West Coast Shipping presents this comprehensive guide to navigating the complexities of acquiring, maintaining, and importing this legendary Japanese performance car across international borders.

Historical Significance & Model Overview

The STI Legacy

The Subaru Impreza WRX STI Version 6 represents the pinnacle of Subaru's second-generation Impreza development. Released in January 2000, the Version 6 (GC8F) was the final evolution of the first-body-style STI before the transition to the "bugeye" third generation. Distinguished by its iconic rally heritage, signature boxer rumble, and formidable all-wheel-drive performance, the Version 6 STI embodied everything enthusiasts loved about Subaru's motorsport-derived technology.

Key Historical Milestones

• Direct descendant of Subaru's World Rally Championship winning cars

• Featured the legendary EJ20 turbocharged boxer engine in its most refined form

• Offered with sophisticated Driver Controlled Center Differential (DCCD) all-wheel-drive system

• Recognized for exceptional all-weather performance capabilities

• Represents the final and most refined iteration of the original body style STI

Model Variations

The Version 6 STI was offered in various specifications, with notable distinctions between trim levels:

Engine & Drivetrain: The Legendary EJ20

2.0L Turbocharged Flat-Four

The heart of the STI Version 6 is its celebrated EJ20 powerplant – a 2.0-liter turbocharged flat-four boxer engine officially producing 280hp at 6,500 rpm and 260 lb-ft of torque at 4,000 rpm (though many believe this was understated due to Japan's "gentleman's agreement" limiting advertised power to 280hp).

Key Engine Specifications

• Displacement: 2.0L (1,994cc)

• Engine configuration: Horizontally-opposed four-cylinder (boxer)

• Block and head material: Aluminum

• Compression ratio: 8.0:1

• Induction system: Single turbocharger with intercooler

• Fuel system: Multi-point electronic fuel injection

• Maximum boost: 14.2 psi (1.0 bar) from factory

• Engine code: EJ207 (Version 6 STI variant)

• Redline: 8,000rpm

Critical Maintenance Points & Common Issues

The EJ20 engine is renowned for its performance potential, but several key areas require vigilant attention:

1. Head Gasket Failures: While less common on STI models than on naturally aspirated Subarus, head gasket issues can still occur. Subaru enthusiast sites recommend upgraded multi-layer steel (MLS) gaskets when replacements are needed.

2. Piston Ring Lands: Under high boost or detonation, the factory pistons can develop cracked ring lands. Symptoms include increased oil consumption and loss of compression. Many owners upgrade to forged pistons when rebuilding.

3. Banjo Bolt Filter: The turbo oil feed line contains a small filter that can clog and starve the turbocharger of oil. According to Subaru specialists, removal or regular cleaning is recommended preventative maintenance.

4. Timing Belt Service: The EJ20 uses a timing belt rather than a chain, requiring replacement every 60,000 miles. Neglected maintenance here can lead to catastrophic engine failure if the belt fails.

5. Turbocharger Health: The factory VF28 turbocharger typically lasts 100,000-120,000 miles before bearing wear or shaft play occurs. Signs of failure include oil smoke, loss of boost pressure, and turbo whistle becoming more pronounced.

Expert Tip: "The EJ20 responds exceptionally well to proper maintenance, but oil changes are absolutely critical. Use only high-quality synthetic oil with proper specifications for turbocharged engines, and change it every 3,000-4,000 miles without exception."

Transmission & Drivetrain Considerations

The STI Version 6 features a robust 6-speed manual transmission routing power to all four wheels through Subaru's sophisticated Driver Controlled Center Differential (DCCD) system.

Common Transmission Issues:

• Shift Fork Wear: Heavy use can cause wear to the shift forks, resulting in difficult shifts, particularly into 3rd gear. Subaru performance specialists note that upgraded shift forks can provide improved durability.

• Clutch Lifespan: Factory clutches typically last 60,000-80,000 miles under normal use. Performance driving or increased power substantially reduces lifespan.

• Center Differential Controller: The electronic DCCD controller can develop issues with age, particularly in the wiring connections and solenoids.

