Toyota Car Parts - A Series 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 in to other Toyota cars such as the KE70 and KP61 Power was also extremely varied, from 70 hp (52 kW) at 4800 rpm in the basic California-spec 4A-C to 170 hp (127 kW) at 6400 rpm in the supercharged 4A-GZE The effect was that at lower revs where the airspeed would normally be slow, four of the eight runners were closed, this forced all the engine to draw in all its air through half the runners in the manifold 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 Corollas/Sprinters were all based around the FF layout Applications:
1992 Toyota Corolla Levin, Sprinter Trueno AE101 (silver top): All GT models (GT Apex, GT-V etc)
1995 Toyota Corolla Levin, Sprinter Trueno AE111 (black top): All BZ models (BZG, BZR, BZV etc) Toyota sponsored the Champ Car Atlantic Championship from 1990 to 2005 This change in the intlet ports negated the need to have the need for the earlier twin runner manifold and was replaced with a single runner manifold The difference between the two generations of this engine can be identified by the external shape of the engine, the first generation (1987–1993) have a more rugged look, a plate on the head which read '16valve EFI', and the fuel injectors in the head A kit version of the 4A-GE from Toyota Racing Development was used to power Formula Atlantic cars during this period The first generation 4AGE is nicknamed the 'bigport' engine because it had inlet ports of a very large cross sectional area During rising engine speed, a slight lurch can occur at the crossover point and an experienced driver will be able to detect the shift in performance All 4A engines have a displacement of 1·6 L (1587 cc) The 4A-GE was one of the earliest inline-4 engines to have both a DOHC 16 valve configuration (four valves per cylinder, two inlet, two exhaust) and electronic fuel injection (EFI) New performance parts are still available for sale even today because of its strong fan base Clarification: In the US market, the 4A-GE engine was first used in the 1985 model year Corolla GT-S only, which is identified as an 'AE88' in the VIN but uses the AE86 chassis code on the firewall as the AE88 is a 'sub' version of the AE86 Although both have the same displacement and are DOHC, they were optimized for different uses The second generation had a higher profile cams design in the head, the cam cover having ribs throughout its length and the injectors in the intake manifold runners Toyota models that have had this engine:
Toyota MR2 AW11: Mid-engine RWD
Corolla AE85/AE86 GT-S: RWD (often referred to as generic AE86 chassis group)
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 Power output ranged from just 62 hp (46 kW) at 4800 rpm all the way to 90 hp (67 kW) at 6000 rpm. This engine has the silver cam covers with the words only written in red, hence the nickname 'red top' Also, the 4A-FE had extra power An AE85 chassis code may be a base model Corolla, or an SR-5, with a 4A-C engine To correct the air-speed problems of the earlier genrations of engine the heads inlet ports were redesigned to have smaller cross section inlet ports, and hence has been nickanmed as the 'smallport head' The use of an air flow meter (MAF) sensor, which restricted air flow slightly but produced cleaner emissions that conformed to the US regulations, limited the power to 112 hp whereas the Japanese model — which used a manifold absolute pressure (MAP) sensor — produced 130 PS (96 kW) The 1·5 L (1452 cc) 1A was produced in 1978 and 1979. The engine was succeeded by the 3ZZ-FE, a 1·6-liter engine with VVT-i technology It was extremely light and strong for a production engine using an all-iron block, and produced 112 hp (84 kW) at 6600 rpm and 97 ft·lbf (131N·m) of torque at 4800 rpm in the American market There were California-spec (3A-C), Japan-spec (3A-U), transverse (3A-L), and swirl-intake (3A-S) versions of the same basic design. It is speculated that the 4A-GE is actually a road-going version of the Ford Cosworth BDA racing engine, reverse engineered by Toyota as the bore and stroke dimensions are similar and there are many similarities in the engine design, making it a reliable engine for motorsports applications Toyota models that had this engine:
Corolla AE85 (JDM)
Carina AA60The 4A was produced from 1980 through 1998. The first- and second-generation engines are very popular with racers and tuners because of the ease of modification, simple design, and lightness The only exception was the US-market 1990-91 Geo Prizm GSi, which was equipped with the MAP Toyota engineers had skillfully optimized the power and torque from the company's relatively low-displacement engines Much confusion exists, even among dealers, as to which models contained what equipment, especially since Toyota split the Corolla line into both RWD and FWD versions, and the GT-S designation was only well known as a Celica version at that time The series began in the late 1970s with the 1A, an SOHC engine with a displacement of 1. The 4A-GE engines for the 1985 model year are referred to as 'blue top' as opposed to the later 'red top' engines, because the paint color on the valve covers is different, to show the different engine revision, using different port sizes, different airflow metering, and other minor differences on the engine Production of the various models of this version lasted for five generations, from 1983 through 1991 for 16-valve versions and the 5-valve 4A-GE lasted through 1998. Production of the first-generation engine model lasted through 1987 The first-generation 4A-GE which was introduced in 1983 replaced the 2T-G in most applications. 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 The 1·3 L (1295 cc) 2A was produced from 1979 through 1986. Toyota designed this engine with fuel economy in mind. It is visually similar to the first-generation engine and the power output is unchanged, but the upper cam cover now featured red and black lettering It was a 2-valve SOHC design like its predecessor. The 1987–1998 4A-FE is the descendant of the carbureted 4A-F. 5 L. It was a 2-valve SOHC engine. The second-generation 4A-GE produced from 1987 to 1989 featured larger diameter bearings for the con-rod big ends (42mm) and added four additional reinforcement ribs on the back of the engine block, for a total of seven. 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 the back side of the block. 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 revs means that it has about 20% less power compared to the 4A-GE. The 4A-GE was first introduced in the 1983 Sprinter Trueno AE86 and the Corolla Levin AE86 sports version This enabled the the torque curve to still be intact at lower engine speeds, allowing for better performance across the entire speed band and a broad, flat torque curve around the crossover point. This version, although from the same series and the same generation as the 4A-GE, is different from its 'brother' in terms of performance and power. This engine revision upped the power to 138 hp (103 kW) at 7200 rpm with a torque of 110 ft·lbf (149 N·m) at 4800 RPM. The first obvious difference are the valves, the engine's intake and exhaust valves were placed 22. The third-generation appeared in 1989 and was in production until 1991. The next major modification was the high-performance 4A-G, with the fuel injected version, the 4A-GE, being the most powerful. The plus side of this design is that it improved fuel efficiency and torque, the down side is that it compromises power.
