This helps in achieving a decent fuel economy for its time, typically around 22 mpg in the city and 28 mpg on the highway. For a car designed to handle both on-road and off-road conditions, these figures were quite respectable. The EJ22 engine also boasts a robust cast-iron block and aluminum alloy cylinder heads, which enhance its durability and heat dissipation. This combination allows the engine to withstand the rigors of daily driving and occasional off-road adventures without compromising performance or reliability. Overall, the 2.2-liter SOHC EJ22 engine in the 1999 Subaru Outback Sport is a well-engineered and dependable powerplant that has stood the test of time. Its balanced performance, reliability, and unique boxer configuration make it a significant part of Subaru's automotive history.

Performance and Handling

When we talk about the performance and handling of the 1999 Subaru Outback Sport, it's more than just raw horsepower figures. The car’s symmetrical all-wheel-drive system, combined with the boxer engine, created a unique driving experience. The symmetrical all-wheel-drive ensures that power is distributed evenly to all four wheels, providing excellent traction and stability, especially in slippery conditions. This makes the Outback Sport a capable performer in snow, rain, and even light off-road situations. The car's handling is further enhanced by its fully independent suspension system, which provides a smooth and controlled ride. The suspension soaks up bumps and imperfections in the road, while also minimizing body roll during cornering. This makes the Outback Sport feel planted and confident, even on winding roads. The combination of the boxer engine and the all-wheel-drive system also contributes to the car's balanced weight distribution, which further improves its handling characteristics. The car feels nimble and responsive, making it enjoyable to drive in a variety of conditions. While the 137 horsepower might not set any records, it is more than adequate for everyday driving. The engine provides enough power for confident acceleration and passing maneuvers, while also maintaining decent fuel economy. The car's five-speed manual transmission allows drivers to extract the most out of the engine's power band, providing a more engaging driving experience. The automatic transmission, while not as sporty, still provides smooth and predictable shifts. Overall, the 1999 Subaru Outback Sport offers a well-rounded driving experience that prioritizes stability, traction, and control. Its unique combination of the boxer engine, symmetrical all-wheel-drive, and independent suspension makes it a capable and enjoyable car to drive in a variety of conditions.

Reliability and Maintenance

Regarding the reliability and maintenance of the 1999 Subaru Outback Sport engine, the EJ22 is generally considered a reliable engine, but like any engine, it has its quirks. Regular maintenance is key to keeping it running smoothly. Oil changes should be done every 3,000 to 5,000 miles, depending on driving conditions and the type of oil used. It’s also important to check the coolant level regularly, as the boxer engine design can be sensitive to overheating if the coolant is low. One common issue with the EJ22 engine is head gasket failures. This is often caused by overheating or age, and it can lead to coolant leaks, oil consumption, and decreased engine performance. If you notice any signs of head gasket failure, such as white smoke from the exhaust or a milky substance on the oil dipstick, it’s important to address the issue promptly to prevent further damage. Another potential issue is oil leaks, which can occur from various seals and gaskets around the engine. Regular inspections can help identify and address these leaks before they become major problems. The timing belt is another critical component that needs to be replaced at regular intervals, typically every 60,000 to 100,000 miles. A broken timing belt can cause severe engine damage, so it’s important to adhere to the recommended replacement schedule. Despite these potential issues, the EJ22 engine is generally robust and can last for many years with proper care and maintenance. Regular maintenance, timely repairs, and attention to potential warning signs can help ensure that your 1999 Subaru Outback Sport engine continues to perform reliably for years to come. By staying proactive with maintenance and addressing any issues promptly, you can keep your Outback Sport running smoothly and enjoy its unique driving experience for many years.

No car is perfect, and knowing what to look out for can save you a lot of headaches down the road. One of the most well-known issues with the EJ22 engine, as mentioned earlier, is head gasket failure. This can be a costly repair, but there are some preventative measures you can take. Ensure your cooling system is in good condition, use a high-quality coolant, and avoid overheating the engine. If you suspect a head gasket issue, get it checked out by a mechanic ASAP. Another common problem is oil leaks. These can occur from various places, such as the valve cover gaskets, oil pan gasket, and rear main seal. Regularly inspect your engine for oil leaks, and address them promptly to prevent them from getting worse. Replacing gaskets and seals is a relatively straightforward repair, but it's important to use high-quality parts to ensure a long-lasting fix. The exhaust system can also be prone to rust and corrosion, especially in areas with harsh winters. Inspect your exhaust system regularly for any signs of rust or leaks, and replace any damaged components as needed. A faulty exhaust system can affect engine performance and fuel economy, so it's important to keep it in good condition. The electrical system can also experience issues, such as faulty sensors and wiring problems. These can cause a variety of symptoms, such as poor engine performance, warning lights, and starting problems. Diagnosing electrical issues can be tricky, so it's often best to take your car to a qualified mechanic for diagnosis and repair. By being aware of these common issues and taking proactive steps to address them, you can keep your 1999 Subaru Outback Sport running smoothly and reliably for many years.

Upgrades and Modifications

For those of you who love to tinker, let's talk about upgrades and modifications for the 1999 Subaru Outback Sport engine.
