The major difference between the 3SGE and 3SFE is the usage of a modified cylinder head developed by the Yamaha specialists. 3S-GE (1985 – 2005) is a sporting type of the 3S-FE engine.
Besides, there can be some problems connected with the catalytic converter, fuel injectors demanding a constant care and scour, and spark plugs condition demanding a constant control, etc.Ĥ. The main problems are connected with the high pressure fuel pump (HPFP) failures, EGR failures, inlet manifold demanding a regular scour. In spite of its workability, the 3S-FSE engine is not as reliable, as 3S-FE. The 3S-FE compression ratio was 9.8, its power was 150 HP at 6,000 rpm, and torque was 192 Nm (142 lb Variable valve timing technology VVTi with an inlet valve, variable intake system, modified pistons, altered injectors and spark plugs, electronic throttle body, valve EGR were installed on that engine. 3S-FSE D4 (1997 – 2003) is the first Toyota engine with direct fuel injection. The motor was installed in Avensis, Caldina, Carina, Camry, Celica, Corona, Ipsum, MR2, RAV4.ģ. The compression ratio of 3S-FE is 9.8 and its power is from 115 HP to 130 HP, depending on a type and broach. 3S-FE (1986 – 2000) is a type of engine with an injector fuel feed system. The compression ratio is 9.8, power is 111 horsepower at 5,600 rpm, torque is 166 Nm (122 lb 3S-FC (1986 – 1991) is a type of engine with a carburetor fuel feed system designed especially for such cheap modifications as Camry V20 and Holden Apollo. Toyota 3S engine modifications and differencesġ. Below you will find a detailed overview of each version. Over the long period of production, Toyota 3S has been corrected, modified and improved. Toyota 3S, however, has not been completely superseded until 2007. There were also some other S engine versions produced on the basis of Toyota 3S: 1.8-liter 4S and 2.2-liter 5S.ġAZ-FE replaced 3S in 2000. The timing gear uses a belt requiring replacement every 60,000 miles (100,000 km) of mileage. Valve clearances for a cold engine are as follows: inlet 0.19 – 0.29 mm, exhaust 0.28 – 0.38 mm. As there are no hydraulic lifters on the 3S engine, you need to adjust the valves every 20,000 miles (30,000 km) of mileage. The replace of cylinder head by a 16 valve twincam has greatly improved the engine performance. Toyota 3S also has a new crankshaft with a piston stroke of 86 mm. The diameter of 3S cylinders is up to 86 mm.
The production of 3S started in 1984 on the basis of 2S cylinder block. Toyota 3S is one of the most mass produced motors of Toyota S-series. Toyota 3S-GE engine ( 3SGTE, 3SFE) reliability, problems and repair Normal engine operating temperature, ☌ (F)
