will my stock ls1 o2 sensors survive pre-turbo?

[ryans1000]

Will my stock ls1 o2 sensors survive pre-turbo? I think one of them is acting up already and I've only been running turbo for a couple weeks. However it is an old sensor. I was originally told for accuracy install the o2 two sensors close to the head pre-turbo like the stock locations. Another guy told me that the heat and pressure of a turbo setup will kill the sensors quickly. I have a wideband post turbo. I may just run open loop all the time but not sure if I'll want the narrowbands also.

I have been told that they will not survive Pre-Cat. However I have seen many factory turbo cars with the O2 sensor in the manifold---Pre-Cat. I have mine post cat.

No cat here.

He said cat but he meant turbo.

both mine have been pre-turbo for about a year. one is in the turbo manifold itself.

I wonder if they make different model narrowbands that will work for the ls1 but have higher temperature tolerance. So do narrowbands work the same when they are post turbo, I know my turbo talon had a factory narrowband right after the turbo. But I wonder if the factory computer closed loop operation is different when the o2 sensors are no longer in the same environment (temperature, distance, pressure) ???

BRAIN FART,
I did mean post TURBO.

Turbo Buicks have the NB just under the turbo entry. Some run for yrs that way. Boost from OEM chip setting is about 14# max. Many hi boost, [20+#], applications do not kill the sensor, unless race gas is introduced.

interesting, thank

I thought o2 sensors would get increasingly inaccurate under positive pressure. I never could keep one together on my old 305 turbo conversion, the end of the sensor would just be burnt off lol {stub}
