Every week you can find a new teardown of some abused, misused and/or poorly designed engine. I've got over 150 videos of failed engine teardowns on this channel. This week's teardown is a BMW S550B30 from a 2015 or 2016 BMW M3. This engine can also be found in the M4, and the M2 competition. This is a 3.0L, Twin turbo, all aluminum, DOHC direct injected inline 6 with valvetronic. These engines have several different power output levels but this one likely was the 425HP found in the non comp M3 and M4. They can make as much as nearly 500hp in factory trim. This particular engine seems to have a pretty interesting past. I wish these engines could talk because I'm sure this one would have a wild story about its life as there are several questionable things going on here. These engines are NOT cheap and I think several bad decisions were made along the way that ultimately ended in someone paying a rather large bill. Let me know what you think this poor engine went through. Why am I doing this? My name is Eric and I own and run a full service auto salvage business called Importapart. Part of our model includes dismantling core and blown engines to salvage and resell the good parts. We do not rebuild engines, we merely sell parts to those who do! I really. hope you enjoyed this video. As always, I love all of the comments, feedback and even the criticism. Catch you on the next one! -Eric
