For anyone wondering what the "New part number" crank and oil pump I used. These are supposedly the latest part number from Subaru for the next year STi. The part numbers have changed for both the crank and the oil pump. Visually they don't look any different from previous non-nitrated cranks, but according to Subaru it is the latest and greatest. I didn't do any heavy digging into this, I just like to run the latest part number when doing my builds regardless of any revisions they have done. Its new? Great I want it.
