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

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 of 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

Most drivers who have had the 22RE engine have reported hitting high mileage of 300,000 miles and above. You can get this mileage and even better when you take good care of your engine. Below are some tips that will help you extend the lifespan of your 22RE engine and any other Toyota engine:

1. Always follow the recommended maintenance schedule

2. Ensure you check oil and coolant levels regularly

3. Replace spark plugs and timing belts

4. Clean air filters at close intervals

5. Check for leaks or cracks and have them handled as soon as possible

6. Replace fuel filters as needed

7. Never ignore the ‘check engine light.’

8. Tune-up carburetors at regular intervals

9. avoid harsh driving 

10. for any engine service and repair, only use qualified and certified mechanics; the wrong mechanic can cause irreparable damage to your engine

11. immediately after starting the vehicle, keep revolutions per minute low for about 20 minutes

12. refill gas at reputable gas stations to avoid buying gas that may damage your engine’s components.
