Re: ------- o2 sensors !!!???!!!??? getting to hot and breaking ?
im wondering the same thing, i ran mine about 3 inches from the exhaust turbine for about 30 miles or so and then got paranoid and moved down behind the oil pan about where the stock sensor goes, but i dont know if i damaged it or not when i had it that close and theres no real way to tell without buying another one

Doubt that it's getting too hot, plenty of stock cars have their O2 sensor in the O2 housing right off the turbine and they do fine. I had a stock O2 in my HF mani before the turbo for a couple years with no problems either.

Burning alot of oil? Running leaded gas?
What kind of wideband controller are you using?
It is possible the heating element that lights off the pump inside is getting burned up, but its unlikely. Do you have an EGT gauge and if so what kind of numbers are you seeing in boost?
Those bosch sensors are cheap units. Bosch sells them at $30 a pop. SO they cant be that super-GDM-fantastic.

The Subaru I took a turbo from had the O2 like less than 2 inches from the turbine exit.
Will having an upside down o2 always kill the sensor? If so I gotta move mine.

Problems with it not being 10-2 o'clock is condensation. Your combustion creates mostly water vapor and co2, and water will kill the sensor.
The thing about 'stock' locations - very few of them are WIDEBANDS. Widebands are much more sensitive. I know Innovate recommends using a copper heatsink if you need to put it in a hot spot, but i can't recall the max temp it can take. They usually say 12-18" from the turbo. Having it before the turbo results in bad readings, generally it reads more rich than it really is, since the exhaust is twice as dense at that spot.
