The 1987 Buick Regal Grand National stands as one of the most iconic American muscle cars ever produced. Known for its stealthy black appearance, turbocharged V6 engine, and unmatched performance during its era, it continues to captivate collectors and car enthusiasts. Restoring a 1987 Buick Regal Grand National is both a rewarding and challenging journey, combining mechanical expertise, attention to detail, and passion for preserving automotive history. Whether you’ve just acquired one or are considering a restoration project, this guide provides essential tips to help you bring your Grand National back to its former glory.

Understanding the Legacy of the 1987 Buick Regal Grand National

Before diving into restoration, it’s important to understand what makes the 1987 Buick Regal Grand National so special. Originally released as a performance variant of the Buick Regal, the Grand National earned its legendary status due to its turbocharged 3.8-liter V6 engine that produced 245 horsepower and 355 lb-ft of torque — impressive numbers for its time. It could outpace Corvettes and Camaros, earning the nickname “The Dark Knight” of the 1980s muscle scene. Restoring one isn’t just about rebuilding a car; it’s about reviving a piece of automotive heritage.

Step 1: Evaluating the Condition of Your Vehicle

The first step in restoring a 1987 Buick Regal Grand National is to thoroughly assess its current condition. Start by examining the frame, body panels, and undercarriage for rust or structural damage. The car’s body is prone to corrosion, especially around the wheel wells, floor pans, and trunk area. Next, check the engine and drivetrain components. Many Grand Nationals have been modified or poorly maintained over the years, so understanding what’s original and what’s been altered is key. Document all findings and create a checklist to prioritize restoration tasks.

Step 2: Planning Your Restoration Approach

Restoring a 1987 Buick Regal Grand National can take months or even years, depending on your resources and goals. Decide early on whether you want a full, concours-level restoration that keeps everything original or a restomod that blends classic looks with modern performance. A factory-correct restoration will require sourcing authentic GM or NOS (New Old Stock) parts, which can be expensive but ensures authenticity and collector value. A restomod approach offers more flexibility, allowing for modern upgrades like better suspension, brakes, and electronic fuel management systems while maintaining the car’s signature appearance.

Step 3: Sourcing Authentic Parts

Finding parts for a 1987 Buick Regal Grand National can be one of the most challenging aspects of restoration. Some components are no longer manufactured, so you’ll need to rely on specialty suppliers, salvage yards, or online communities dedicated to Grand Nationals. Key parts like turbochargers, intercoolers, and factory wheels are in high demand. Joining forums such as TurboBuick.com or BuickGN.com can be extremely helpful for locating hard-to-find components and getting advice from experienced restorers. Always verify part numbers and authenticity before purchasing to ensure you’re getting genuine items.

Step 4: Restoring the Engine and Drivetrain

The heart of the 1987 Buick Regal Grand National is its turbocharged 3.8-liter V6 engine paired with a 200-4R automatic transmission. Begin by disassembling and inspecting the engine for wear and damage. Pay special attention to the turbocharger, which may need to be rebuilt or replaced. The fuel injection system should also be cleaned or upgraded to ensure proper performance. Replace all gaskets, seals, and hoses, and consider upgrading to stronger internals if you plan on boosting performance. When restoring the transmission, check for worn clutches, bands, and solenoids — transmission rebuild kits are widely available.

Step 5: Rebuilding the Suspension and Brakes

Handling was never the Grand National’s strongest suit, but restoring and upgrading the suspension can make a huge difference. Replace all bushings, ball joints, and control arms, and consider adding performance shocks and springs to improve ride quality. The stock braking system can also benefit from modern upgrades. New rotors, calipers, and performance brake pads will enhance stopping power while retaining the car’s original look. Keeping the suspension components clean and properly aligned ensures smooth handling and long-term reliability.

Step 6: Restoring the Interior

The interior of the 1987 Buick Regal Grand National was stylish yet simple, featuring gray and black tones with a digital dash display that was ahead of its time. Begin your interior restoration by reupholstering the seats, replacing worn carpeting, and cleaning or refinishing trim pieces. Original dashboard components can be difficult to find, so sourcing replacements from donor cars or restoration suppliers may be necessary. Pay attention to small details like steering wheel badges, instrument cluster lights, and headliner material — these elements can make a major difference in the final presentation.

Step 7: Reviving the Exterior Finish

One of the most recognizable aspects of the 1987 Buick Regal Grand National is its deep, glossy black paint. Achieving a perfect finish requires meticulous preparation. Strip the old paint, repair any rust or dents, and apply a high-quality primer. The black paint should be applied with multiple coats followed by a professional-grade clear coat to achieve a mirror-like shine. Chrome trim, badges, and the distinctive blacked-out grille should also be restored or replaced to complete the authentic appearance.

Step 8: Electrical and Electronic Systems

The 1987 Buick Regal Grand National featured several electronic components, including a digital dashboard and turbo boost indicators. Over time, these systems can fail due to wiring corrosion or component degradation. Carefully inspect all wiring harnesses, fuses, and sensors. Replace brittle or frayed wires and clean all connectors. Upgrading to modern relays or installing new electronic control modules can improve reliability without altering the car’s original character.

Step 9: Final Assembly and Testing

Once all mechanical, electrical, and cosmetic components have been restored, it’s time for reassembly. Take your time during this phase to ensure every bolt, connector, and clip is properly installed. Before starting the engine, double-check fluid levels, torque settings, and sensor connections. Perform an initial startup test to verify that the engine runs smoothly, the turbocharger functions correctly, and all gauges operate as expected. Afterward, conduct a road test to fine-tune performance, handling, and braking.

Step 10: Maintaining Your Restored Grand National

After completing the restoration, maintaining your 1987 Buick Regal Grand National is crucial to preserving its performance and value. Store it in a dry, climate-controlled environment to prevent corrosion and fading. Regularly check oil, coolant, and transmission fluid levels, and avoid prolonged idling. Keep the turbo system clean and lubricated, and drive the vehicle periodically to ensure all components remain in good working condition.

Conclusion

Restoring a 1987 Buick Regal Grand National is not just about reviving a car — it’s about preserving a symbol of American automotive power and innovation. With careful planning, patience, and attention to detail, enthusiasts can bring this legendary machine back to life. From its aggressive styling to its turbocharged performance, the Grand National remains a timeless reminder of when Buick ruled the muscle car world. For classic car enthusiasts, few projects are as rewarding as restoring this legendary icon to its original, menacing glory.
