That's not a terribly relevant "if...then" comparison. We have no idea how fragile or strong the FA20 is. We can run some calculator numbers and make educated guesses what the typical safe boost level limit is, however that makes no regard for actual individual component strength, which is very much decided on a per-engine design basis. Saying "just cuz BMW can do it" has no bearing on if this particular engine can. Only time and experimentation [or very advanced simulation] will tell.
