honestly, if you had a second car I'd just throw forged slugs in this one and call it a day. The main difference between the 255 and 257 is the variable valve timing on both cams with the 257 vs just the one cam (intake?) on the 255.
but crack this bitch, put in forged pistons, and call it a day. I'm not convinced the STI crank offers anything over the 255 crank, and the Subaru short block still has shitty hypereutectic pistons.
