Stuck on a bolt - any ideas?

[Clinical]

Anyone have any tricks/methods they use for shit like this?

I've gone from the engine bay, under the car with standard wrenches / socket wrenches and a ratchet end wrench and simply theres no room anywhere I go to move a wrench.

I'm trying to get my o2 housing off without dropping the turbo.

Heres a couple pictures of the bolt I'm working with.
One from the engine bay with the bolt circled and another from underneath the car with the bolt circled.

Thanks for any help!

Take the turbo off.

x2 on turbo..it maybe takes 5 minutes to drop a turbo

Never mind - got it with an extension + simply taking off the alt belt and sliding the alternator down.

Only reason I don't want to drop the turbo is myself being worried about breaking them bolts off again.. although I used anti-seize and torqued them to specs I'm just paranoid.

Its all off now though :)
