This 1987 Buick Grand National represents the pinnacle of 1980s American muscle, and this particular example has been meticulously enhanced for even greater performance. Acquired by the seller in 2015, this Grand National has undergone significant upgrades, including a rebuild of its legendary 3.8-liter turbocharged V6 engine. A larger TE-60 turbocharger has been fitted, along with a methanol injection system from Alky Injection, a TA Performance downpipe, and an RJC Performance intake plenum and plate. A 62mm throttle body and a Turbo Tweak chip further optimize the engine’s output. Ceramic-coated exhaust headers and high-flow fuel injectors ensure efficient flow and fueling. The power is now channeled through an Extreme Automatics Stage 1 four-speed automatic transmission to a limited-slip differential. The car is finished in classic black over a black and sand gray cloth interior and features replica 15-inch chrome wheels, a sunroof, and a rear spoiler, staying true to its iconic styling while packing a significantly enhanced punch. Recent maintenance includes the replacement of the headliner, alternator, water pump, and air conditioning compressor, ensuring this Grand National is ready to thrill its next owner.
Rebuilt and Upgraded Turbocharged Power: The heart of this 1987 Buick Grand National is its potent 3.8-liter turbocharged and intercooled V6 engine, which has been professionally rebuilt by RPE Performance Engines. This rebuild was accompanied by a host of performance-enhancing modifications. A TE-60 turbocharger, fitted with a PTP Turbo blanket for heat management, significantly increases airflow. A Duttweiler intercooler neck improves cooling efficiency. The addition of an Alky Injection methanol injection system allows for increased boost and power. A MAF translator and 3-inch MAF sensor ensure accurate air measurement. Exhaust flow is optimized by ceramic-coated exhaust headers and a TA Performance downpipe. The intake system benefits from an RJC Performance intake plenum and plate, along with a throttle body rebuild to a 62mm bore. A Turbo Tweak chip optimizes the engine’s computer for these modifications, while high-flow fuel injectors provide the necessary fuel. Casper engine and fuel injector harnesses ensure reliable electrical connections. This comprehensive list of upgrades transforms the already potent Grand National into a true performance machine.
Enhanced Drivetrain: To handle the increased power output, the Grand National has been fitted with an Extreme Automatics Stage 1 four-speed automatic transmission. This upgraded transmission is designed for increased durability and performance, ensuring smooth and reliable power delivery. The power is then sent to the rear wheels through a factory limited-slip differential, which helps to maximize traction and improve acceleration, a crucial feature for a car with this level of performance.
Classic Grand National Styling: The exterior of this Grand National is finished in the iconic Black (19) paint, which was partially refreshed in 2025 with repainted hood and decklid spoiler. It retains the signature sculpted hood, rear window defogger, sport mirrors, decklid spoiler, and tinted windows that define the Grand National’s menacing yet stylish appearance. The car features a sunroof, adding a touch of open-air enjoyment. It rides on replica aluminum 15-inch wheels with a bright finish and black accents, wrapped in BFGoodrich Radial T/A tires, maintaining the classic Grand National look. Braking is handled by power-assisted front discs and rear drums, providing adequate stopping power for street use.
Comfortable and Functional Interior: The interior features front bucket seats and a rear bench upholstered in a distinctive Black and Sand Gray cloth, with “Turbo 6” embroidery on the front seat headrests, a nod to the car’s legendary engine. The cabin is equipped with air conditioning, cruise control, power accessories, and a Delco AM/FM/cassette stereo with a graphic equalizer, offering a blend of classic features and some modern convenience. A three-spoke leather-wrapped steering wheel is mounted to a tilting column. Instrumentation includes an 85-mph speedometer, a digital tachometer, and gauges for boost pressure and fuel level. A Scanmaster is mounted above the instrument panel for real-time engine data, and an Alky controller is located above the stereo to manage the methanol injection system. Aftermarket gauges for oil pressure and boost are also present in front of the shifter, providing additional monitoring capabilities. Recent interior work in 2024 included replacing the headliner and window beltline seals.
Mileage and Documentation: The five-digit odometer shows 51,000 miles, indicating relatively low mileage for a car of this age, although the accuracy of this reading cannot be guaranteed. The car is offered with service records, providing documentation of the work performed, including the engine rebuild and upgrades. The Carfax report shows no accidents or damage, offering further peace of mind to potential buyers.
