1987 Buick Regal Turbo: The Last Great Rear-Drive Buick Muscle Coupe

The 1987 Buick Regal Turbo occupies a peculiar and fascinating place in American performance history. It was not a pony car, not a Corvette rival in the traditional sports-car sense, and not an old-school big-block relic. It was a formal-roof, body-on-frame, rear-drive Buick coupe with a turbocharged V6, an overdrive automatic, and the manners of a late General Motors G-body. Yet in its best-known forms, especially the Grand National and GNX, it became one of the most formidable American production cars of its period.

For clarity, the collectible 1987 turbocharged Regal family is centered on the LC2-powered Grand National, Turbo T, WE4 Turbo T, Limited Turbo, and GNX. The prompt-friendly shorthand often combines Buick Regal, Regal T-Type, Regal GS, and Regal Limited Turbo, but Buick’s historically significant 1987 performance cars were not defined by a single GS turbo model. The relevant mechanical story is the intercooled 3.8-liter LC2 turbo V6 installed in specific Regal packages during the final year of the rear-drive second-generation Regal.

Historical Context: Buick’s G-Body Rebellion

Corporate Background: Performance Without a V8

By 1987, Detroit performance had reassembled itself under stricter emissions rules, higher fuel-economy pressure, and a market increasingly interested in fuel injection rather than cubic inches. Buick’s answer was unusually sophisticated for an American intermediate coupe: a turbocharged, sequentially fuel-injected 3.8-liter V6. The engine family had roots in Buick’s long-running 231 cu in V6, but the LC2 specification used in the later turbo Regals was far removed from the workaday naturally aspirated versions found in ordinary GM products.

The second-generation Regal had arrived for 1978 on GM’s downsized A/G-body architecture and was restyled for 1981 with cleaner aero-era surfacing. It retained the ingredients enthusiasts still value: a separate frame, front engine, rear-wheel drive, a live rear axle, and enough engine bay space to package forced induction without turning the car into a service nightmare. At the same time, GM was preparing a broad shift toward front-wheel-drive intermediates. The 1987 Regal Turbo therefore became a last-of-line car in more than one sense: the last rear-drive Regal coupe of its generation and the final, most mature expression of Buick’s turbo V6 program.

Design and Motorsport Influence

The Regal’s formal roofline and upright proportions were not exotic, but they mattered. The Regal body had strong NASCAR associations in the early 1980s, when Buick enjoyed major stock-car visibility and the Grand National name drew directly from that competition vocabulary. The production Grand National was never a homologation special in the European sense, but it successfully converted racing credibility into showroom identity.

Visually, Buick’s genius was restraint. A 1987 Grand National in black with blacked-out trim looked menacing without resorting to scoops and stripes. A Turbo T or Limited Turbo could be far subtler still, wearing chrome, conventional colors, padded luxury interiors, or even a column shifter. That split personality is central to the car’s collector appeal: Buick sold both the villain and the sleeper.

Competitor Landscape

The LC2 Regal arrived in a market crowded with renewed domestic performance. Ford’s Mustang GT 5.0 had become the street-racing benchmark. Chevrolet’s Camaro IROC-Z and Pontiac Firebird Trans Am offered Tuned Port Injection V8s and sharper chassis tuning. The Corvette sat above them as the dedicated two-seat performance flagship. Buick approached the same conversation from the side door: torque, boost, traction, and anonymity.

In raw acceleration, the Turbo Regal embarrassed many cars that looked more overtly sporting. Its 355 lb-ft factory torque rating was the key number. Where naturally aspirated V8 rivals needed rpm and gearing, the Buick leaned on boost and a broad midrange. The result was not a high-strung road-course car, but a brutally effective stoplight and quarter-mile machine.

Engine and Technical Specifications: Buick LC2 Turbo V6

The 1987 LC2 was rated at 245 hp and 355 lb-ft in standard Turbo Regal applications, including the Grand National, Turbo T, and Limited Turbo. The GNX, completed by ASC/McLaren for Buick, received additional hardware and calibration changes and carried an official 276 hp rating. Period testing and later dyno experience have long suggested Buick’s factory numbers were conservative, but the factory ratings remain the only proper baseline.

