This has to be one of the most reliable M engines ever made...

Do some reading; apparently some N/A stock cars have had spun bearings. People now all think they're doomed
Remember folks, this forum is a VERY smal sliver of M3 population and no one comes onto a forum stating, "hey my car runs great!", it's always only the negative things. That being said, I still don't think this warrants any kind of concern ala S54 and e46 m3 bearing issues.
And yes, I do believe a SC sped up or was def a contributing factor to a failure. Anyone who says otherwise is straight foolish. You're creating much greated cylinder pressures in positive displacement. this car was never intended being a High compression motor for boost.
