[QUOTE="mox69, post: 1212528, member: 76391"] The main thing I would be worried about is the rings. They rub more on the cylinder walls than the piston does.. A forged piston is just a "tougher/harder" (unscientific i know) metal, it can take more of a beating. I am unsure if it expands differently than a stock piston when heated. I assume if any, not much. If you are concerned about the piston rubbing, make sure you measure it before it goes in. Also, I believe some companies make pistons with anti-friction coatings. They have a black coating all over the piston. Wiseco makes a good product, I wouldn't worry too much about using their stuff over stock in just about every situation. [/QUOTE]
