Mazda B Engine - BPD

BPD

The mazda BPD engine (also commonly referred to as a BP2) was a revamp of the original BP engine (sometimes called BP1 for clarity's sake). It featured a larger crank nose, larger piston oil squirters, a main bearing support plate, better flowing inlet and exhaust ports. This was also the base engine for the Mazda Familia GT-R and GT-Ae. It is commonly known as the 'big turbo' variant as it utilised a much larger IHI RHF6CB watercooled turbocharger(vj23). The BPD was used as the basis for the engine, with changes such as sodium filled exhaust valves, larger (and front-mounted) intercooler, larger (440 cc) low impedance fuel injectors and stronger engine internals helping to up the performance of the engine to produce 209 hp (156 kW) and 184 lb·ft (255 N·m). The VICS system of the N/A BP has been removed, as well as the boost cut from the ecu. This engine was designed to power Mazda to a world rally championship win, and was thus used in the limited production Mazda Familia GT-R (2,200 built) and GTAe (300 built).
