Trying to get o2 housing off without dropping turbo

[Clinical]

Okay so I'm completely trumped by this damned bolt

I have every other bolt off - 2 out of the other 3 have also been a pain but mainly because it was a slow painful process.

However I'm down to the last one and it's the absolute worst...

I have NO idea how to get it off - I've tried going from every angle and even spent $15 on one of those ratchet end wrenches and there just isn't enough room to even get the end over it.

I can get a regular 14mm wrench over it but theres no room to move the wrench and I can(barely) get a 14mm socket over it but again - no room to move my socket wrench.

I'm trying to get my o2 housing off so I can get rid my setup where my wastegate dumps right into the o2 housing, choking a bit of power.

I've gotten under the car and tried from the engine bay and I simply am out of ideas.

Hoping someone has a secret trick or something that will work for this:
Here are some pictures of what i'm working with

First one is just to show the side of my motor and what kind of stuff is in my way.

Third is from beneath the car, the bolt is circled - showing again what im working with room wise

I'm greatful for ANY help, this is driving me nuts.

I had the same problem ... Take off the dp you might be able to get it , I wasn't so lucky as my dp and 02 housing are all one piece and I couldnt get a wrench in there for the life of me so pulling the turbo was the fastest easiest way

yep my dp is already off if you can see in the last pic.

If it ends up that I have to drop the turbo I'm just going to say f*** it and leave it the way it is

I got that off with a long extention. That or use a wobble socket.

I'll attempt some more then although I did try a long extension - I know there has to be a way.

I stand to gain about 10hp from this as the way it was dumped into the exhaust by the previous owner choked it but he just wanted to get it quieter the easiest way - I'm going more for power as it isnt my DD.

Removed the alt belt and pushed my alternator way down and wahlah - my extension and socket fit so perfectly snug that when the bolt was out i had to put it back in because I couldnt get my extension out it was pressing against the bay behind where the alt is haha - so I had to take out my other bolts in the o2 housing and flip it down sideways and then go in without an extension to finish it

thanks all!

Glad you got it out!

I just took mine off today and its is such a pain in the a$$, I left my down pipe connected and took my exhaust manifold off and that made it alot easier. Dont know if that helps.
