A lot of good info here. And great civilized argument about M54 vs S54.
Thanks for sharing your experiences.
The only misleading part from bigjae could be the way he describes the failures. It was the lubrication system that killed both engines not the FI. But I understand the issues with FI MS54.
So don't get me wrong I actually agree with bigjae that S54 is better racing platform. Heck, BMW didn't design it that way. Also from my own experience I see the M54 better street car (the powerband of supercharged 330 is way more street friendly)
