Toyota Car Parts - A Series Engines

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 An AE85 chassis code may be a base model Corolla, or an SR-5, with a 4A-C engine 5 L 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 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 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 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 Numerous variations of the basic 4A design were produced, from SOHC 2-valve all the way to DOHC 5-valve versions 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 The 1987–1998 4A-FE is the descendant of the carbureted 4A-F Torque was less spread from 75 ft·lbf (101 N·m) at 2800 rpm to 89 ft·lbf (120 N·m) at 4000 rpm Toyota increased the compression ratios from 9·4:1 to 10·3:1 It was a 2-valve SOHC engine. 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 Additional engine modifications to extend life and the reliability included under piston cooling oil squirters, thicker connecting rods and other components 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 next major modification was the high-performance 4A-G, with the fuel injected version, the 4A-GE, being the most powerful 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 generation 4AGE is nicknamed the 'bigport' engine because it had inlet ports of a very large cross sectional area All 4A engines have a displacement of 1·6 L (1587 cc). 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 Although not as powerful as the 4A-GE, both engines are renowned for the power they produce from such a low displacement (relative to other engines) Toyota models that had this engine:
Corolla AE85 (JDM)
Carina AA60The 4A was produced from 1980 through 1998. 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 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 The plus side of this design is that it improved fuel efficiency and torque, the down side is that it compromises power Output ranged from 65–75 hp (48–56 kW) at 5400–6000 rpm and 72–79 ft·lbf (97–107 N·m) at 3600 rpm. New performance parts are still available for sale even today because of its strong fan base There were California-spec (3A-C), Japan-spec (3A-U), transverse (3A-L), and swirl-intake (3A-S) versions of the same basic design. The 1·3 L (1295 cc) 2A was produced from 1979 through 1986. It was a 2-valve SOHC design like its predecessor. 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 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 Cylinder bore was 76 mm (2·99 in) and stroke was 71·4 mm (2·81 in). Power rating varies during certain generations that had the engine. 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 engine was succeeded by the 3ZZ-FE, a 1·6-liter engine with VVT-i technology. The third-generation appeared in 1989 and was in production until 1991 Also, the 4A-FE had extra power. The 4A-GE was first introduced in the 1983 Sprinter Trueno AE86 and the Corolla Levin AE86 sports version All non-US market 4A-GEs continued to use a MAP sensor, while all of the US-market Toyota 4A-GE came with a MAF sensor The 4A-F used a carburetor, while the 4A-FE used electronic fuel injection system (notice the 'E'). 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 It was a 2-valve SOHC like the 1A and 2A. 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). Only the AE86 version carried the 4A-GE engine and GT-S designations in the US In other markets, other designations were used 3° apart (compared to 50° in the G-Engines). The series began in the late 1970s with the 1A, an SOHC engine with a displacement of 1. Production of the first-generation engine model lasted through 1987. 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. 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. This raised the airspeed which caused better cylender filling and also better fuel atomisation. 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. This engine has the silver cam covers with the words only written in red, hence the nickname 'red top'. 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. Also of note the pistons were changed to accept a 20mm fully floating gudgen pin unlike the 18mm pressed in pins of the earlier versions.
