Toyota Car Parts - 3S-GTE Engines

The compression ration is 8 An indentation is incorporated into the pistons to prevent the pistons from 'knocking' into the valves The pent-roof combustion chambers are complemented by a cross flow intake and exhaust layout The pistons are made from an aluminum alloy, design to withstand high temperatures 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 Depending on where the engine was intended to be sold the exhaust turbine is either ceramic (JDM) or steel (USDM). The 1st compression ring and the oil ring is made of steel, the 2nd compression ring is made of cast iron It was fitted to the MR2 , Toyota Celica GT-Four, and the Caldina. There are four generations of this engine, which started manufacture in 1986, and continues to the current day. Built into the cylinder block are coolant channels, which cools the block which houses the crankshaft 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 5:1 or 8 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. Various aftermarket solutions exist all of which require replacing the intake headers or manifold. This prevents oil from being shifted away from the oil pump suction pipe The third generation uses a normal 4-runner intake manifold. Up to 260 hp in stock engine. The first and second generations used the Toyota CT26, although the second-generation turbo was modified for increased reliability. A single timing belt drives the intake and exhaust camshaft along with the oil and water pumps. Due to the design of the intake manifold, cylinder number 3 runs lean under normal operation. The crankshaft, located within the crankcase, rotates on 5 aluminum alloy bearings and is balanced by 8 weights. 8:1 depending on generation. The Dual Over Head Cam (DOHC) 16 valve cylinder head designed by Yamaha is made of aluminum alloy. The cast iron cylinder block holds 4 86mm pistons and has a stroke of 86mm.
