Mazda F engine
From Wikipedia, the free encyclopedia
The F engine family from Mazda is a straight-4 piston engine. This motor was found in the Mazda B-Series truck and 1984-1992 Mazda 626 families. These are entirely different engines than the Mazda B engine family.

[edit] MA
The 2.0 L (1970 cm³) was designated MA Bore was 80 mm and stroke was 98 mm. This SOHC engine with a 2 barrel carb produced 103 hp (76 kW) and 123 ft·lbf (167 N·m). A more fuel-efficient 1 barrel version produced 90 hp (66 kW). Fuel injection was available in 81-82. Other capacities were available in some markets, such as the F/NA 1.6.
Applications:
- 1981-1982 Mazda Luce/Mazda Cosmo
- 1975-1980 Mazda Luce/929
- 1979-1982 Mazda Capella/626
- 1978-1985 Mazda B2000
- Ford Courier
[edit] F6
The smallest of the second generation of F family engines was the F6, a destroked and debored version of the base FE 2.0. It replaces the F/NA 1.6 from the previous generation. It was an 8-valve SOHC engine with an 81mm bore and 77mm stroke, with a compression ratio of 8.6:1. Output was 73hp (53kW) @ 5500rpm and 89lb/ft (121Nm) @ 3500rpm. Applications:
- 1983-1987 Mazda Capella/626
- 1983-1987 Mazda B-Series
- 1983-1987 Mazda E-Series
[edit] F8
A destroked FE, the F8 had a capacity of 1.8 litres, and came in several configurations including a 12-valve head and fuel injection later in its life. It had a bore of 86mm and a stroke of 77mm, with a compression ratio of 8.6:1. Power output was 80hp (60kW) @ 5500rpm and 98lb/ft (133Nm) @ 2500 for the 8-valve SOHC carburetted versions.
Applications:
- 1983-1991 Mazda Capella/626
- 1985-1987 Mazda B-Series
- 1983-1987 Mazda 929
- 1983-1991 Mazda E-series/Mazda Bongo
[edit] F8-DOHC
The F8-DOHC is a destroked version of the FE-DOHC displacing 1789cc - 1.8L. It shares the common bore of 86mm with other F-blocks and has a shortened stroke of 77mm. It uses the same exhaust cam, but a different intake cam with less lift and a long, single-runner intake manifold. The F8 is usually identified by its unpainted cam cover. Output was 113hp (84kW) @ 6000rpm and 115lb/ft (156nM) @ 5000rpm.
[edit] FE
The 2.0 L (1998 cm³) FE was very different with a square 86 mm bore and stroke. It was an 8-valve SOHC engine for front-wheel drive and rear wheel drive pickup use. Output was 90 hp (66 kW) for the 1 barrel carburetor version, 100 hp (74 kW) @ 5600rpm & 156Nm @ 3700rpm for the 2 barrel carburetor version, or 118 hp (88 kW) @ 5300rpm & 178Nm @ 3700rpm with fuel injection and higher compression (10:1 vs 8.6:1).
Applications:
- 1983-1987 Mazda Capella/626
- 1985-1987 Mazda B-Series
- 1983-1987 Mazda 929
- 1983-1990 Mazda E-series/Mazda Bongo
[edit] FET
The 2.0 L (1998 cm³) Fuel Injected, turbocharged FET version of the FE produced 135 hp (101 kW) and 175 ft·lbf (237 N·m). It was a water cooled 8-valve SOHC engine Featuring a small turbocharger, and no intercooler. The Japanese variant of this engine was dubbed the Magnum Turbo. Given that the peak power for the NA Fuel injected FE is 118hp, the rated power for the FET is said to be conservative.
