I know how you feel man, I went through all of this as well. I know that gut feeling you get when you hear that sound and you KNOW that something is wrong. My turbo by the end of the run (45miles) was making less than 1.5psi of boost at WOT. That really really sucks man. I would tell you to get ahold of Russ, but I think he is on vacation now. FYI a new center section from him, all balanced up, cost me around $380. Hopefully your housings are both still good.
I feel for you man. Make sure you clean out that galley that suv7734 showed, thats what caused my turbo to go (engine sludge).
