Legacy Turbo 1991-1994 EJ22
K601M975 = 0.020 over, 97.5 bore, 8.5 cr

so stock CR is 8.0:1 and with the dohc heads it goes down to 7.5:1 right?
so with the wiseco it will go from 8.5:1 down to 8.0:1 with the dohc heads?

Well if the over the shelf Wiseco pistons don't work, I think they can make you custom ones. I would suggest contacting Wiseco directly. I'm sure they would be able to help you confirm the numbers.
