If you ordered a new EJ257 from the dealer, I was told they get whatever is the latest the factory is making. So if you ordered a 2010 EJ257, your going to get a 2012 EJ257. Which has the same crank.
174,000+ miles, 5/20/12 new ej257 short block, 8/20/11 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. Also CHECK YOUR OIL, these cars use it.
