Mazda C engine

The C family was Mazda's first large piston engine design. It is not certain whether Mazda has a name for this collection of engines, and it is uncertain precisely which ones are related.

PC
The 985 cc PC engine featured a 70x64 mm bore and stroke. It was an eight-valve SOHC design and was designed for rear wheel drive longitudinal applications. The PC produced 45 PS and 7 kgm in the export market 323.

Applications:
 * 1965–1967 Mazda Familia 1000 Coupé
 * 1977–1983 Mazda Familia/323 (FA4P)

TC
The 1272 cc TC had a 73x76 mm bore and stroke; a bored and stroked version of the PC. Used in the 1970, 1973, and 1977 Mazda Familia, and the 1979 - 1984 Mazda Bongo / Ford Econovans as the smaller engine option, the larger being the 1.6 L Mazda NA engine. For 1977 a new, prize-winning lean burn version of the TC was developed for the new FA-series Familia, using a carburetor with an EGR valve. Thus equipped, the TC weighs 127 kg.

UC
1415 cc 77x76 mm - A larger-bored version of the TC, used in the 1978-1980 Mazda GLC. Produced 70 hp. This was also used in the 1979-1984 E1400/Econovan and for the new 1984 Ford Econovan as the base model engine. In continental Europe the Econovan/Mazda E-series continued to use the UC engine until at least 1990, in a version which produces 48 kW. In some parts documentations, it is referred to as the D4, however no UC engine block was ever stamped D4. in 1980, this engine (and the smaller TC) was modernized and turned into the new E-series engine, intended for front-wheel drive applications.

UB
The original 1966 Luce 1500 used a 1490 cc SOHC inline-four with square 78 mm bore and stroke. This engine, also used in the Capella and Grand Familia for a short while, was replaced by the stroked NA engine (below).

US-spec was 70 hp at 5000 rpm, with maximum torque of 11.3 kgm at 3500 rpm with a single Nikkei carburetor. The rest of the world received a 75 hp version.