- Bore x Stroke : 86mm x 86 mm
- SOHC 8-valve
- 7 psi (0.5 bar) stock
- Peak power: ~5250rpm
- Peak Torque: ~2800rpm
- Redline: 6000rpm
Applications:
- 1984-1986 Mazda Capella (Japan)
- Ford Telstar turbo
- 1986-1987 Mazda 626 Turbo
- 1986-1987 Mazda 929 coupe
[edit] FE-DOHC
The FE-DOHC was the DOHC variant of the FE. Commonly called the FE3 because of its head castings, it was used in some 626s from Europe, New Zealand and Japan; but not the U.S. or Australia. However, it is found in the U.S., Australian, and other 1995+ Kia Sportage. It can be fitted with a crankshaft from the F2 or F2T to produce 2.2 L, but requires aftermarket pistons to compensate for the increased stroke. The FE-DOHC is usually identified by a gold cam cover, however this spotting method is not a guarantee. There were at least six different FE-DOHC engines available.
A high-compression variant of the FE3 exists but the only truly distinguishing mark is the domed pistons inside the engine. Factory redline was 7000 rpm but well made examples with aftermarket engine management and better valve springs are seeing continued 8000 rpm usage.
Specifications based on non-cat. version:
Compression: 10.0:1
Bore/Stroke: 86x86
Power: 145.97 hp (108.8 kW) @ 6000rpm & 133ft·lb (182 N·m) @ 4000rpm
The FE-DOHC came in a cat version in 1989, with a lowered compression (9.2:1) and 138hp.
[edit] F2
2.2 L F2 - 2184 cc (86x94 mm) - Stroked SOHC version of the FE. Found in the first-generation Mazda MX-6 and Ford Probe, 1988-1992 Mazda 626, and 1987-1993 B2200.
The B2200 featured the same short block with an 8-valve cylinder head. The valves use dual springs and the rocker arms contain hydraulic lash adjustors (HLAs). Using improper oil, oil filters without drainback valves, and storing the vehicle for more than a week without running may cause the HLAs to tick during startup. This tick should go away once the engine has warmed up if not repairs or other corrective measures may need to be taken. (1991 Mazda Factory Manual & Service Bulletin -- Kyrasis6).
[edit] F2T
The F2T is a turbocharged F2 with 3-valves per cylinder (12 valves total) and an air-to-air intercooler published at 145 hp (108.126 kW) and 190 ft·lbf (258 N·m).
Applications:
- 1988-1992 Mazda 626
- 1988-1992 Mazda MX-6
- 1988-1992 Ford Probe
[edit] FS
The 2.0 L (1991 cm³) FS was one of the last F-family engines. With an 83 mm bore and 92 mm stroke, it produced 130 hp (97 kW) and 135 ft·lbf (183 N·m). In 1998 the engine underwent several changes, most notably a distributorless ignition and was called the FSDE.
Applications:
- 1993-2002 Mazda 626
- 1993-1997 Mazda MX-6
- 1999-2001 Mazda MPV (Japan)
- 1999-2003 Mazda Capella
- 2001-2003 Mazda Protegé
- 1993-1997 Ford Probe
A special turbocharged version of the FS was produced for the 2003 Mazdaspeed Protegé. It produced 170 hp (127 kW) and 160 ft·lbf (217 N·m).
In Japan a higher-performance version of the 1993-1997 FS engine was offered with a distributorless ignition and higher compression ratio, known as the FSZE.
[edit] FP
The 1.8 L (1839 cm³) FP used an 83 mm bore and 85 mm stroke. This engine is also sometimes incorrectly called the F8, referring to an earlier engine of the same capacity from the F engine family. It produced 122 hp (91 kW) and 120 ft·lbf (163 N·m). Comprehensively the same engine as the FS, the only glaring difference between two is displacement size and output. As with the previous 1.8l F engine, its lower displacement is achieved by destroking the existing FS.
Applications:
- 1992-1993 Eunos 500
- 1997-2001 Mazda Capella
- 1999-2000 Mazda Protegé (ES models only)
[edit] RF/R2
2.0 L RF and 2.2 L R2 - Diesel variants used in Mazda Cars that use the same engine blocks as the FE and F2, respectively.
