Toyota A engine

Bdc: started summary. will continue later.

Toyota's A-series of inline four-cylinder motors was produced from the late 1970s until the early 2000s. It was used primarily in Corolla-platform cars, but also powered certain Tercels, MR2s, and Celicas, as well as Corollas sold as rebadged GM vehicles (Geo Prizm and Chevy Nova). All A-series motors have cast-iron blocks and aluminum alloy heads. The 4A-C (carbureted 1.6l) 4A-FE (EFI 1.6l) and 7A-FE (EFI 1.8l) were the bread-and-butter Corolla motors from the early 1980s until the late 1990s when the A series was replaced by the ZZ series. Yamaha developed the cylinder heads for the 4A-GE and 4A-GZE, which were used in high-performance cars such as the Corolla GT-S and MR2.

==Most Common Versions==
The A-series motor was produced in huge quantities from 1978 to 2003 and was sold in ever. The most common versions are listed below.

* 3A-U: SOHC 8-valve carbureted 1.5l used primarily in Japan-only models. Produced between 1979 and 1988 and generated 52 to 66 kW, depending on version. 1452cc, 77.5mm bore x 77mm stroke
* 4A-C: SOHC 8-valve carbureted 1.6l used in the Corolla in most markets. Produced from 1980-1986. All 4A motors have 1587cc displacement, 81mm bore and 77mm stroke.
* 4A-FE: Fuel-injected, 16-valve version of the 4A-C. This also had two overhead cams, slaved together and driven by one timing pulley. Sold from 1987 to 1998 in several iterations; rated at 105hp throughout its lifetime but later versions (which used MAP load sensing instead of the flapper-door airflow meter) are rumored to make slightly more power.
* 4A-GE (16 valve): This was the high-performance A-series engine. Dual overhead cams, 16 valves, a 7500rpm redline, and Toyota reliability made this engine a hit with enthusiasts. First sold in the 1983 Corolla GT-S and later the 1985 MR2. Received several updates throughout the years, including cylinder head and compression changes in 1990 (130hp SAE rating for 1990-91 Corolla GT-S/Geo Prizm) and a new 20-valve cylinder head in 1992 for overseas markets only. This 20-valve version revved to 8200 RPM and had individual throttles, high compression, and a basic cam-phasing VVT system, and generated 155PS from 1992-94 and 165PS from 1995-1998.
* 4A-GZE: This was basically just a supercharged version of the 16-valve 4A-GE. It was only sold in 1988 and 1989 MR2s in the US, as well as some FWD Corollas from 1988 to 1994 in overseas markets. 1988-1989 models produced 145hp and 140 lb-ft with a strong torque band that, combined with the extreme straight-line traction of the 1988 MR2, made it one of the fastest cars from 0-60 in the late 1980s. In 1990 the supercharged motors were also updated with smaller intake ports, higher compression, and more boost, with higher horsepower ratings (165PS from 1990-91, 170PS from 1992-94).
* 7A-FE: A 1.8l version of the basic Corolla motor, sold as an option to 1992+ Corollas and was also the base motor for 1994-1997 Celicas. It has the same narrow-angle slave-DOHC cylinder head of the 4A-FE motor and is rated at 105-115hp in America depending on the model. Some enthusiasts adapt a 4A-GE cylinder head to a 7A-FE block to make a "7A-GE" which has the same high-revving characteristics of the 4A-GE with a 200cc increase in displacement.

==Unique Attributes==
The 4A-GE was the first mass-produced DOHC, four-valve-per-cylinder motor.
