Ford HSC engine


The HSC is 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 200 CID straight-6. The engine was introduced as an alternative to the 2.3 L overhead-cam Lima engine, for which demand had been higher than the installed capacity for its production at that time.

The version was introduced in 1984 for the Ford Tempo/Mercury Topaz. Bore and stroke is. This engine produced and of torque. The HSC was Ford's first production "fast burn" engine.
1985 brought two significant changes. American-market engines received Central Fuel Injection, which reduced power to. Ford remedied the power decrease with a High Specific Output "HSO" model, introduced for the high-performance variants of the Tempo and Topaz. Output was and of torque. This engine is denoted by an "S" in the VIN.
The early HSC engines were carbureted, with a 1-barrel Holley 6149 carburetor. Single point Central Fuel Injection was added in 1985. It was switched over to multi-port fuel injection in 1988 which raised horsepower to. Sequential fuel injection was added for 1992 increasing horsepower to, but the HSO variant was dropped.
Applications:
A version appeared in 1986 with longer stroke and electronic multi-port 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 and of torque. It sold in low volume 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 and of torque.
