The factory's primitive O2 feedback system had the sensor prior to the turbocharger, but that doesn't automatically make it the correct position.

A wideband Lambda sensor should be after the turbocharger, prior to the muffler canister. It should be 15deg higher than horizontal, anywhere in that 150deg arc, but the most common placement is angled aft and at a 45deg angle.

Heat sink -- sure, and additional heat sleeving over the wiring doesn't hurt, either. Furthermore, make some sort of standoff to keep the wires from possibly contacting the turbine housing.
