Damn man! That's some shitty luck!
I've got a stock WRX turbo for you if you want it. Probably has about 35,000 miles on it. I'll sell it to ya for $50 if you can't get all this covered by Lithia and decide to stick w/ a stock turbo.
I also have my stock EGT sensor somewhere, but the connector for it is cut off. Nothing the connector from your broken sensor and two good crimp connectors can't fix. That's yours for free if you want it.
My O2 sensors are in a box over at Benson Bros. Racing down in Moundhouse. Once my car's running I need to get it down to them for some fabrication work. I wasn't planning on going down there before then though to get the O2 sensors, but that may be a possibility if you really need 'em.
