The Toyota JZ engine family is a series of inline-6 automobile engines.
1JZ
The 2.5 L (2491 cc) 1JZ version was produced from 1990 through 2005 (still in production with the Mark II BLIT Wagon). Cylinder bore was 86 mm (3.39 in) and stroke was 71.5 mm (2.81 in). It was a 4-valve DOHC engine with two belt-driven camshafts.
Output for the non-turbo 1JZ-GE was 200 hp JIS (147 kW) at 6000 rpm and 185 ft.lbf (250 Nm) at 4000 rpm.
1JZ-GTE
The twin-turbo 1JZ-GTE. Although rated at Japan's self-imposed maximum rating of 280 hp (206 kW), this was probably quite conservative. A later unit (with VVT-i and a single turbo) probably produced well more than 300 hp (221 kW). Torque was rated at 278 ft·lbf (376 N·m) at 2400 rpm.
Applications:
- 1989–1992 Toyota Supra MK3 (chassis code JZA70, non-US only)
- Toyota Soarer
- Toyota Chaser/Cresta/Mark II Tourer V
2JZ
The 3.0 L (2997 cc) 2JZ has been produced since 1992 (first released in the 1992 Lexus SC300). Cylinder bore was 86 mm (3.39 in) and stroke was 86 mm (3.39 in). VVT-i variable valve timing was added later in 1997.
2JZ-GE
The 2JZ-GE is a common version. Output is 215 to 230 hp JIS (158 to 169 kW) at 5800 to 6000 rpm and 209 to 220 ft.lbf (283 to 298 Nm) of torque at 3800 to 4800 rpm.
It uses SEFI fuel injection, has an aluminum head and 4 valves per cylinder with some versions using VVT-i, along with a cast iron cylinder block.
Applications:
- 1993-2002 Toyota Supra MK4
- Toyota Aristo
- Toyota Progres
- Toyota Crown
- Toyota Mark II
- Lexus IS 300
- Lexus GS 300
- Toyota Soarer
- Lexus SC 300
2JZ-GTE
The 2JZ-GTE was developed to power the fourth generation of the Supra sports car. It was based on the 2JZ-GE, but differed in its use of sequential twin turbochargers.
The use of sequential twin CT12B turbochargers raised its power output from a mere 166 kW (225 hp DIN) to 206 kW (280 hp DIN) at 5600 rpm, officially limited in the Japanese and European markets, although the real undisclosed figure was well in excess of 300 hp (over 220 kW). In the American market, power was raised to 239 kW (320 hp SAE) at the same 5600 rpm. This engine is very popular with tuners for its high horsepower potential and reliability. Modified versions of the 2JZ-GTE have been seen with over 1500hp. Notable is Marko Djuric's '93 Toyota Supra, a street driven vehicle with a stock displacement 2JZ-GTE that dynoed 1520 horsepower at the rear wheels in 2004, still running on gasoline.
Applications:
- 1993-2002 (In the US from '93-'98) Toyota Supra MK4
- Toyota Aristo
