Engine Bay - Toyota Type 4AGE

The reliability and performance of these engines has earned them a fair number of enthusiasts and a fan base as they are a popular choice for an engine swap into other Toyota cars such as the KE70 and KP61. Production of the various models of this version lasted for five generations, from May 1983 through 1991 for 16-valve versions and the 20-valve 4A-GE lasting through 1998.
The 4A-GE 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 was produced and all future Corollas/Sprinters were based around the FF layout. The AW11 MR2 continued use of the engine as MR layout, transversely mounted midship. 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 to 1992. All 4A-GE engines (including the 20-valve versions below) feature a forged crankshaft rather than a cheaper and more commonly used cast version.
