According to Eric Hsu, founder of XS Engineering and current Cosworth engineer, despite some setbacks, Cosworth will be releasing its bolt-on supercharger soon. The setup produces approximately 210 hp at the wheels, looks OEM clean and is designed to be legal in all 50 states. But Cosworth isn't stopping there. Hsu says that a Stage 2 version is planned that ups the boost, adds a set of headers and includes some hotter cams. We can't wait to check it out, particularly with the "1G" suspension package offered by Mazdaspeed.