Buyer's Alert: Check for smooth engagement across all gears, particularly third gear when warm. Grinding or notchy shifts indicate expensive transmission work in your future. A complete rebuild typically costs $2,500-3,500 including labor.

Chassis, Suspension & Brakes: Rally-Bred Performance

Handling Characteristics

The STI Version 6 features a sophisticated suspension setup that provides exceptional handling balance with sufficient compliance for daily driving.

Suspension Configuration

• Front: MacPherson strut with aluminum lower control arms

• Rear: Multi-link with aluminum components

• Dampers: Inverted struts (front), gas-pressurized shock absorbers (rear)

• Anti-roll bars: Front and rear

Critical Inspection Points

When evaluating a potential purchase, pay special attention to these suspension components:

1. Control Arm Bushings: Factory rubber bushings deteriorate after 20+ years, causing excessive play and vague handling. As noted in Subaru forums, polyurethane replacements offer improved response and longevity.

2. Rear Trailing Arm Bushings: These are particularly prone to wear, affecting rear wheel alignment and stability. Signs include clunking noises over bumps and uneven tire wear.

3. Shock Absorbers: Original units commonly leak or lose effectiveness. Many enthusiasts upgrade to adjustable coilovers for improved performance and ride height adjustment.

4. Brake System Integrity: The factory 4-pot front/2-pot rear braking system is good but can benefit from upgraded pads and stainless steel brake lines for improved pedal feel and resistance to fade.

5. Alignment Specifications: Ensure the vehicle tracks straight and exhibits no unusual tire wear patterns that would indicate alignment issues or accident damage.

Performance Enhancement: "Many owners upgrade to coilover suspension systems from manufacturers like KW, Öhlins, or Fortune Auto. These provide adjustable damping and ride height, dramatically improving handling while maintaining reasonable comfort for street use."

Bodywork, Corrosion & Interior Quality

Steel Construction with Rally-Inspired Design

The STI Version 6's bodywork is unmistakable with its aggressive stance and iconic rear wing, but several areas require careful inspection after 20+ years.

Critical Inspection Points

1. Rust in Wheel Arches: The rear wheel arches and sill panels are prone to rust, particularly on cars from regions with harsh winters or coastal areas. According to Japanese import specialists, thorough inspection of these areas is essential before purchase.

2. Accident Damage: Given the performance nature of these vehicles, many have experienced accidents or been repaired. Check for even panel gaps, consistent paint finish, and signs of structural repairs.

3. Rear Quarter Panels: These are particularly vulnerable to collision damage and poor-quality repairs. Look for ripples in the metal or inconsistent paint texture.

4. Underbody Protection: Rally-inspired driving often leads to underbody damage. Inspect the floor pans and chassis rails for signs of impact or corrosion.

5. Hood Scoop and Front End: The functional hood scoop can collect debris that may damage the intercooler. Ensure it's clean and properly sealed.

Interior Durability & Electronics

The STI's interior is driver-focused with supportive Recaro seats and rally-inspired touches, though materials can show their age after two decades.

Common Interior Issues

1. Seat Bolster Wear: Driver's seat bolsters typically show significant wear, particularly on the Recaro seats. Quality reupholstery services can restore the original appearance.

2. Center Console Material: The plastic material on the center console tends to become sticky or deteriorate over time, requiring restoration or replacement.

3. Headliner Sag: The headliner adhesive can fail over time, especially in hot climates, causing sagging. Full replacement is the most effective solution.

4. Dashboard Cracks: UV exposure causes dashboard cracking, particularly near the defrost vents. Quality dashboards are increasingly scarce, making preservation of the original essential.

5. Electrical Gremlins: The relatively simple electrical system is generally reliable, but age-related issues with window regulators, central locking, and audio systems are common.

Interior Preservation Tip: "Invest in a quality sun shade and consider applying UV protectant to interior surfaces. Japanese interiors from this era are particularly vulnerable to sun damage, and replacement parts are becoming increasingly difficult to source."
