1999 Mitsubishi Eclipse GSX: The Ultimate Guide to the Turbocharged Legend

When it comes to iconic 90s tuner cars, the 1999 Mitsubishi Eclipse GSX stands tall as a symbol of performance, style, and rally-bred engineering. Known for its turbocharged power, all-wheel-drive grip, and aggressive styling, the GSX remains a sought-after gem among enthusiasts. In this SEO-optimized guide, we dive deep into what makes this car a legend, its specs, buying tips, and why it’s still turning heads decades later.

History of the Mitsubishi Eclipse GSX

The Mitsubishi Eclipse debuted in 1990 as part of the Diamond-Star Motors (DSM) partnership between Mitsubishi and Chrysler. By 1999, the second-generation Eclipse had evolved into a performance icon, with the GSX trim representing the pinnacle of its lineup. As the final model year for the turbocharged GSX, the 1999 edition marked the end of an era before Mitsubishi shifted focus to front-wheel-drive configurations.

Key selling points included its rally-inspired mechanics and accessibility to tuners, cementing its place in pop culture (thanks to films like The Fast and the Furious).

Design: Aggressive Style Meets Function

Exterior:

The 1999 Eclipse GSX featured a bold, wedge-shaped design with pop-up headlights (a hallmark of second-gen models), a raked rear spoiler, and flared wheel arches. Its compact coupe body exuded sportiness while maintaining aerodynamic efficiency.

Interior:

Inside, the GSX offered a driver-focused cockpit with bolstered bucket seats, a leather-wrapped steering wheel, and analog gauges. While not luxurious by modern standards, its no-nonsense layout prioritized functionality—perfect for spirited driving.

Performance: Turbocharged Thrills

Under the hood, the 1999 GSX packed a 2.0L 4G63T turbocharged engine, renowned for its durability and tuning potential. Key specs:

• Horsepower: 210 hp @ 6,000 RPM
• Torque: 214 lb-ft @ 3,000 RPM
• Drivetrain: All-wheel drive (AWD)
• Transmission: 5-speed manual or 4-speed automatic

The AWD system provided exceptional traction, launching the GSX from 0-60 mph in 5.8 seconds—a blistering pace for its era. Paired with a robust aftermarket scene, the 4G63T engine could easily surpass 300+ hp with basic upgrades.

Driving Experience: Raw and Engaging

Behind the wheel, the GSX delivered a visceral experience. The turbo’s rush of power, precise steering, and balanced chassis made it a favorite on twisty roads and drag strips alike. Compared to rivals like the Honda Civic Si or Acura Integra Type R, the GSX stood out with its AWD stability and turbocharged torque.

Buying a Used 1999 Mitsubishi Eclipse GSX: What to Know

If you’re hunting for a GSX, keep these tips in mind:

1. Mileage & Maintenance: High-mileage examples (100k+ miles) are common. Look for service records confirming timing belt changes, oil maintenance, and turbo care.
2. Rust Check: Inspect wheel wells, undercarriage, and strut towers for corrosion.
3. Modifications: Many GSXs have been modified. Stock examples are rare and pricier, but heavily tuned cars may have hidden issues.
4. Engine Health: Listen for knocking sounds (signs of crankwalk, though less common in 1999 models) and check for turbo shaft play.

Expect to pay 10,000–20,000 for clean, low-mileage models, with pristine units fetching higher premiums.

Modifications & Tuning Potential

The 4G63T engine is a tuner’s dream. Popular upgrades include:

• Boost Controllers: Safely increase turbo pressure.
• Exhaust Systems: Reduce backpressure for horsepower gains.
• ECU Tuning: Unlock hidden power with aftermarket chips.
• Bigger Turbos: Garrett T28 or FP Red hybrids for 400+ hp builds.

AWD drivetrains handle added power effortlessly, making the GSX a drag strip or track-day beast.

Legacy & Collectibility

The 1999 Eclipse GSX’s discontinuation after this model year has boosted its cult status. Today, it’s celebrated as a bridge between raw 90s performance and modern tuning culture. Well-preserved examples are rising in value, appealing to collectors and enthusiasts seeking a slice of automotive history.
