I don't know anybody with 50k on a rebuilt sr20, or even 30k with an aftermarket bearing. Some people rebuild them and just don't drive them much. Many fail without any report; what you see "failures" is only a small fraction of what truly exists (many are too embarrassed) and we have quite a fair number of confirmed failures from folk who weren't too embarrassed.
