You can't stay with stock pistons to reach what you are trying for. The stock pistons are much weaker than the stock rods, and it is a waste of money to upgrade the rods and stay with the stock cast pistons. You could use stock rods and forged pistons, or upgrade both, but the pistons are the weak point in almost every Subaru motor ever built when you add boost.
