Toyota Car Parts - 3S-GTE Engines

The cast iron cylinder block holds 4 86mm pistons and has a stroke of 86mm The 1st compression ring and the oil ring is made of steel, the 2nd compression ring is made of cast iron Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and various other components 8:1 depending on generation Depending on where the engine was intended to be sold the exhaust turbine is either ceramic (JDM) or steel (USDM) Due to the design of the intake manifold, cylinder number 3 runs lean under normal operation The compression ration is 8 A single timing belt drives the intake and exhaust camshaft along with the oil and water pumps It was fitted to the MR2 , Toyota Celica GT-Four, and the Caldina. At the bottom of the cylinder block is an oil pan which stores the oil There are four generations of this engine, which started manufacture in 1986, and continues to the current day. 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 turbochargers used in the 3S-GTE engines are Toyota designs. 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 third generation uses a normal 4-runner intake manifold. An indentation is incorporated into the pistons to prevent the pistons from 'knocking' into the valves 5:1 or 8. Its cylinders are numbered 1-2-3-4, cylinder number 1 is beside the timing belt. This prevents oil from being shifted away from the oil pump suction pipe 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 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. This allows for the replacement of the shims without the need to remove the camshaft. The first two generations of 3S-GTE engines are equipped with TVIS. 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. Built into the cylinder block are coolant channels, which cools the block which houses the crankshaft.
