P

The 1.0 L (997 cc) P was produced from 1959 through 1961. Bore and stroke are 69.9 mm × 65 mm (2.75 in × 2.56 in).

2P

The 1.2 L (1,198 cc) 2P was produced from 1961 through 1972. This was bored out to 76.6 mm (3.02 in), while retaining the short 65 mm (2.56 in) stroke. Power is 55 PS (40 kW; 54 hp) at 5,000 rpm, while torque is 8.8 kg⋅m (86 N⋅m; 64 lb⋅ft) at 2,800 rpm.[2]

3P

The 1.3 L (1,345 cc) 3P was produced from 1967 through 1979. Bore and stroke is 76.6 mm × 73 mm (3.02 in × 2.87 in). Power is usually 65 PS (48 kW; 64 hp) at 5,000 rpm, with torque of 10.3 kg⋅m (101 N⋅m; 75 lb⋅ft) at 3,000 rpm.[5][6]

4P

The 1.5 L (1,493 cc) 4P (retaining the 76.6 mm (3.02 in) bore but with a longer 81 mm (3.19 in) stroke) mostly saw use in off-road equipment such as forklifts and loaders, where it was used until at least 1994 for the Toyota 5FGL. It produces 30 PS (22 kW; 30 hp) at 2400 rpm as fitted to the Toyota 2SGK6 loader (1993).[10] In the 1972 2FG20 2-ton forklift it has 35 PS (26 kW; 35 hp) at 2800 rpm.[11]
