Good for you! Ordinarily turbocharger rebuilding is something I don't touch, as the warranty is something we don't want to deal with, but for a DIY'er it's certainly worth the try.
Please let us know how it works out.
BTW: The turbo on "Rise 'n Shine" is obviously recently changed. Furthermore, when I winterized, I discovered the outlet elbow from the turbo (which goes from the turbocharger to the wet elbow) was completely rotted through, and the wet elbow was only held in place by the exhaust hose. No wonder I smelled exhaust...
