They have nice horsepower numbers for a non turbo but are really lacking in torque which is what you actually need for a car to accelerate quickly. They have a lot of aftermarket parts and up grades, some of which include exhausts and Cold Air intakes and while these will add a little bit of horsepower they wont add much.
Honda engines have always been good to actually mod such as decking the head, 5 angle valve jobs and the like, plus if you have the money they are great to turbo.
