Turbo six on a Budget

You can certainly do this with stock cast pistons. Many people have. But you know you're gonna want more and more. The cast pistons have their limits.
yes and i want to do it right. Looking over this i kinda see two paths keep the stock internals and get the turbo but keep the boost down or build the engine without the turbo then save for the turbo and add it latter. If i run the turbo stock and risk breaking a piston would the block most likely be done?
