Where should i put the o2 sensors? How far away from the turbo?

I have mine about 3 inches from the turbo at a 30 degree angle (30 degrees up from horizontal) and it works great

I was wondering on my lt1 if i should have the stock O2 sensors in the crossover or in the downpipe. And if they must be in teh downpipe is there anyway I could possibly have one o2 run both banks?

I know there is not a lot of support here for the LT1, but this would help in my build

Ok your talking about stock o2 sensors, I thought you were talking about a wideband.

I'm not sure if the PCM will run both inputs off one sensor. Thats something for the LT1 section probably.

But when you get yourself a Wideband you will want it in your downpipe semi close to the turbo, I've been told 3-6 inches is a good range, you also have to have it at a good angle.

As far as the stock o2 sensors, I don't know that it matters too much but I would put them in the downpipe if you can.

no put the narrow band o2's as close to the collector as possible.
wideband about 3-6 inches fromt he turbo as stated above.

Ok... I did hear that the pressure and temp does seem to take its toll on the o2's though...

Any input on this?

Thanks for your help.

ive heard the wideband cant take the pressure and temps before the turbo.
but most factory o2's do go before the turbo, near the collectors.
