what is the closest i should put my 02 sensor to the downpipe? im going to run my exhaust out the front driver bumper and im going to be using a 16" resonator which would mean my 02 sensor would be like 8" from the turbo. is this ok or not? im pretty sure i read somewhere that the sensor needs to be at least 12" inches from the turbo. let me know

 

good Q

 

you can put it anywhere, even right after the turbo,

 

uhhh, are you sure about right after the turbo? wont the heat like melt it or something?

 

yup i'm sure, my friends o2 was right inside the downpipe flange inside the turbo and never had a problem

 

wow, ok thanks

 

dsm's come stock with the o2 housing bolted to the turbo with the o2 sensor in it maybe a few inches away from the turbo. Of course nobody ever said they were reliable. I don't think they have any problems burning up o2 sensors though.

 

mines is right after the downpipe. Whats the difference from right after the turbo and right before the cat converter?

 

There has to be at least some time lag difference between the two locations. Even if its only milliseconds. However I have mine in the stock location. Lots of space and easily access to the wire harness.
