BP

The 1,839 cc BP, featuring a bore x stroke of 83 mm × 85 mm, is a DOHC 4 valves per cylinder variant of the B8. This Inline-four 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.

Used in the Protegé, Miata and 323