Driving Experience and Handling Dynamics

Throttle Response and Boost Character

A stock 1987 Turbo Regal does not behave like a naturally aspirated small-block car. Off boost, it is docile, almost ordinary. The accelerator initially brings the familiar softness of a large American automatic coupe. Then the turbocharger begins to work, the boost gauge climbs, and the car surges forward with a density of torque that still feels modern in concept if not in refinement. The engine is not musical in the European sense; it is industrial, slightly muffled, and purposeful. The reward is not revs, but acceleration delivered in a thick wave.

The 200-4R automatic is central to the experience. Properly adjusted, it gives the car a relaxed highway gait through overdrive and decisive part-throttle response around town. It is not a manual-transmission driver’s car, and Buick never pretended otherwise. The gearbox suits the LC2’s character because it keeps the engine in the boost-rich middle of the tachometer rather than asking it to chase rpm.

Steering, Suspension, and Road Feel

The Regal’s chassis is pure GM G-body: independent front suspension with coil springs, a live rear axle on coil springs, and recirculating-ball steering. The performance models gained firmer tuning than a standard Regal, but the car remains a product of its architecture. The front end is not razor-sharp, the steering does not chatter with feedback, and the body can feel deliberate in quick transitions.

That said, the Buick’s dynamic priorities make sense. It was built to put torque down, cruise at speed, and dominate straight-line contests. With decent tires and a sound suspension, it has honest balance for a body-on-frame coupe, but its limits arrive with the vocabulary of understeer, axle movement, and brake management rather than delicate adjustability. The GNX improved rear-axle behavior with a special rear suspension arrangement designed to reduce wind-up and plant the tires more effectively under boost.

Braking and Real-World Use

Turbo Regals used front disc and rear drum brakes with the electrically assisted Powermaster brake system. When healthy, the system is adequate for street use. When neglected, it becomes one of the model’s best-known ownership concerns. The car’s performance can outrun its brakes on repeated hard use, a reminder that the Regal Turbo was engineered as a devastating road and drag-strip weapon, not a track-day endurance tool.

1987 Buick Regal Turbo Variant Breakdown

The 1987 model year is especially rich because Buick offered the LC2 in more than just the black Grand National. Production numbers below are the widely cited 1987 turbo-Regal figures used by Buick Turbo Regal historians and marque specialists. Regular naturally aspirated Regal and Regal Limited production is not equivalent to the turbo production ledger and is not treated here as part of the LC2 performance count.

Ownership Notes: Maintenance, Parts, and Restoration

Maintenance Priorities

The LC2 is durable when kept close to factory tune and supplied with clean oil, good fuel, correct sensors, and a healthy cooling and fuel system. It is also intolerant of detonation. A tired fuel pump, weak ignition, vacuum leaks, poor grounds, or incorrect boost control can turn an otherwise strong engine into an expensive lesson. The car rewards methodical diagnosis rather than parts-swapping bravado.

• Engine oil: Conservative owners commonly use short oil-change intervals, especially on turbocharged cars that see boost regularly.
• Transmission: The 200-4R depends heavily on correct throttle-valve cable adjustment. Incorrect setup can damage the transmission quickly.
• Fuel system: Fuel pressure, injector condition, pump health, and the factory-style fuel-pressure regulator setup are critical to safe boost operation.
• Cooling system: Radiator condition, fan operation, hoses, thermostat, and intercooler plumbing should be treated as baseline inspection items.
• Brakes: The Powermaster unit should be tested carefully. Accumulator, pressure switch, motor, and fluid condition matter.

Known Problem Areas

Common Turbo Regal issues are well documented. The driver-side exhaust header is known to crack. Vacuum lines age and create drivability faults. Mass-airflow sensors, ignition modules, coil packs, and crank sensors can cause intermittent running issues. Rear main seal leaks are not unusual on Buick V6s. Body rust should be inspected at the lower doors, floors, trunk, rear wheel openings, frame areas, and around T-top openings where applicable.

