Toyota Car Parts - 3S-GTE Engines

Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and various other components 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. Its cylinders are numbered 1-2-3-4, cylinder number 1 is beside the timing belt The cam journals are lubricated by oiler port located in the middle of the camshaft To adjust the valve clearance, adjust the shims above the valve lifters (shim over bucket system) The pent-roof combustion chambers are complemented by a cross flow intake and exhaust layout At the bottom of the cylinder block is an oil pan which stores the oil The first and second generations used the Toyota CT26, although the second-generation turbo was modified for increased reliability. The cam journal is supported on 5 points between the valve lifters of each cylinder and on the front of the cylinder head Depending on where the engine was intended to be sold the exhaust turbine is either ceramic (JDM) or steel (USDM). 5:1 or 8 The pistons are made from an aluminum alloy, design to withstand high temperatures The first two generations of 3S-GTE engines are equipped with TVIS It was fitted to the MR2 , Toyota Celica GT-Four, and the Caldina. The crankshaft, located within the crankcase, rotates on 5 aluminum alloy bearings and is balanced by 8 weights. 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. An indentation is incorporated into the pistons to prevent the pistons from 'knocking' into the valves. There are four generations of this engine, which started manufacture in 1986, and continues to the current day. 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.
