BP ENGINE

The 1,839 cc or 1.8 BP is a DOHC (dual-overhead camshaft) variant of the B8, featuring an 83 mm bore and 85 mm stroke and four valves per cylinder. This engine was called ‘BP-ZE by Mazda engineers’ and featured a forged crankshaft, piston oil squirters, a structural aluminium oil pan with cooling fins, a 7,000 rpm redline, and Variable Intertia Charging System VICS which is activated by a control solenoid at high rpm to increase horsepower in the upper rev range. The engine in base form on 91RON fuel produces 96 kW (129 hp) at 6,000 rpm and 165 N⋅m (122 lb⋅ft) at 4,000 rpm.
