The Toyota S Series Engine

Introduction of the S Series Engine

The Toyota S Series of engines are four-cylinder (straight-4) models that were introduced in 1982 and discontinued in 2007. These engines were replaced by the AZ and AR engine series. The S Series is noted for his robust cast iron block and alloy heads configured for efficient operation in the 2-liter range. It was a staple of Toyota performance engines until its replacement.

3S-GE

first-generation 1S appeared in the Camry and Celica as part of their LASRE family (lightweight advanced super response engine). The second-generation appeared briefly, but was replaced before 1988 by the third-generation.

The 3S-FC appears in the 1987-1991 Camry while the 3S-FE appears in the Celica SSI from 1987-1994. The 3S-GE appears in the Celica 2.0 GT-i 16, the 1985-1989 GT-R and MR2, and the 1994-1998 Celica GT and MR2. The 3S-GT appears in several GT models and race-ready platforms, including the 1995-1996 Supra GT. The 3S-GTE appears in the 1986-2007 Celica GT-Four.

The fourth-generation (4S) came along for less sporty applications. The 4S-FE entered the Corona in 1989 through 1998. The fifth-generation 5S-FE entered the MR2 and Camry in 1990 and stayed through 2001 and was featured in special editions of that car as well.
