The Toyota SZ engine family is a series of straight-4 piston engines with a forward-facing exhaust. Toyota Motor Manufacturing (UK) in Deeside produces SZ engines for the Yaris. All three types of the SZ engine are built in Tianjin FAW Toyota Engine Co., Ltd. (TFTE) Plant No. 1 in Xiqing District, Tianjin, China. The 2SZ-FE and 3SZ-FE variations are also manufactured by PT Astra Daihatsu Motor's Karawang Engine Plant in Indonesia.
The 1SZ-FE was jointly developed by Toyota and Daihatsu. It is 1.0 L (997 cc). 4 valve per cylinder. Bore and stroke is 69 mm × 66.7 mm (2.72 in × 2.63 in), with a compression ratio of 10.0:1. Output is 51.5 kW (69.1 hp; 70.0 PS) at 6000 rpm with 95 N⋅m (70 lbf⋅ft) of torque at 4000 rpm. It features VVT-i, off-set type crankshaft which reduces friction losses and narrow-angle valves. Engine weight of 68 kg (150 lb); was achieved by using cast-iron cylinder block produced by cold-box method.
The 2SZ-FE is 1.3 L (1,298 cc). Bore and stroke is 72 mm × 79.6 mm (2.83 in × 3.13 in), with a compression ratio of 11.0:1. Output is 64 kW (86 hp; 87 PS) at 6000 rpm with 122 N⋅m (90 lbf⋅ft) of torque at 4200 rpm. Daihatsu's internal code for this engine is labeled as K3-DE/VE and the turbocharged version as K3-VET. The engine features VVT-i (except for K3-DE model).
