It is rumored that this figure was produced at the drive wheels, as this engine was suspected to be under-rated. However Mazda had only ever quoted these figures as SAE Net and DIN which are crankshaft rating standards, as required by law in the countries where the cars were sold. Due to the increased torque output, Mazda was forced to increase the strength of the transmission for the F2T, producing the H-type, the strongest FWD gearbox Mazda produced at the time.

  • 2008–present Mazda3
  • 2008–present Mazda6

Later engines with 'F' nomenclature

The FS and FP are structurally different than the original F-blocks with much smaller bore spacing, much shorter deck height and smaller head and journal dimensions. The FS and FP are more closely related to the Mazda BP engine than they are with the original F-engine.

FS

The 2.0 L (1991 cm3) FS has an 83 mm bore and 92 mm stroke and produces 130 hp and (97 kW) and 135 ft·lbf (183 N·m) in its most common variant up to 170 hp 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 higher-performance 170 hp version, known as the FS-ZE. Mazdaspeed decided to turbocharge the regular FS-DE, as the FS-DET in 2003 for the Mazdaspeed Protegé and it generated 170 hp (127 kW) and 160 ft·lbf (217 N·m), the same hp rating as the naturally aspirated JDM 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 onto it.

The updated FS-DE engine did enjoy a few minor technical features, such as:

-Oil Squirters

-VICS (Variable Inertial Charge System) - A system that can vary the volume of the intake manifold resulting in a broader power band. There were known issues with this system, the most noteworthy was a defect which allowed screws that secured the VICS butterfly valves to come loose and end up being sucked into the engine. Some engines had to be replaced entirely due to the extent of the damage caused.

-VTCS (Variable Tumble Control System) - A set of butterflies in the intake manifold that would close to promote low emissions combustion under cold start at low engine speeds. These had a reputation of being noisy at times.

-Windage Tray

FP

The 1.8 L (1839 cm3) FP is a destroked version of the FS, with an 83 mm bore and 85 mm stroke. It produces 122 hp (91 kW) and 120 ft·lbf (163 N·m). This engine is often incorrectly called the F8, which is the earlier destroked engine based on the FE. The FP enjoys a much better power band vs the FS due to slightly different camshafts and a better rod ratio over the regular FS-DE.

The FP is very close to the FS in many ways and shares a large percentage of parts but has its own FP specific block, crank, rods, pistons and timing belt. The pistons for the FS produce a compression ratio of 9.1:1 (USDM) but when FP pistons are used in the FS they yield 9.7:1 compression ratio.
