What are you trying to say? Can you not get the nuts and bolts loose? Are the nuts off and the pipe seized to the turbo?

^:facepalm: very helpful.

Have you disconnected the DP from the cat back? Give it a good pry with a nice long handled pry bar.

Make sure absolutely everything connected to the turbo is disconnected.

Its most likely rusted in place from multiple heat cycles and rain water.

actually...one of THE secrets to doing a quick turbo swap is to drop the WHOLE ENTIRE exhaust off in ONE PIECE

taking the exhaust apart is a fools errand and 100% unnecessary

Here's a great tip, if you don't have any idea what the hell you're doing, don't do it.

Did you try trouble shooting or did you just decide it was the turbo for the hell of it? What you're describing could be a ton of things.

And your profile says 2004, but you say 2008. Be prepared to spend money, I see this motor going BOOM soon.

Your research.

What are the mods on the car? Is it tuned?

I can't believe you just dove into a turbo swap without confirming that it's the turbo. Shaft play can be felt just by dropping the downpipe off anyways.

You said the turbo was smoking. Does that mean you saw smoke out the exhaust or smoke was just rising from the turbo itself in the engine bay? What does that mean?? It could be that the dealer diagnosed the problem as the turbo oil seals. Do you see oil in the intercooler or turbine?
