$2200.00 that's installed? You can get aftermarket turbos with slightly larger intake and exhaust, which would run a little cooler add some horsepower and increase milelage, for $500-600 less then what dealer wants...that's assuming price quoted is for turbo only. But as suggested, if yer handy with tools, its not that difficult a job. On a scale of 1-10 (1 being easy...) I would say a 6. Mostly due to lifting and holding turbo,exhaust manifold in place while installing manifold bolts.
You can pm me for more install info...job is more physical then technical.
