Toyota Car Parts - A Series Engines

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 The 4A-F used a carburetor, while the 4A-FE used electronic fuel injection system (notice the 'E') Power output ranged from just 62 hp (46 kW) at 4800 rpm all the way to 90 hp (67 kW) at 6000 rpm The engine was used in the Toyota Corolla Sedan from 1988 to 1998 and in the 5th Generation Celica ST models from 1989 to 1993 both in North America and Europe, as well as the Camry from '87 to '91 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 All 4A engines have a displacement of 1·6 L (1587 cc) 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 Only the AE86 version carried the 4A-GE engine and GT-S designations in the US In other markets, other designations were used The series began in the late 1970s with the 1A, an SOHC engine with a displacement of 1. Additional engine modifications to extend life and the reliability included under piston cooling oil squirters, thicker connecting rods and other components 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 Cylinder bore was 77·5 mm (3·05 in) and stroke was 77 mm (3·03 in). The A Series engines are a family of straight-4 internal combustion engines with displacement from 1·3 L to 1·8 L produced by Toyota Motor Corporation. 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 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 The first-generation 4A-GE which was introduced in 1983 replaced the 2T-G in most applications 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 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 To compansate for the reduced air speed the first-generation engines included the TVIS feature, in which dual intake runners are fitted with butterfly valves that opened at approximetly 4200 RPM While the port cross section was suitable for a very highly modified engine at very high revs it caused a considerable drop in low down torque due to the decreased air speeds at those revs The 4A-FE is basically the same as the 4A-F (introduced in the previous generation of Corollas), the most apparent difference being the fuel delivery system A kit version of the 4A-GE from Toyota Racing Development was used to power Formula Atlantic cars during this period The second generation engine was produced from 1992 until 1998 An AE85 chassis code may be a base model Corolla, or an SR-5, with a 4A-C engine Cylinder bore was 76 mm (2·99 in) and stroke was 71·4 mm (2·81 in). 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) Also, the 4A-FE had extra power The 1·5 L (1452 cc) 1A was produced in 1978 and 1979. It was a 2-valve SOHC design like its predecessor. 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' Toyota models that had this engine:
Corolla AE85 (JDM)
Carina AA60The 4A was produced from 1980 through 1998. New performance parts are still available for sale even today because of its strong fan base This engine has the silver cam covers with the words only written in red, hence the nickname 'red top' Toyota joint venture partner Tianjin FAW Xiali still produces 1·3 L 8A and recently restarted production of the 5A. 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 It was a 2-valve SOHC 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 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. Toyota designed the engine for performance; the valve angle was a relatively wide 50 degrees, which at the time was believed to be ideal for high power production The first generation 4AGE is nicknamed the 'bigport' engine because it had inlet ports of a very large cross sectional area 5 L. 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 The second is that it employed a 'slave cam system', the camshafts being geared together and driven off one camshaft's sprocket (both camshafts' sprockets on the G-Engine are rotated by the timing belt). The series has cast iron engine blocks and aluminum cylinder heads. The first- and second-generation engines are very popular with racers and tuners because of the ease of modification, simple design, and lightness Numerous variations of the basic 4A design were produced, from SOHC 2-valve all the way to DOHC 5-valve versions. Torque was less spread from 75 ft·lbf (101 N·m) at 2800 rpm to 89 ft·lbf (120 N·m) at 4000 rpm. The first obvious difference are the valves, the engine's intake and exhaust valves were placed 22. In between, many interesting variations were produced, including one of the first 5-valve engines (the 4A) and the 170 hp (127 kW) supercharged 4A-GZE. 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 1·3 L (1295 cc) 2A was produced from 1979 through 1986. The engine was succeeded by the 3ZZ-FE, a 1·6-liter engine with VVT-i technology. The next major modification was the high-performance 4A-G, with the fuel injected version, the 4A-GE, being the most powerful. 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 only exception was the US-market 1990-91 Geo Prizm GSi, which was equipped with the MAP.
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) The TVIS feature is maintained.
