I think Smaay just rounded down to provide some basic ball park number. You cant pinpoint a specific horsepower number to each piston or a certain psi. It all depends on what turbo you use, how well you tune the car, and the current condition of the motor. Its silly to argue about minor details with stuff like this.

Neil_Y, no you dont need to upgrade the pistons or anything internal on the engine, however its a good idea to see what kind of shape your motor is in. If you have a lot of miles on it, or if its currently burning oil or has any other issues, it might be a good idea to rebuild it or swap for another engine thats in better shape.
