Modifying the intake barely bumps horsepower as well as excaust. Turboing a stock motor is bad because youl ruin the engine. If you want a more powerful teg then either rebiuld engine with performance parts or put a diferent engine in to it. I would advise you to keep it stock. These cars are awesome stock and any slight mod will ruin it:cry: These cars are better ofroad than onroad. :lol:
