I recently inherited my uncles original owner 2001 Oldsmobile Aurora with the 4.0. It's all stock and we had plans to try to built it up to 300hp-340hp. He since passed and I am looking to learn. What would you guys recommend? He was going to throw a turbo on it until he looked at the compression rating on the engine.
