The HSC ("High Swirl Combustion") was an automobile engine from Ford Motor Company sold from 1984 until 1994. It was produced in Lima, Ohio, largely using tooling and designs adapted from the predecessor 200 in³ straight 6.
2.3
The 2.3 L (2311 cc, 141 in³) version was introduced in 1984 for the Ford Tempo/Mercury Topaz. Bore is 3.7 in (93.5 mm) and stroke is 3.3 in (83.8 mm). This engine produced 96 hp and 125 ft.lbf of torque. In 1985 a High Specific Output "HSO" model was introduced for the high-performance variants of the Tempo (GLS) and Topaz (LTS/XR-5). Output was 100 hp and 135 ft.lbf. This engine is denoted by an "S" in the VIN.
The early HSC engines were carbureted, with a 1-barrel Holley 6149 carburetor. Two-barrel Central Fuel Injection (CFI) was added in 1985. It was switched over to multi-port fuel injection in 1988. Sequential fuel injection was added for 1992 increasing horsepower to 98, but the HSO variant was dropped.
Applications:
- 1984-1994 Ford Tempo
- 1984-1994 Mercury Topaz
2.5
A 2.5 L (152 in³) version appeared in 1986 with longer 3.58 in (90.9 mm) stroke and electronic fuel injection. The extra displacement was needed to provide a four cylinder engine option for fleet customers of the new Ford Taurus. This engine used the head and cam from the HSO engine and produced 100 hp and 130 ft-lbs of torque. It sold in low volume (less than 15% of the HSC engines built) and was costly due to the tooling changeover required for the taller engine block deck height. It received sequential fuel injection in 1991, raising output to 105 hp and 140 ft-lbs of torque.
Applications:
- 1986-1991 Ford Taurus
- 1986 Mercury Sable
