Toyota Car Parts - 3S-GTE Engines

Piston pins holding the pistons in place are locked by snap rings The third generation uses a normal 4-runner intake manifold 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 There are four generations of this engine, which started manufacture in 1986, and continues to the current day. Spark plugs are located in the middle of the combustion chambers Due to the design of the intake manifold, cylinder number 3 runs lean under normal operation The compression ration is 8 The Dual Over Head Cam (DOHC) 16 valve cylinder head designed by Yamaha is made of aluminum alloy. Depending on where the engine was intended to be sold the exhaust turbine is either ceramic (JDM) or steel (USDM). Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and various other components This allows for the replacement of the shims without the need to remove the camshaft Up to 260 hp in stock engine. The cam journal is supported on 5 points between the valve lifters of each cylinder and on the front of the cylinder head Various aftermarket solutions exist all of which require replacing the intake headers or manifold. Built into the cylinder block are coolant channels, which cools the block which houses the crankshaft 8:1 depending on generation It was fitted to the MR2 , Toyota Celica GT-Four, and the Caldina. The first and second generations used the Toyota CT26, although the second-generation turbo was modified for increased reliability. The pent-roof combustion chambers are complemented by a cross flow intake and exhaust layout. A single timing belt drives the intake and exhaust camshaft along with the oil and water pumps.
