Like it has been said, it is bored out. All EJ motors were oversquare. The FA20 is square and has a longer stroke at 86mm than the EJ's before. The FA24 is already in production and is oversquare by adding bore size, which is probably all they could do because the motor is already wide enough, and the spark plugs are a bitch to change. They would need a wider chassis to increase the stroke.
