The Real History of the WRX STI
The Subaru Impreza WRX STI didn't become iconic overnight. It started as a rally homologation special in 1992, built to meet FIA Group A requirements. Subaru needed to sell 2,500 road-legal versions of their WRC car. They did exactly that with the GC8 chassis, and the rest is basically mythology at this point. Here is what actually happened, stripped of the usual car magazine gloss. The original 2.0L EJ20K engine made about 280 horsepower (JDM rating) in the first generation. The turbo spooled relatively early, around 4,000 RPM. The five-speed manual was robust, but the clutch would burn out if you launched it aggressively too many times. I learned that the hard way on a track day in 2004. My clutch started slipping after about twelve hard launches. Replaced it with a Exedy unit, cost about $400 installed. The second generation (2000-2007) is where things got complicated. The GD chassis brought wider track, revised suspension geometry, and the famous 22B-style hood with those enormous air ducts. The EJ207 engine in the JDM models made 280 flat, but the real magic was the driver-controlled center differential (DCCD). This wasn't just a fancy mode selector. You could manually bias front-to-rear torque distribution from fully rear-biased to locked. It changed how the car behaved completely.
I remember testing this on a wet gravel road near my house. Set it to 100% rear bias and the car would step out on acceleration. Dial it to 60/40 and it tracked straight through corners like it was on rails. Most people never figure this out. They just leave it on auto and wonder why the car feels vague in the corners. The third generation (2008-2014) was where Subaru essentially lost the plot. They dropped the five-door body style initially, moved to a longer wheelbase, and the styling became polarizing. The FA20 engine in the later models replaced the EJ series and made more power, but it lost some of the character. The DCT transmission option was a disaster. Sluggish shifts, overheating issues, and it killed the manual preference entirely. The fourth generation brought back the five-door and the manual transmission remained the only option. Power climbed to around 310 horsepower in the US market. The suspension was refined, ride quality improved, and it actually felt competent on road instead of just being a rally car in disguise.
Common problems you should know about. Head gaskets on EJ20 engines are the usual suspect, but they are manageable if you replace them with multi-layer steel gaskets early. Oil consumption in high-mileage examples is real. Check the oil level before you buy anything over 100,000 miles. The CV axles on manual cars tend to fail around 80,000 miles if you drive them hard. Replacement costs around $300 per side with parts alone. The real value proposition here is simple. These cars hold their value unusually well for Japanese performance sedans. A clean early RS model with under 80,000 miles will usually sell for $15,000 to $25,000 depending on condition. JDM imports add complexity but can save you $5,000 or more if you know what you are doing. There is no perfect example to buy. Every one has some issue. The question is whether the cost of fixing it is worth the gain in ownership satisfaction. For most people who actually drive these, the answer is yes. They are not fast in the modern sense. A Civic Type R or a Focus ST will beat them in a straight line. But they handle corners better than almost anything in their price range, and the all-wheel-drive system works in conditions where other cars just spin wheels.

If you want to own one, budget an additional $2,000 to $3,000 for immediate maintenance regardless of what the seller claims. That covers fluids, belts, and likely some worn suspension components. It saves you from surprise expenses down the road and gives you a clean baseline to build from.
