Mitsubishi Conquest

The Mitsubishi Conquest stands as a definitive icon of 1980s automotive design, capturing the essence of the "Radwood" era with its pop-up headlights, boxy silhouette, and turbocharged performance. Originally marketed as the Mitsubishi Starion in most parts of the world, the North American version rebranded as the Conquest—sold under the Dodge, Chrysler, and Plymouth banners—remains a cult classic for enthusiasts who crave analog driving dynamics. As we look back at the landscape of 1980s sports coupes, few cars manage to blend grand touring comfort with raw, boost-heavy excitement quite like this rear-wheel-drive marvel.

Engineering the Legend: The Origins of the Conquest

The development of the Mitsubishi Conquest was a direct response to the rising popularity of Japanese performance cars in the United States. While the domestic market dealt with the aftermath of the fuel crisis, Mitsubishi leaned into advanced engineering to create a platform that could compete with the Porsche 944 and the Mazda RX-7. The secret weapon under the hood was the G54B 2.6-liter turbocharged inline-four engine. This powerplant provided significant low-end torque, making the car feel much quicker than its contemporaries, especially during highway passing maneuvers.

The chassis was designed with a focus on balance and handling. Using a MacPherson strut front suspension and an independent rear setup, the Conquest provided a level of road-holding that was exceptional for the decade. Designers prioritized a wide-body aesthetic in later models, which not only improved stability but also gave the car an aggressive, muscular stance that still commands attention at car shows today.

Performance Specifications and Technical Highlights

Understanding why the Mitsubishi Conquest is still sought after today requires a look at its technical foundation. Unlike many modern vehicles that rely on complex electronic aids, this car offered a pure, visceral experience. The combination of a heavy-duty turbocharger and a well-balanced chassis made it a favorite for aftermarket tuners who recognized the engine’s potential for high-boost modifications.

⚠️ Note: When maintaining the G54B engine, pay close attention to the timing chain and balance shaft assemblies, as these are known wear points for high-mileage examples.

Maintaining Your Classic Sports Car

Ownership of a Mitsubishi Conquest is a labor of love. Because the car utilizes electronic fuel injection (EFI) systems from the 1980s, troubleshooting can occasionally be challenging. However, the mechanical simplicity of the engine bay allows for easy access to components. If you are looking to preserve the longevity of your vehicle, consider the following routine maintenance tips:

• Turbo Cooling: Always allow the engine to idle for a minute before shutting it down to ensure the turbocharger bearings are properly lubricated and cooled.
• Electrical Grounds: Many of the "quirks" associated with these cars are often traced back to poor chassis grounds; cleaning these connection points can resolve many dash and sensor issues.
• Cooling System: The turbo produces significant heat. Replacing the radiator and ensuring the electric fans are functioning correctly is critical for warm-weather operation.
• Vacuum Lines: Replace aging rubber vacuum lines with silicone alternatives to prevent boost leaks that inhibit performance.

💡 Note: Always use high-quality synthetic oil to prevent "turbo coking," which is a common issue when mineral-based oils are subjected to the high temperatures of the turbo unit.

The Evolution of the Conquest Aesthetic

Throughout its production run, the Mitsubishi Conquest saw various styling updates. The most prominent change was the transition to the “Flatty” (flat-body) versus the “Wide-body” designs. The wide-body versions, which featured flared fenders and wider wheels, are generally more desirable to collectors due to their aggressive profile. The interior also evolved, featuring iconic digital instrument clusters in some trim levels that embody the high-tech aesthetic of the 80s.

The interior ergonomics were designed with the driver in mind, featuring heavily bolstered seats that held the driver firmly during cornering. This focus on driver-centric controls helped cement the vehicle's reputation as a legitimate sports car rather than just a stylish commuter. Even today, sitting behind the wheel of a well-preserved model feels like stepping into a time capsule, where the tactile click of buttons and the analog feel of the steering column transport the driver back to a simpler era of motoring.

Finding and Preserving a Hidden Gem

If you are in the market for a Mitsubishi Conquest, the primary challenge is finding one that hasn’t been subjected to excessive modification or rust. Because these cars were often used as project platforms, many have been pushed past their design limits. A clean, stock example is increasingly rare and has seen its value rise significantly in the collector market. When searching for your own, prioritize vehicles with comprehensive service records.

Focusing on the chassis is paramount. Look for signs of corrosion in the rocker panels, wheel wells, and floorboards. While mechanical components can be rebuilt or sourced from the broader Mitsubishi parts bin, structural rust is much harder to repair. Once you secure a solid example, joining a dedicated owner's group or online forum can provide access to a wealth of knowledge that is invaluable for sourcing discontinued trim pieces and performance tips.

As the automotive world moves toward electrification and autonomous driving, the charm of the Mitsubishi Conquest becomes even more apparent. It serves as a reminder of a period when Japanese manufacturers were willing to take risks, resulting in bold designs and engaging performance. Whether you admire it for its sharp, wedge-like lines or for the raw power of its turbocharged engine, this vehicle remains a cornerstone of automotive history. By performing regular maintenance and respecting the unique engineering of the 1980s, owners can ensure that this legend continues to traverse the roads for many years to come, proving that true mechanical character never goes out of style.
