FS
The 2.0 L (1,991 cc) FS has a bore and stroke of 83 mm × 92 mm (3.27 in × 3.62 in) and produces 130 hp (97 kW; 132 PS) and 135 lb⋅ft (183 N⋅m) in its most common variant up to 170 hp (127 kW; 172 PS) in the Japanese domestic market. In 1998 the engine evolved into the FS-DE by undergoing several changes, most notably a distributorless ignition as well as the move from hydraulic lifters to solid shim-on-bucket lifters. Japan received a couple of variations of the FS motor, all with increased power outputs. The highest being the Mazdaspeed Familia version of the FS-ZE which produced 170 hp (127 kW; 172 PS). Mazdaspeed US decided to turbocharge the US FS-DE, known as the FS-DET in 2003 for the Mazdaspeed Protegé and it generated 170 hp (127 kW; 172 PS) and 160 lb⋅ft (217 N⋅m), the same hp rating as the naturally aspirated Mazdaspeed Familia edition FS-ZE but with a sharper torque curve. This means that the Mazdaspeed Protegé's engine is internally identical to the regular FS-DE, except with a turbocharger installed
