The 2JZ engine is built on a cast-iron cylinder block, but with aluminium cylinder heads. It was originally equipped with four valves per cylinder until 1997, when Toyota introduced the variable valve timing (VVT-i), which improves the engine's efficiency. A 2JZ-GE engine is able to produce horsepower output between 215 PS to 230 PS.
The 2JZ-GTE, on the other hand, is based on the 2JZ-GE and shares the same mechanical basis, such as crankshaft and connecting rods. However, it utilizes the use of sequential twin turbochargers with an air-to-air side-mounted intercooler. New forged pistons with 8:5:1 compression is integrated into the power unit as well. Toyota has mounted oil spray bars to provide more cooling power to both the pistons and turbochargers. As for the markets outside of Japan, the engine is equipped with larger injectors and CT20A turbo with stainless steel blades, as opposed to the CT12B turbo with ceramic blades used in the Japanese market. As such, a 2JZ-GTE engine can delivers 325 PS, rather than contemporary industry maximum of 280 PS in Japan.Learn more about Engine
