The Toyota 4A-GE is a family of 1.6-liter DOHC engines, not one fixed specification: the AE86-era version was a 16-valve design, while a later version added five valves per cylinder and other features. Toyota’s records document the engines’ development, applications, and published output figures, but those figures vary by model and rating context.
1. The AE86 record identifies its engine as a 4A-GEU
Toyota’s record for the Japanese Corolla Levin GT APEX and GTV identifies the AE86’s engine as the 4A-GEU. It lists a 1,587 cc water-cooled inline-four with double overhead camshafts. Toyota gives a representative rating of 130 PS at 6,600 rpm and labels it a gross figure.

2. The early 4A-GE had 16 valves
Toyota UK describes the initial 1.6-liter 4A-GE as a DOHC engine with a 16-valve head. That early layout is distinct from the five-valve design Toyota introduced later; “4A-GE” refers to an evolving family rather than a single unchanged engine specification.
3. Toyota says the engine’s development changed direction
According to Toyota UK’s historical account, the engine was originally designed as a single-overhead-cam unit to replace the 2T-GEU. Eighteen months into development, Toyota converted the design to DOHC with a 16-valve head. This is Toyota UK’s account of the development history.

4. Toyota called the early engine LASRE
Toyota UK expands LASRE as “Lightweight Advanced Super Response Engine.” The name is useful historical context, but it should not be taken to mean that every later 4A-GE version used identical hardware.
5. The five-valve engine was a 1991 milestone
Toyota’s 75-year history describes the five-valve 4A-GE as the company’s first five-valve sports engine. Toyota says it was adopted in the Corolla Levin and Sprinter Trueno with the 1991 Corolla model change. That milestone applies to the five-valve version, not the beginning of the entire 4A-GE family.
6. The later engine used three intake valves and two exhaust valves per cylinder
Toyota’s 1991 announcement says the new engine used five valves per cylinder: three intake and two exhaust. Toyota said the arrangement aimed to improve intake and exhaust efficiency.
7. Toyota rated the later 1.6-liter engine at 160 PS
In its 1991 model-change announcement, Toyota listed the later 1.6-liter 4A-GE at 160 PS at 7,400 rpm. This is a manufacturer-published period specification, not a modern independent test.
8. The later engine was naturally aspirated
Toyota described the later engine as achieving 100 PS per liter “without turbo-or supercharging.” That wording describes the naturally aspirated engine in the 1991 announcement; it should not be read as a rating for every 4A-GE version.
9. Individual throttles and two-step intake timing were among its features
Toyota’s 1991 specification lists individual cylinder throttles and two-step variable intake-valve timing. The announcement describes the timing mechanism as controlling intake-valve opening and closing according to driving conditions. It does not describe the system as continuously variable.

Toyota’s records include different figures for different applications and rating contexts. The AE86 record lists 130 PS at 6,600 rpm as a gross figure; Toyota’s AE101 lineage record lists 160 PS at 7,400 rpm as a net figure. These are not a controlled comparison, and neither number should be presented as the output of every 4A-GE.
| Version or record | Documented details | Output and rating context |
|---|---|---|
| AE86 Corolla Levin record | 4A-GEU; 1,587 cc; DOHC 16-valve engine | 130 PS at 6,600 rpm, gross |
| 1991 five-valve 4A-GE announcement | 1.6-liter; three intake and two exhaust valves per cylinder; individual cylinder throttles; two-step variable intake-valve timing | 160 PS at 7,400 rpm |
| AE101 Corolla Levin lineage record | 1,587 cc | 160 PS at 7,400 rpm, net |

What is a Toyota 4AGE engine?
It is a family of Toyota 1.6-liter DOHC engines. Versions differ in valve count, features, applications, and published specifications.
What is the difference between a 16-valve and 20-valve 4AGE?
The early design had 16 valves. Toyota’s later five-valve version had three intake and two exhaust valves per cylinder, for 20 valves total, and included individual cylinder throttles and two-step variable intake-valve timing.
How much power does a 4AGE make?
It depends on the version and the rating context. Toyota lists 130 PS at 6,600 rpm gross for the AE86 4A-GEU record and 160 PS at 7,400 rpm for the later five-valve engine; Toyota’s AE101 record labels its 160 PS figure net.
Which cars came with a 4AGE?
Toyota records identify the AE86 Corolla Levin GT APEX and GTV with the 4A-GEU. Toyota also says the five-valve 4A-GE was adopted in the Corolla Levin and Sprinter Trueno with the 1991 Corolla model change. Check the specific model, market, and engine code when identifying a car.
