I believe whatever comes after the B is the number of .5L cylinders.

B38 = 1.5L 3cyl Gas
B37 = 1.5L 3cyl Diesel
B48 = 2.0L 4cyl Gas
B47 = 2.0L 4cyl Diesel
B58 = 3.0L 6cyl Gas
B57 = 3.0L 6cyl Diesel

Now obviously the B58/B57 don't follow these guidelines. So either they just skipped using the B68/B67 monikers, or maybe the N55 replacement code has been reported incorrectly.
