Mazda Miata BP18 Performance Engine Parts

Mazda BP18 Performance Parts

The 1,839 cc or 1.8 BP is a DOHC (double-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 Inertia Charging System VICS which is activated by a control solenoid at high rpm to increase horsepower in the upper rev range. The engine is a favorite for both N/A and turbo motoring enthusiasts for its robust design, materials and construction.
