E99 turbo into OBS
 

My turbo was in obvious need of a rebuild, so I ordered a kit. When disassembling the turbo I found a dinged-up compressor wheel AND a dinged-up turbine wheel. (I know what caused this and don't need any speculation as to that). Now I need a different turbo because the turbine wheel is pressed onto the shaft and cannot be easily had or replaced... correct? I can buy an early 99 turbo for a great price, but I know the exhaust side is smaller. Will the shaft and corresponding exhaust wheel fit into by OBS case with the larger 1.15 exhaust side?
