Subaru WRX: A Comprehensive Guide
The Subaru WRX is a legendary all-wheel-drive sport compact car with a rich history in rally racing and a dedicated following among automotive enthusiasts. This guide provides a comprehensive overview of the WRX, from its history and evolution to common issues and performance tuning.
History & Evolution
The Subaru WRX (World Rally eXperimental) was first introduced in 1992 as a high-performance version of the Impreza. It quickly gained a reputation for its turbocharged boxer engine, all-wheel-drive system, and rally-inspired performance. Over the years, the WRX has evolved through several generations, each with its own unique characteristics and improvements.
- First Generation (1992-2000): The original GC8 WRX set the standard for the model, with its lightweight chassis and potent performance.
- Second Generation (2000-2007): The "New Age" Impreza WRX, known for its distinctive "bugeye," "blobeye," and "hawkeye" headlight designs, brought significant improvements in refinement and power.
- Third Generation (2007-2014): The WRX became a separate model from the Impreza, with a more mature design and a focus on improved handling and daily drivability.
- Fourth Generation (2014-2021): The VA WRX introduced a new direct-injected FA20F engine and a more aggressive design.
- Fifth Generation (2022-Present): The latest VB WRX features a new 2.4L turbocharged engine and a more modern design, though it has been met with mixed reviews from enthusiasts.
Common Issues
While the WRX is a reliable vehicle, it is not without its common issues. Some of the most frequently reported problems include:
- Ringland Failure: A common issue on the EJ-series engines, particularly with modified vehicles.
- Head Gasket Failure: Another common issue on the EJ-series engines, especially on high-mileage vehicles.
- Turbocharger Failure: The turbocharger can be a weak point, especially on older models or vehicles that have been driven hard.
- Clutch Failure: The clutch can wear out prematurely, especially with aggressive driving.
Performance Tuning
The WRX is a popular platform for performance tuning, with a wide range of aftermarket parts and tuning options available. Some of the most common modifications include:
- ECU Tuning: A custom ECU tune can significantly improve performance by optimizing fuel and ignition timing.
- Exhaust Systems: An aftermarket exhaust system can improve performance and give the WRX a more aggressive sound.
- Intake Systems: A cold air intake can improve airflow to the engine, resulting in a modest performance increase.
- Suspension Upgrades: Coilovers, sway bars, and other suspension upgrades can significantly improve handling and performance on the track.
