Yes, I did about 13 months ago.
If you search through some of my old posts you will find lots of info. Some have been able to access it from the passenger side wheel well, but I think that would be very difficult unless you break the turbo/manifold in to two parts before you bring it out (which wouldn't be that big of an issue). I purchased a small lift with the $1000s I saved by doing it myself and accessed it from the rear. The manual says to remove the front subframe, but that is definitely not needed. I removed the driveshaft and exhaust system and both wheel well liners. The hardest part was one of the bolts on the manifold to downpipe but I was able to access it with lots of "wobbler" extensions.
When going back I replaced the turbo, exhaust manifold gaskets, the oil line and water line gaskets, the exhaust manifold bolts (the manual says to replace and they are copper so I have been told they should be) and the exhaust gasket (may not be necessary). It was a royal pita the first time I did it, but if I had it again and I had a second pair of hands while dropping the exhaust and 3 piece driveshaft, it would go much more quickly.
BTW, you can find what appears to be identical turbo replacements for about $1000 or a little less, but I got one with the aftermarket cast iron manifold in hopes that it would last longer (because the manifold is almost always what fails). I got it for about $1000. I think the company just buys the manifold from China (and that manifold was available on ebay, at least at the time, for a about $250). Mine has last a little over a year, but I haven't driven that much in the last year.
