I am wanting to increase the power and upgrade to a bigger turbo. My goal is 500+. I know it isn't possible with stock internals. I've been doing some research on what I should replace internally with the engine, and most everyone says to upgrade the rods because they like to bend at around 350+. But what else do I need to upgrade? Can the stock pistons, caps, bearings, hardware etc. hold 500hp+?
