Engine R20A

Engine R20A

This two-liter unit is nothing more than an oversized R18A. The increase in volume from 1.8 liters to 2.0 was achieved thanks to a long-stroke crankshaft. The changes also affected the intake manifold, balancing shafts were installed on the motor. The cylinder head remained with one camshaft, sixteen valves and the iVTEC system. Motor without hydraulic lifters. From the previous version with the K20 index, the motor differs in a more urban character, improved traction at low and medium speeds. The engine has become more economical, reliable and simpler.
