Sorry for this question but i need a proper answer and i seem to find a different amount of answers...what is the stock compression ratio on a EJ 205...because i am ordering pistons tomorrow and i need to know what ratio to choose
Because 8.0:1 and 8.2:1 are really friggin' low. Look, turbos love low compression it's true but more compression does help. You want to find a middle ground that allows for full use of the turbo's efficiency range and utilization of as much of the air as possible. By modern tuning standards, Subaru's compression is on the low side even for a turbo car.
