I bought my current 2017 WRX
I bought my current 2017 WRX because of the issues with the EJ257. After what they pulled with the RA motor telling everyone it was the fix for the EJ257 problems. Then when someone ordered a brand new RA long block and and measures and compared all the part that Subaru claimed they had, and that the new parts were much stronger. Everything was the exact same, and the parts were still cast, not forged. Subaru never addressed this when they were called out for it. They could have easily fixed the issues with their rings going out, then of course the piston and rod followed. The reason their rings were failing is because the oil pump wasn't flowing enough oil to protect the rings up to red line. Essentially starving the motor for oil at higher RPM's.
