Hi Ed,
Thanks for providing the data on Subaru's attempt to get 2.5L performance from a 2.0L block. I should have qualified my statement to say that it is RARE to find 10:1 compression on a turbo Subaru engine.
Some CR data below:
EJ205: 8.5:1; EJ207: 8:1; EJ20TT: 8.75:1; EJ22: 9.5:1; EJ222: 10:1; EJ226 8:1; EJ25 (n/a) 9.5:1; EJ255 8.4:1; EJ257 8.7:1
My main objection is your statement above: "literally any junkyard Subaru mill you can find comes with a static CR at 10 or above", which is hyperbole on your part and just not true.
