3S-GTE was Toyota’s 2 litre inline 4 turbocharged performance engine mainly used to power most powerfull version of Toyota Celica and MR2 models between 1986 to 1999. 3S-GTE was also used on Toyota Caldina GT-4 and GT-T models between 1997 to 2002. 3S-GTE shared the same block cast iron block with its non-turbo sister 3S-GE. The only exceptions were turbocharger oil passages and piston oil coolers present on 3S-GTE. 86mm bore and 86 mm stroke swept a total displacement of 1998cc. The aluminum alloy head featured dual over head cams and 4 valves per cylinder that measured 33.5mm for intake and 29.0mm for exhaust. To increase combustion efficiency, cross flow intake and exhaust layout was coupled with pent-roof combustion chambers. Fuel injectors were placed on the side of the head as opposed to 3S-GE which had the injectors on its top. Toyota continued developing 3S-GTE through out its life span. Although there is no such official classification from Toyota, 3S-GTE engines are generally collected under four generations.
