What is the real issue of mounting the O2 sensor too close to the turbo outlet? Is it too hot there which destroys the sensor or is it a gas turbulence issue?
What is the perfect place for the install of the sensor as there is only about 4-6 inches of space between the turbo outlet and the inlet to the muffler on most set-ups that I have seen.
I would think that O2 sensors can take lots of exhaust temperature as the latest push in cars is moving the catalyst and thus the primary O2 sensor as close to the exhaut ports in the cylinder head as possible for quick lightoff. This raises the temps that the O2 sensor sees similar to what placing it near the turbo outlet would do.
