In order to build the best EJ engine, the Tomei R&D engineers focused on a highly responsive and powerful setup that still maintained big torque figures as well. For this objective to become a reality, countless data acquisition and numerous testing was performed on the engine dynamometer. As a result, the response was like having the throttle body directly connected to the right foot, at a non-hesitant linear reaction. With the output numbers at 500 HP and 500 ft-lbs of torque, the hard work put into this setup speaks for itself. This product is a must have for EJ enthusiasts who desire to have an advantage over the rest either on the streets or at the track.
