Roizska: 2JZ

2JZ

The 2,997 cc (3.0 L; 182.9 cu in) 2JZ has been produced since 1991 (first released in the 1991 Toyota Aristo). Cylinder bore and stroke is 86 mm × 86 mm (3.39 in × 3.39 in). VVT-i variable valve timing was added later in 1997 for the 1998 model year. This engine is not merely a stroked version of the 1JZ (although they share a common bore size, bore pitch, and general architecture), but has a taller block deck and longer connecting rods to accommodate the 14.5 mm (0.57 in) stroke increase.

2JZ-GE

The 2JZ-GE is a common version. Output is 215–230 PS (158–169 kW; 212–227 bhp) at 5800 to 6000 rpm and 209–220 lb⋅ft (283–298 N⋅m) of torque at 4800 to 5800 rpm.

It uses Sequential Electronic Fuel Injection, has an aluminum head and 4 valves per cylinder, along with a cast-iron cylinder block, with some versions using VVT-i. The VVT-i version also featured DIS in favor of the traditional distributor set-up previously seen on the 2JZ-GE. Despite common misconception it was not a true COP (Coil-On-Plug, also known as Plug-top coil) ignition system instead relying on one coil to fire two cylinders, one of which was by spark plug wire.

2JZ-GTE

The 2JZ-GTE is an inline-layout, six-cylinder, belt-driven dual overhead camshaft, air-intercooled, twin-turbocharged, cast-iron block, aluminium cylinder headed engine designed and manufactured by Toyota Motor Corporation that was produced from 1991 until 2002 in Japan. Development and evolution of the engine was, principally, a response to Nissan's relatively new and then-successful RB26DETT engine^{[citation needed]} which had achieved palpable success in FIA Group A and Group N touring car championships.

For all road car applications, two gearboxes were available for the engine:

Toyota A340E 4-speed automatic
Toyota V160 and V161 6-speed manual (jointly developed with Getrag as the Type 233)

The 2JZ-GTE originally powered the Toyota Aristo V (JZS147) in 1991 before becoming Toyota's flagship performance engine in the Toyota Supra RZ (JZA80). Its mechanical basis was the existing 2JZ-GE, but differed in its use of sequential twin turbochargers and an air-to-air side-mounted intercooler. The engine block, crankshaft, and connecting rods of the Supra's 2JZ-GE and 2JZ-GTE are the same, with notable differences being that the 2JZ-GTE has recessed piston tops (giving a lower compression ratio), oil spray nozzles to aid in cooling the pistons and a different head (redesigned inlet/exhaust ports, cams and valves). Toyota's VVT-i variable valve timing technology was added to the engine beginning in September 1997, hence it phased out the original engine. Consequently, maximum torque and horsepower was raised for engines selling in all markets. These later 2JZ-GE VVT-i equipped models (Aristo, Altezza, Mark II) share a different part number for weaker connecting rods.

The addition of twin turbochargers, jointly developed by Toyota with Hitachi, in sequential configuration had raised its commercially cited output from 230 PS (169 kW; 227 hp) to the contemporary industry maximum of 280 PS (206 kW; 276 hp) at 5600 rpm. In its first appearance, torque was advertised as 44.3 kg⋅m (320 lb⋅ft; 434 N⋅m) at 4000 rpm to be later recited as 46 kg⋅m (333 lb⋅ft; 451 N⋅m) with the introduction VVT-i in production year 1997. The mutually agreed, industry-wide output ceiling was enforced by Japan's now-defunct Gentlemen's Agreement exclusively between Japanese automakers selling to the Japanese domestic market. Engine power in the North American and European markets, as documented by Toyota, was increased to 325 PS (239 kW; 321 hp) at 5600 rpm.^[4]

The export version of the 2JZ-GTE achieved its higher power output with the use of newer stainless steel turbochargers (ceramic for Japanese models), revised camshafts, and larger injectors (550 cc/min for export, 440 cc/min for Japanese). The mechanical similarities between the Japanese-specification CT20 turbine and export-specification CT12B turbine allow interchangeability of the exhaust-side propeller shaft. Additionally, the export-exclusive CT12B turbine received more durable turbine housings and stainless steel turbine and impeller fins. Multiple variants of the Japanese CT20 turbine exist discretely, which are identified with the B, R, and A part number suffixes (e.g.: CT20A).

2JZ-FSE[edit]

The 3-litre 2JZ-FSE uses the same direct injection principle as the smaller 1JZ-FSE but runs an even higher 11.3:1 compression ratio. This engine matches the conventional VVT-i 2JZ-GE with 162 kW (217 hp; 220 PS) and 294 N⋅m (217 lb⋅ft) of torque. The 2JZ-FSE is always used with an automatic transmission. Weight: 200 kg (440 lb)
