General information about the 4AGE 16v & 20v & 4AGZE.

The first-generation 4A-GE replaced the 2T-G in most applications. It was extremely light and strong for an all-iron engine block, and production lasted through 1990. The second-generation added piston-cooling oil sprays and higher compression ratios. The third-generation appeared in late 1991 with the 20 valve 4A-GE, which was itself updated in 1996 before being retired in 1998.


The next major modification was the high-performance 4A-G, with the fuel injected version, the 4A-GE, being the most powerful. Production of the various models of this version lasted for three generations, from 1983 through 1992 for most versions, though the 5-valve 4A-GE lasted through 1998. Most 4A-Gs were 4-valve DOHC engines with wide (50°) valve spacing for performance.

Power output for the 4-valve version varied widely, from 112 hp (84 kW) at 6600 rpm to 138 hp (103 kW) at 7200 rpm. Again, torque was closer, varying from 97 ft·lbf (131 N·m) at 4800 rpm to 110 ft·lbf (149 N·m) at 4800 rpm.

Special versions included the Japan-spec 4A-GEU, California-spec 4A-GEC, and even a Finnish-spec 4A-GE, as well as the transverse-mounted 4A-GEL. The engine was used in the company’s flagship car, the Toyota Corolla, in the 1980s.

The engine was first introduced in the 1983 Sprinter Trueno AE86 and the Corolla Levin AE86 sports version. The AE86 marked the end of the 4A-GE as a rear wheel drive (RWD or FR) mounted engine, alongside the RWD AE86/AE85 coupes a front wheel drive (FWD or FF) corolla (the AE82) was produced and future corolla/sprinter’s were all based around the FF layout. The engine was retired from North American Corollas in 1991, although it continued to be available in the Geo Prizm GSi (sold through Chevrolet dealerships) from 1990-1992.The 4A-GE was one of the earliest inline-4 engines to have both DOHC 16 valves and electronic fuel injection (EFI). Toyota designed this engine with performance in mind; its twin camshafts are 50 degrees apart to allow decent power, but this sacrifices torque. This engine is very popular with racers and tuners because of its ease of modification, simple design, and lightness.

Toyota models that have had this engine:

  • Toyota MR2
  • Corolla AE86 GT-S – RWD
  • Corolla AE82 FX-16 – FWD
  • Corolla AE92 GT-S – FWD
  • SE Sedan (North America): (RWD from 1983-87 and FWD from 1988-91)
  • Some Celicas

Other models equipped with the 4A-GE:

  • Chevrolet Nova (based on Toyota AE82 chassis; 1984-1988– These 4A-GE cars were exceptionally rare) * Geo Prizm GSi (based on Toyota AE92 chassis; 1990-1992)


  • Engine displacement – 1.6 litres (1587 cc)
  • Layout – DOHC Inline-4 (Straight-4)
  • Valves – 16, 4 per each cylinder
  • Power – 115-140 hp (96-103 kW) @ 6600 rpm
  • Torque – 109 lbf.ft (148 N·m) @ 5800 rpm
  • Redline – 7600 rpm
  • Fuel Delivery System – MPFI

Toyota sponsored the Champ Car Atlantic Championship from 1990 to 2005. A kit version of the 4A-GE from Toyota Racing Development was used to power Formula Atlantic cars during this period. This engine used a modified 16-valve head and produced approximately 240 horsepower at 8400 rpm.

4AGE 20v

A special 4A-GE was produced from 1991 through 1998 to replace the 4A-GZE. It was a naturally-aspirated engine with an additional intake valve for each cylinder, making it one of the first production 5-valve engines in history. These generation engines also featured quad throttle bodies. The engine can be recognized by its silver or black top. This was the last of the 4A family to be produced. Toyota VVT was used for 160–165 hp (123–127 kW) at 7800 rpm and 120 ft·lbf (162 N·m) at 5600 rpm, quite impressive for a naturally-aspirated 1.6 L engine. Note that although VVT was present in the silver top and the black top 4A-GE, VVT-i was not available.

  • 1992 Toyota Corolla (AKA Toyota Levin) AE101 (silver-top) All GT models (GT Apex GT-V etc)
  • 1995 Toyota Corolla (AKA Toyota Levin) AE111 (black-top) All BZ models (BZG, BZR, BZV etc)

The 4A-GZE (produced in various forms from 1986 through 1995) was the supercharged version. Based on the same block and head, the 4A-GZE was equipped with a roots-type supercharger and therefore the compression ratio, valve timing and ports were modified. It was used in the North American supercharged Toyota MR2, rated at 145 hp (108 kW) and 140 ft·lbf (190 N·m). Later versions of this engine are rated 170 hp (127 kW) and 155 ft·lbf (210 N·m) for the AE92 and AE101 Corolla.
