Toyota 2JZ GE/GTE/FSE Engine Specs, Problems, Reliability. The 2JZ engine was produced from 1991 to 2007. It is a 3.0-liter inline six-cylinder, gasoline engine, among the most popular Toyota engines, especially by the 2JZ-GTE twin-turbo variation used in the renowned Toyota Supra. But a common variation is the 2GZ-GE engine – naturally aspirated power unit, widely used in Toyota’s and Lexus’s automobiles (such as Toyota Altezza, Aristo, Soarer, Lexus IS300, GS300, and SC300) and well known for the great reliability and performance.
The basic architecture of the 2JZ resembles the 1JZ, but it is not simply a simple stroked variation. The cylinder block is made from cast iron, durable and strong material. The 2JZ engine block is taller than 1JZ due to increased stroke by 14.5 mm (0.57 in). A new crankshaft with increased stroke also needed longer connecting rods (they are hot-forged). The first generation 2GZ-GE had an aluminum cylinder head with a direct style – four valves per cylinders, centrally located spark plugs, and belt driven double overhead camshafts.

Consumption valve size is 33.5 mm; exhaust valve size – 29.0 mm. Camshaft requirements: period – 233/236 deg (intake/exhaust), valve lift 8.26/ 8.41 mm (intake/exhaust). The engine was geared up with a standard ignition system with a supplier and one ignition coil. The intake includes an aluminum intake manifold and Toyota’s ACIS system (variable length consumption). The naturally aspirated 2JZ has 10.5:1 compression ratio.
In 1997, Toyota released the 2nd generation in which engineers carried out VVT-i for the intake valve timing and advanced ignition system DIS (not a real Coil-On-Plug still, but with 1 ignition coil for two cylinders). 2JZ-GE VVT-i engines got brand-new connecting rods made of high-strength vanadium steel. Camshaft requirements for the 2JZ VVT-i: period – 233/226 deg (intake/exhaust). VVT-i engines go with Toyota’s Electronic Throttle Control System – intelligent (ETCS-i). All 2JZ variations (non-VVT-i and VVT-i also) had shimless pails in the valvetrain. The valve modification is needed every 60k miles (100k km). The production of the 2GZ-GE VVT-i stopped in 2005.
The 2JZ-GTE Engine
The twin-turbocharged 2JZ version was produced from 1991 to 2004. It was first introduced in the Toyota Aristo V (Japan) and then in the Toyota Supra (JZA80). This engine uses a 2JZ-GE engine block, crankshaft, and linking rods. The bottom features new pistons with recessed piston tops lowering compression ratio down to 8.5:1. Engineers likewise added oil spray nozzles for extra cooling of the pistons. The 2JZ-GTE got a brand-new cylinder head with reshaped intake and exhaust ports, brand-new valves and camshafts. The 2JZ turbo engine has its own intake manifold however it kept Toyota’s ACIS system. Like the 2JZ-GE in 1997, the twin-turbo 2JZ-GTE engine received Toyota’s VVT-i variable valve timing innovation for the consumption just. Late VVT-i 2JZ-GTE engines feature weaker connecting rods than non-VVT-i engines.
Engines for Japan domestic market (JDM) and for the North American/European markets have some distinctions in elements and, as a result, in performance. Japan designs are equipped with ceramic turbochargers CT20 (with the B, R, and A part number suffixes), 440 cc injectors, and camshafts with following specs: duration – 224/233 deg (intake/exhaust), valve lift 7.8/ 8.25 mm (intake/exhaust). These engines produced 280 hp at 5,600 rpm and 320 lb-ft (434 Nm) of torque at 4,000 rpm in non-VVT-i version. With the intro of VVT-i, the torque increased to 333 lb-ft (451 Nm).
Export designs were geared up with stainless-steel turbochargers CT12B, more productive injectors (550 cc/min), and other camshafts. USDM/EURO camshafts specifications: duration – 233/233 deg (intake/exhaust), valve lift 8.25/ 8.25 mm (intake/exhaust). 2JZ-GTE engines for export models are more effective: 320 hp at 5,600 rpm and 315 lb-ft (427 Nm) at 4,000 rpm for the United States, and 325 hp/325 lb-ft (440 Nm) for Europe.
The 2JZ-FSE Engine
The 3.0-liter Toyota 2JZ-FSE engine was produced from 1999 to 2007. The engine features in the first place a direct injection system D4, high compression ratio 11.3:1, and it features VVT-i only. The engine output resembles NA 2JZ-GE – 217 hp of power at 5,600 and 217 lb-ft (294 Nm) of torque at 3,600. The 2JZ-FSE is always used with an automatic gearbox.
2JZ GE/GTE/FSE Engine Problems and Reliability
2JZs are popular for incredible toughness. However they also have some common problems found after thousands of miles. Non-VVT-i engines are easier and trusted than with VVT-i. But they both perform not well in a cold weather condition and sensitive to moisture. The weak point is a water pump in addition to the actuator of the VVT-i system. Another common problem is the failure of among the ignition coils which leads to misfiring in 2 cylinders. Turbocharged engines for Japan market have turbochargers with ceramic wheel, which prone to break down under high loads prematurely.
The 2JZ engine can reach a 300k mileage mark easily with proper maintenance and quality engine oil, filters. It also uses an excellent opportunity for tuning, revealing impressive power outputs for a small number of upgrades and modifications.
