The B58 debuted a few years ago and now gets a new cooling system, head, timing chain, oil pump and a forged crankshaft. The block and air induction system have been modified, and the new high-pressure direct-injection fueling system is rated at 5,076 psi (350 bar), up from 3,626 psi (250 bar).

Are there now different revisions of the B58 from its original debut? Any of the original cars that the original B58 launched with like the M240i getting all this revised kit?
