Glad I have the new EJ257s in my '19 STI

It'll be interesting to see how the better rods in the FA24 hold up in comparison to the FA20. Subaru certainly has the ability to make it stronger than the EJ257, but the question is will they do it?

Of course, then there's the S209's EJ257 with forged internals.. too bad we won't be able to get our hands on those short blocks.
