"I have heard with additional work to the engine at the same time boring out the engine, replacing seal on some other stuff you can add another 20-30 hp on top of that. But I also hear the additional work is about another $5,000 on top of having the turbos retrofitted onto the engine."

Just a side note: the boxster engine has Lokasil lined cylinder walls which CANNOT be bored out. The block is slip-cast with two types of aluminum: one which maximizes the block's torsional resistance and one which maximizes the wear properties of the cylinder walls. Therefore you cannot simply widden the cylinders....look it up.
