so you are boring the block out to get more capacity and fitting bigger pistons. You sound crazy, you are going to spend a hell of a lot of cash for a 1.6 to be changed into a 1.8 effectively. The 1.8 already exists why not use that. SOund like you have more money than sense to me. you say you want a nice strong engine yet you are taking a stock engine and modifying it so its very close to the maximum tolerances so therefore not beign as strong as it could
