Toyota 3.0L 2JZ-GTE Twin Turbo Non-VVTi Engine

Description

The Toyota 3.0L 2JZ Twin Turbo Non-VVTi Engine was produced from 1991 to 2007. It is a 3.0-liter inline six-cylinder, petrol engine, one of the most famous Toyota engines, especially by the 2JZ-GTE twin-turbo version used in the iconic Toyota Supra.

But a common version is the 2GZ-GE engine – naturally aspirated power unit, widely used in Toyota’s and Lexus’s cars (such as Toyota Altezza, Aristo, Soarer, Lexus IS300, GS300, and SC300) and well known for the great reliability and performance. The general architecture of the 2JZ is similar to the 1JZ, but it is not just a simple stroked version. The cylinder block is made of cast iron, strong and durable material.

The 2JZ engine block is taller than 1JZ due to increased stroke by 14.5mm (0.57 in). A new crankshaft with increased stroke also required longer connecting rods (they are hot-forged).

The first generation 2GZ-GE had an aluminum cylinder head with a straight forward design – four valves per cylinders, centrally located spark plugs, and belt driven double overhead camshafts. Intake valve diameter is 33.5 mm; exhaust valve diameter – 29.0 mm. Camshaft specifications: duration – 233/236 deg (intake/exhaust), valve lift 8.26/8.41 mm (intake/exhaust). The engine was equipped with a traditional ignition system with a distributor and one ignition coil. The intake includes an aluminum intake manifold and Toyota’s ACIS system (variable length intake). The naturally aspirated 2JZ has 10.5:1 compression ratio.
