Toyota Car Parts - 3S-GTE Engines

Up to 260 hp in stock engine 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 An indentation is incorporated into the pistons to prevent the pistons from 'knocking' into the valves The first and second generations used the Toyota CT26, although the second-generation turbo was modified for increased reliability. 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. 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 At the bottom of the cylinder block is an oil pan which stores the oil The crankshaft, located within the crankcase, rotates on 5 aluminum alloy bearings and is balanced by 8 weights The pistons are made from an aluminum alloy, design to withstand high temperatures 5:1 or 8 The third generation uses a normal 4-runner intake manifold The compression ration is 8 Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and various other components Various aftermarket solutions exist all of which require replacing the intake headers or manifold A panel is used to ensure that there are sufficient oil available in the oil pan, as the oil moves around the reservoir during movement of the vehicle Due to the design of the intake manifold, cylinder number 3 runs lean under normal operation. The third-generation engine uses the Toyota CT20b dual-entry turbo, and the fourth uses a proprietary CT20b turbocharger whose exhaust housing is actually cast into the cylinder exhaust manifold, rather than the normal practice of a separate exhaust housing after the cylinder exhaust manifold and it can only be used on the 4th Gen 3sgte head and not backwards compatible like the CT20b of the 3rd Gen 3sgte. The turbochargers used in the 3S-GTE engines are Toyota designs. The Dual Over Head Cam (DOHC) 16 valve cylinder head designed by Yamaha is made of aluminum alloy. Piston pins holding the pistons in place are locked by snap rings There are four generations of this engine, which started manufacture in 1986, and continues to the current day. 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. It was fitted to the MR2 , Toyota Celica GT-Four, and the Caldina. 8:1 depending on generation. The first two generations of 3S-GTE engines are equipped with TVIS.
