Based on this 1SZ-FE, two 1.3L versions were developed, 2SZ-FE and K3-VE, using the same crankshaft but different cylinder block and vastly different cylinderhead. By this time, the VVT-i was slightly modified by Daihatsu to be called the DVVT and was used on the K3 engines (except K3-DE).
The 1.3-liter Toyota 2SZ-FE engine was produced from 1999 to 2016 in China and Indonesia for the concern’s compact models. The motor was equipped with a VVT-i phase regulator only at the inlet, and the gas distribution mechanism of the unit was driven using a Morse chain.
Learn about frequent 2SZ engine problems, symptoms, causes, and practical solutions for Toyota and Daihatsu models using the 2SZ-FE engine.
The Toyota 2SZ-FE is a compact 1.3-liter gasoline engine from the SZ series, designed for city cars: Toyota Yaris, Vitz, Belta, Porte, Raum, and some Daihatsu models.
In 2002, on the basis of the K3-VE, two completely dissimilar versions were created, which received the same Toyota designation 2SZ-FE: one for European (Yaris 10..90), the second for Japanese market (Vitz 10..90, Belta, Ractis).
The 2SZ-FE engine represents Toyota’s approach to small-displacement powertrains during the early 2000s, emphasizing fuel efficiency, compact packaging, and reliability within the constraints of the subcompact vehicle segment.
Since 2006, the 2SZ-FE engine has largely been installed in Compact car models. It is a 1,3-liters-in-line engine with 4 cylinders that is used in various models of Toyota.
The Toyota SZ engine family is a straight-4 piston engine series with its exhaust facing forward.This engine was jointly developed by Daihatsu. codes are 1SZ-FE (1.0L), 2SZ-FE (1.3L) 3SZ-VE (1.5L)
