Where would a wideband o2 go on a twin turbo setup?
Maybe in the a merge pipe? X or H? Or are two widebands used?

i would say merge , but it would be nice to moniter each bank with 2

Yeah. The merge might be where ppl install theirs.
I'm doin a single turbo build rite now and I'm gonna be installing mine before the Y pipe.
I was just wondering where it would go on a twin setup.

Why not use 8? I'd recommend 1 per bank at a minimum. Don't put it in the merge pipe. Also, don't let the WBO2 tell you what to do. Go by the plugs, and use the WBO2 as a tool to support what the plugs and your trap speed tell you about how the engine is running.
