It is located between the turbo and the block. Picture is my driver side turbo looking forward from the cat. If you have not already removed it, that bolt circled must come out.

it's hard to tell. Is that support attached to the block or the heads? I have a 2011. I need to pull the heads to fix bent valves. I'm hoping not to pull off the turbos. I'm thinking I can remove the three turbos bolts and slide the head up and out. Is there any other connection turbos to heads other than the three bolts?

If my memory is correct, bolt I circled does not go in the head. Besides three fasteners holding turbo to the exhaust manifold, the coolant pipe headed behind the engine terminates in a jiffy fitting screwed into the back of the head. That’s going to have to come apart to leave a turbo bolted on a down pipe. You may change your mind and remove that turbo once you get into it.

Now that your really in there can you help me decide something? I have to remove the heads. I'm down to removing the head bolts. I haven't touched the turbos yet. I'm hoping I can just remove the three hex bolts from the turbos and lift the head away from the turbo. Does it look like I can do that without removing the turbos?

Have not removed a 3.5 head myself.

On my 2011 3.5 eco I pulled the heads without removing the turbos. But you need the unbolt the three turbo to manifold bolts. The water coolant lines behind the head there is a jifi fitting that absolutely needs replaced. It will leak if reused.
I removed the head with the exhaust manifold attached. Everything just slides right past the turbos. Don't reuse the turbo bolts. They are torque to yeald and the gasket is crush. Get new gaskets.
