Toyota Car Parts - 3S-GTE Engines

The first two generations of 3S-GTE engines are equipped with TVIS This allows for the replacement of the shims without the need to remove the camshaft The first and second generations used the Toyota CT26, although the second-generation turbo was modified for increased reliability At the bottom of the cylinder block is an oil pan which stores the oil The cam journal is supported on 5 points between the valve lifters of each cylinder and on the front of the cylinder head Piston pins holding the pistons in place are locked by snap rings 5:1 or 8 The compression ration is 8 Compression ring 1 and 2, prevents gas leakages from the combustion chamber while the oil ring works to clear oil off the cylinder walls, preventing any excessive oil from entering the combustion chamber Spark plugs are located in the middle of the combustion chambers. The crankshaft, located within the crankcase, rotates on 5 aluminum alloy bearings and is balanced by 8 weights Due to the design of the intake manifold, cylinder number 3 runs lean under normal operation The 3S-GTE is an in-line 4-cylinder 1998cc engine from Toyota, based on the 3S-GE with reduced compression ratio and addition of a turbocharger. 8:1 depending on generation There are four generations of this engine, which started manufacture in 1986, and continues to the current day. The cam journals are lubricated by oiler port located in the middle of the camshaft. On the first two generations the intake manifold has 8 independent ports and benefits from the inertia build up to improve engine torque at low and medium speeds. The cast iron cylinder block holds 4 86mm pistons and has a stroke of 86mm An indentation is incorporated into the pistons to prevent the pistons from 'knocking' into the valves. The 1st and 3rd Celica generation intake charge was cooled by a Water to Air intercooler while the 2nd, 3rd MR2, and 4th generation relied on an Air to Air system. The 1st compression ring and the oil ring is made of steel, the 2nd compression ring is made of cast iron. A single timing belt drives the intake and exhaust camshaft along with the oil and water pumps.
