The JZ family of Toyota Engines is a Noble One
The JZ engine series is a group of inline-6 engines. The JZ group replaced Toyota’s M series. JZ engines were offered in 2.5 and 3.0 liter versions. The 1JZ 2.5 liter engine was produced from 1990 to 2007 with two belt-driven camshafts. Two more generations followed the 1JZ: the 1JZ-GE and the 1JZ-GTE. Both of those engines produced more horsepower and more torque that the first 1JZ. Searching for Toyota Engines for Sale, 2JZ, very affordable and ready to ship for your convenience.
The 2JZ engine made its debut in 1991 in Toyota’s Aristo model. It had a bore size of 3.39 inches and a stroke size of 3.39 inches. The VVT-i (variable valve timing) version didn’t come on the engine scene until 1997 and that was for the 1998 model year. The most common version of the 2JZ is the 2JZ-GE, which has 220 horsepower at 5800 rpms and 220 ft-lbs of torque at 3800 rpms. The 2JZ-GE uses a Sequential Electronic Fuel Injection System. It has 4 valves per cylinder and some versions use VVT-i with a cast iron cylinder block instead of aluminum.
The 2JZ-GTE engine was produced in Japan. It was a response to Nissan’s very successful RB26DETT engine, which achieved success in the FIA Group A and Group N car championships. The final development of the 2JZ-GTE was outsource to a German engineering firm so it could be refined to meet the production requirements established by the All-Japan Touring Car Championships.
The 2JZ-GTE became Toyota’s flagship performance engine. It was a big hit in the Toyota Supra. The mechanical base for the engine was the 2JZ-GE, but the air-to-air side mounted intercooler, and the twin turbochargers put it in a class of its own even though the block, connecting rods, and the crank were the same as the 2JZ-GE.
Hitachi Helped Toyota Develop Twin Turbochargers
There was a gentlemen’s agreement in Japan that controlled engine output in Japan’s domestic car market, but that agreement is no longer in place. Once the agreement was dissolved, engine horsepower went from 276 to 325 horsepower at 5600 rpms almost overnight. Toyota needed help from Hitachi in order to develop the sequential configuration that could raise the engine’s output. The export version of the 2JX-GTE reached that output using new stainless steel twin turbochargers, which were developed from that union.
