go wrong. There are advantages obviously but I know most road racers prefer NA for reliability/simplicity. I think you've just had some bad luck though..... this isn't the norm. I've run 7 track days now on my setup with no issues (knock on wood) other than a cooling system that is just borderline cutting it.

If I was in your position, I would get a NEW oil hose and a new turbo. Probably a dom 1.5 or a 16g or 18g depending on how much power you want.

Remind me: Is your engine new or used as from the donor? Same question about the turbo.
