The O2 sensor can take a fair amount of heat, but as someone said, if you're concerned, make a heat sink. In a Bosch article I read a couple of years ago, an O2 sensor really doesn't start working well until exhaust gas temps hit 1000 degrees (heated units help get the temps up early for accurate readings). The heat from the turbo doesn't even get hot enough to burn the shrink wrap on the wiring, which is closer to the turbo than the actual unit.
