Where should i mount my o2 sensors in a single turbo setuo?

Hey guys could i get some input on where to put my o2 sensors in my setup?. The passenger side is easy but the drivers side i just don't know what to do. Ive seen others do it pre and post turbo, any help is greatly appreciatedAttachment 8447

Anyone?

If there's room right after the manifold and just before the turbo that should work.
Try to find a spot that will allow the engine to have a true left and right bank.
I think the driver side doesn't have the turbo. Right. That o2 goes a just after the manifold about 4-8" on the tube.

Thanks again man! Ya single turbo on passenger side.
