Mazda B Engine - BP

BP

The 1,839 cc or 1.8 BP is a DOHC (dual-overhead camshaft) variant of the B8, featuring a 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 aluminum 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 at 6,000 rpm and 165 Nm at 4,000 rpm. The engine is a favourite for both N/A and turbo motoring enthusiasts for its robust design, materials and construction. This particular variant can be found in the following vehicles:

• 1989-1994 Mazda Familia GT (European & Australian Market)
