How Long Does A Toyota 22RE Engine Last?

Last Updated on September 10, 2022 by John K. Clifford

The 22 RE is arguably the most reliable engine that Toyota ever made. It succeeded the 22R, the longest-running and most popular engine in the automaker’s history. These engines were available in different configurations and can last over 300,000 miles without issues. Some drivers have reported getting over 350,000-400,000 miles on them with no trouble. 

The 22RE engine was introduced in 1982 and was used in vehicles ranging from Sport utility vehicles to half-ton pickups. It was a fuel-injected version of the 22R four-cylinder engine. When it was first developed, it produced 105 horsepower at 4,800 RPM; the engine had a displacement of 2366 cc and achieved maximum torque of 137 lb./ft at 2800RPM. The compression on the engine was 9.3 to 1, with a bore of 92mm and a stroke of 89mm.

 After three years, the engine was upgraded to make it more powerful. It now had a maximum horsepower of 112 at 4600 RPM. Maximum torque also went up to 142 at 3400RPM. The displacement and compression remained the same. This engine didn’t have an astonishing power to weight ratio, but it was valued for its reliability and endurance. It was used in various models such as the 4Runner (1985-1995), pickup (1984-1995), Toyota Hilux (1984-1995), Toyota Celica (1983-1985), Toyota corona RT142(1983-1985), and the Volkswagen taro (1989-1997)

Every driver wants their car to drive smoothly from one point to another and not have engine issues. Nobody wants to spend hours in the car repair shop or garage dealing with engine problems. The 22RE engine gives drivers exactly what they want by ensuring it is highly durable and reliable.

The original 22RE had a cast-iron block and soft piston rings that contributed immensely to the long lifespan of the motor. The piston rings allowed cylinder bores to escape from ridges as the motor works. The valvetrain features a traditional pushrod system with a camshaft in the block. Each of the four cylinders had one intake and one exhaust valve making them 8 in total.

The production of the 22RE motor ceased in 1997, but many of the 22RE motors are still in good condition and utilized for automobiles. The engine can run for 300,000 to 350,000 or 400,000 miles without issues. Some drivers have also reported going above these miles with fantastic lifespans.

Five Ways You Can Upgrade Performance On 22RE Engine

 Performance On 22RE Engine

Are you looking to upgrade the performance and internal engine of your 22RE? Below are some sure ways to get more HP and a smoother ride on any 22RE engine.

1. Header. A header known as the exhaust manifold is one of the most affordable yet valuable bolt-on performance upgrades for your 22R series engine.

2. As a complement to the header upgrade, a Cold Air Intake kit comes in handy. As their name suggests, these kits bring cooler air into the engine and combustion chamber to boost efficiency and engine power. Colder air has a high oxygen density, meaning more oxygen will be included in the same cold air volume than warm air. Due to high oxygen, the combustion reaction will be more effective, thus giving off greater mileage and more engine power.

3. Install a cylinder head cylinder heads play a major role in your engine; they hold the valves and fuel injectors and control airflow in and out the cylinders and fuel deployment.

4. Electric Fan Kit.

An electric fan system ensures an efficient flow of air and optimizes the heat exchange to the radiator. Electric fan kits improve fuel economy by more than 18 percent and also lowers emissions 

5. A larger Throttle Body.

Larger throttle bodies can be used to boost overall horsepower and also increase acceleration performance. They work by delivering air at a higher rate than the stock engine, thus allowing the driver to feel an accelerating response from the vehicle sooner.

You can also consider installing LC Engineering’s Turbo Kits on the Toyota 22RE-powered vehicles, including trucks, 4Runners, and Celica. But for this high-boost setup, we highly recommend your engine is prepared and set up to handle boost before adding a turbocharger kit. The largest factor to have in mind should be a Lower compression of (9:1 or less)

Tips To Prolong The Lifespan Of Your Toyota 22RE Engine
