I m not saying that they dont make no power. I have researched and that is why I think that the turbo is better. I have a couple of friends with stangs totally dif car than a civ. But one has a vortec and one has a turbo and that seems like the way to go the are both fast on stock internals. I know that cars are huff'en that make good power. It just seems like turbos are cheaper and more reliable
