Ok i am in the mids of getting all my turbo setup together, and i was in class today and we were tlaking about O2 sensors, and i am just wondering for all you guys that have a 2.3/2.4 turbo setup, what did you do with the O2 sensors in the manifold?? or basically what did you do with all your O2 sensors?? If someone could please help me out by answering this it would be really appreciated!

Thanks Jordan

You put them in the exhaust. The one on the manifold you want to have close to the turbo manifold, or I gues the turbo, the rear O2 sensor put close to the same location as it is stock.

So bascially leave the one in the cat or whever it may be and just get an adapter or soemthign to put the one that is usually in the manifold as close as you can get to the turbo, now do you have to get a different O2 sensor like a hotter one or same one will work?

O2 sensor don't come in varieties of temps. That's spark plugs. O2 sensors only come in NARROWBAND and WIDEBAND types.

Ok thanks for the help guys!

Can you use a 4-wire sensor before the CAT so it is self heating and does not need to be so close to the manifold?
