If I place the O2 sensors at cylinders 3 and 5 then the O2 sensors would get readings from cylinders 1+2+3 and 6+5. One from 3 cylinders and the other from 2 cylinders,
better than just 1 cylinder.

The connection pipe for the turbo would probably be between 4+5 or at 5 cylinder on the bottom.

IDK what BPC did. I will have to look closer to their build of their turbo N52.
