The Type R has the same 2.0L DOHC I-VTEC engine as powered in the Integra IS model. New engine series DOHC i-VTEC of Honda is intelligent engine which raises torque, mpg, and releases low emission exhaust gas. However, certain components such as the cylinder heads have been exclusively designed for this version of the Type R. Honda has paid special attention to the casting process for these parts that gives a
big improvement in the efficiency of intake and exhaust cycles. The extra efficiency has meant a more aerodynamic effect in the overall combustion process and thus a dramatic improvement in the engine power output and performance of the Type R.
