Here's my guess (not that anyone asked ): Inside the turbine housing, there's a thin divider that goes between the two exhaust chambers. My decision to abandon the Mazda turbo was based on disassembling a use turbo (not the one I was flying), and finding severe cracks in this divider. Some of them were getting close to losing pieces of the divider, which could be what happened to John. If a piece of this breaks loose, it will impact the turbine, and potentially break the shaft. Keep in mind that this is just a SWAG. For the record, I have offered to sell mine to John, but I'll be just as happy to sell it on Ebay. Since I wouldn't personally continue flying the stock turbo, I certainly wouldn't encourage anyone else to do it either.
