How do you figure? only difference between the two motors is the dish in the pistons, same rods, same crank, different pistons and different heads. the pistons are the same strangth and the heads just have a different chamber. So basically the same engine but wrx's have a higher compression ratio so in turn can make a bit more power.
I'm running 420whp/430wtq on stock internals on an sti, no problems yet and its 50,000 miles strong.

Your tanny is getting close to failure at that power if you do not drive it properly.
