The Honda Civic Type R (EK9) has a naturally aspirated four cylinders in line transverse front engine providing a maximum torque of 160 Nm available from 7500 rpm and a maximum power outpup of 185 PS available at 8200 rpm transmitted to the 15 inch front wheels by a manual 5 speed gearbox.The Honda EK9 Civic Type R Manual! depending on your climate, the best oil for the b16b will be the following: 20 W - 40 - Recommended for climates -10 C to 15 C. 20 W - 50 - Recommended for climates between -10 C to 40 C +. 5 W - 40 - Recommended for climates between: -30 C or less to 40 C +. The EK9 Civic Type R was preceded by two previous generations of unofficial Type R's - the EF9 SiR I and EG6 SiR II. The EF9 was the first ever Civic to be bestowed with the 'Racing' moniker, in the form of the top of the line SiR trim featuring state-of-the-art racing technology available in a production car. K-series swaps are now all the rage in Japan, almost becoming a standard for any fully-built Honda, but Yasu went a different route and stuck with the factory B16B EK9 engine. What he would do was put a big turbo on it, using mostly products from the USDM market, and redo the engine bay to make it as clean as possible.
