Is it actually from the engine or more like in-dash? First thought would
be air in the cooling system. Tends to cause gurgling in the heater core
especially on corners. Try parking it nose up on a *really* steep slope
and bleeding it. Quick, easy and free if it works!

No idea on the turbo. If it was my old Saab I'd guess an airleak somewhere
though. Cheers
