1A The 1.5 L (1452 cc) 1A was produced in 1978 and 1979. It was a 2-valve SOHC engine. 2A The 1.3 L (1295 cc) 2A was produced from 1979 through 1986. Cylinder bore was 76 mm (2.99 in) and stroke was 71.4 mm (2.81 in). It was a 2-valve SOHC design like its predecessor. Output ranged from 65-75 hp (48-56 kW) at 5400-6000 rpm and 72-79 ft·lbf (97-107 N·m) at 3600 rpm. 3A The 1.5 L (1452 cc) 3A was produced from 1979 through 1988. Cylinder bore was 77.5 mm (3.05 in) and stroke was 77 mm (3.3 in). It was a 2-valve SOHC like the 1A and 2A. There were California-spec (3A-C), Japan-spec (3A-U), transverse (3A-L), and swirl-intake (3A-S) versions of the same basic design. Power output ranged from just 62 hp (46 kW) at 4800 rpm all the way to 90 hp (67 kW) at 6000 rpm. Torque was less spread from 75 ft·lbf (101 N·m) at 2800 rpm to 89 ft·lbf (120 N·m) at 4000 rpm. 4A The 4A was produced from 1980 through 1998. All 4A engines have a displacement of 1.6 L (1587 cc). Cylinder bore was enlarged from the previous 3A engines at 81 mm (3.19 in), but stroke remained the same as the 3A at 77 mm (3.03 in). Numerous variations of the basic 4A design were produced, from SOHC 2-valve all the way to DOHC 5-valve versions. Power was also extremely varied, from 70 hp (52 kW) at 4800 rpm in the basic California-spec 4A-C to 170 hp (127 kW) at 6400 rpm in the supercharged 4A-GZE. 4A-C The basic 4A and Cal-spec 4A-C was an SOHC 8-valve carbureted engine, rated at 70-90 hp (52-67 kW) at 4800 rpm. Torque was good for a small engine, at 85 ft·lbf (115 N·m) at 2800 rpm in even the "strangled" early-1980s California-spec version. 4A-E fuel injection was added for the 1981 through 1988 4A-E. This pushed output to 78 hp (58 kW) at 5600 rpm and 87 ft·lbf (117 N·m) at 4000 rpm in export form. A special Japan-spec transverse 4A-ELU was also produced in 1986. Output for this engine was 100 hp (75 kW) at 5600 rpm and 101 ft·lbf (136 N·m) at 4000 rpm. 4A-F A narrow-valve (22.3°) DOHC 4-valve carb version, the 4A-F, was produced from 1987 through 1990. Output was 90 hp (67 kW) at 6000 rpm and 95 ft·lbf (128 N·m) at 3600 rpm. Toyota models that have had this engine: Corolla AE92 SR5 - FWD
