Toyota 4AGe engine Great condition

The Toyota 4A-GE is a classic, high-revving, 1.6-liter four-cylinder engine produced from 1983 to 1998, known for its dual-overhead-cam, four-valve-per-cylinder design, with the cylinder head co-developed with Yamaha. It was a popular performance engine found in models like the AE86 Corolla and MR2, valued for its high-revving capabilities and distinctive sound. While a capable engine for its era, it was often modified for racing and performance applications, with various generations offering different strengths and weaknesses for tuning.

Key Characteristics:

Engine Type: 1.6-liter, four-cylinder, dual-overhead-cam, four-valve.
Performance Focus: Designed for high-revving performance rather than low-end torque.
Yamaha Collaboration: The performance cylinder head was developed in collaboration with Yamaha Motor Corporation.
Electronic Fuel Injection (EFI): Featured electronic fuel injection, which was advanced for mass-produced engines of its time.
Legendary Status: Gained legendary status in racing, particularly in Formula Atlantic, for achieving high horsepower for its displacement.

Common Applications: Toyota Corolla AE86 (its first generation), Toyota Celica, Toyota MR2, and Gea Prism and Chevrolet Nova (rebadged Toyotas).

Legacy and Tuning:

Versatile Platform:

The 4A-GE is a highly tunable engine, with decades of modifications.
Evolution:

The engine went through multiple generations, with significant improvements in later models, such as larger rod journals and external reinforcements.
Popular Modifications:

Modifications include turbocharging, supercharging (the factory “4AGZE”), and naturally aspirated upgrades like individual throttle bodies and aggressive camshafts.
Enduring Appeal:

Despite its age, it remains a popular choice for engine swaps and performance builds due to its availability, reliability, and the fun factor of working with it.

The Toyota 4A-GE engine is a 1.6L (1587cc) DOHC inline-4 engine, known for its high-revving performance and 4-valve-per-cylinder design. Key specifications include a bore and stroke of 81 mm x 77 mm and a Toyota Variable Intake System (TVIS) in earlier models. Power output varied by generation but typically ranged from around 115 to 128 hp, with later 20-valve versions producing more, reaching up to 160 hp or higher.

General Specifications

Configuration: DOHC Inline-4
Displacement: 1.6 L (1,587 cc)
Bore: 81 mm
Stroke: 77 mm
Valves: 16-valve or 20-valve (5 per cylinder)
Fuel System: Multi-Point Fuel Injection (MPFI)

Performance & Features

Power:

Ranges from approximately 115-128 hp (117-130 PS) in 16-valve models, with later 20-valve engines achieving higher outputs.
Torque:

Varies by generation, with earlier models producing around 148 N⋅m (109 lb-ft).
Redline:

High redline, often around 7,600 rpm.
TVIS:

The Toyota Variable Intake System was used on earlier 4A-GEs, employing butterflies to alter intake port geometry for improved low-end torque and high-end performance.
20-Valve Heads:

Later generations, such as the “Silver Top” and “Black Top” engines, featured 20 valves per cylinder for enhanced performance.

Common Applications

The 4A-GE was a popular engine in various Toyota models:

Toyota Corolla: AE86/AE82
Toyota Sprinter Trueno
Toyota MR2: AW11
Toyota Celica: AA63

Key Variations

16-Valve: The original 4A-GE featured a 16-valve cylinder head and often incorporated the TVIS.
20-Valve: Later versions, known as the 4A-GE 20V, introduced three intake valves per cylinder and could have more features like a distributor mounted on the exhaust cam.
4AGZE: A supercharged variant of the 4A-GE engine.
