intake manifold with long runners joined to a small displacement plenum and other changes. Even though the valve angle is closer to what is considered in some racing circles to be ideal for power (approximately 25 degrees), its other design differences and the intake which is tuned for a primary harmonic resonance at low RPM means that it has about 10% less power compared to the 4A-GE engine. This engine design improves fuel efficiency and torque, but compromises power. Power ratings varied from in the US market.

Called an EFI-S engine. Output: at 6,000 rpm and at 4,800 rpm (compression at 9.5:1) Applications: AT171 Carina 1990–1992 (Japan only) AE95 Sprinter Carib 1990–1995 (Japan only) 4A-GE (16-valve) The cylinder head was developed by Yamaha Motor Corporation and was built at Toyota's Shimoyama plant alongside the 4A and 2A engines. 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. New performance parts are still available for sale even today because of its strong fan base. 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 2000. First Generation "Blue Top" (Early Bigport) The first-generation 4A-GE which was introduced in May 1983 replaced the 2T-G as Toyota's most popular twincam engine. This engine was identifiable via silver cam covers with the lettering on the upper cover painted black and blue, as well as the presence of three reinforcement ribs on