On cars with modifications, documentation is everything. Larger injectors, aftermarket chips, adjustable wastegates, hot-wired fuel pumps, upgraded turbos, and scan-tool tuning are common in the Turbo Buick world. Some are sensible period-style improvements; others are evidence of a hard life. A collector-grade car should retain its original drivability, emissions hardware where required, correct badging, and matching option-code documentation.

Parts Availability and Restoration Difficulty

Mechanical parts support is strong by 1980s performance-car standards. The G-body platform has a large restoration and performance aftermarket, and the Turbo Buick community has preserved deep technical knowledge. Trim is more complicated. Grand National-specific exterior pieces, correct wheels, interior fabrics, and unmodified engine-bay details can be costly. GNX-specific components are in a different category entirely; numbered-car provenance and correct parts can dominate the value conversation.

Cultural Relevance, Racing Legacy, and Collector Desirability

The 1987 Buick Regal Turbo succeeded because it violated expectations. It wore a Buick badge at a time when many enthusiasts associated Buick with comfort, not intimidation. It used a V6 when the street still worshipped V8 displacement. It shifted itself when manual gearboxes carried enthusiast status. And yet, on the road and drag strip, it delivered results that forced respect.

The Grand National became an instant symbol of blacked-out American menace, and the GNX amplified that image into legend. The cars have appeared throughout enthusiast media, drag-racing culture, video games, and film, with the black Grand National shape becoming shorthand for boosted American street performance. More importantly, the Turbo Regal community kept the cars alive technically. Few 1980s domestic performance cars have such a mature knowledge base for tuning, preservation, and documentation.

Collector desirability follows a clear hierarchy. The GNX sits at the top, with public auction results for exceptional low-mile cars reaching well into six-figure territory and the best examples exceeding $200,000. Standard Grand Nationals are the most liquid and recognizable. WE4 Turbo T and Limited Turbo cars appeal strongly to marque specialists because of their lower production and sleeper character. Condition, originality, documentation, mileage, rust history, and modification quality are the determining variables.

FAQs: 1987 Buick Regal Turbo, T-Type, Limited Turbo, and GNX

Is the 1987 Buick Regal Grand National reliable?

Yes, if maintained correctly and kept free of detonation. The LC2 V6 is fundamentally strong, but it depends on proper fuel delivery, ignition health, boost control, sensor function, and cooling. Neglected or poorly modified cars can be troublesome.

What engine is in the 1987 Buick Regal Turbo?

The key engine is Buick’s LC2 3.8-liter, 231 cu in, turbocharged and intercooled OHV V6. In standard 1987 Turbo Regal form it was rated at 245 hp and 355 lb-ft. The GNX version was factory rated at 276 hp and 360 lb-ft.

What is the difference between a Grand National and a Turbo T?

The Grand National was the blacked-out, image-defining package. The Turbo T used the same basic LC2 powertrain but could be ordered in other colors and in a more understated specification. The WE4 Turbo T was a special black Turbo T variant produced in much smaller numbers than the Grand National.

How rare is the 1987 Buick Regal Limited Turbo?

Widely cited production records list 1,035 1987 Regal Limited Turbo cars. They are prized because they combine the LC2 turbo engine with the more formal and luxury-oriented Limited trim.

What are the most common problems on a 1987 Turbo Regal?

Common issues include Powermaster brake faults, cracked exhaust headers, vacuum leaks, aging MAF sensors, ignition-module or coil-pack failures, fuel-pump weakness, rear main seal leaks, 200-4R transmission wear from incorrect TV-cable adjustment, and body rust.

Is the GNX really faster than the Grand National?

Yes. The GNX received ASC/McLaren-developed upgrades including revised turbo hardware, intercooling and calibration changes, special instrumentation, and rear-suspension improvements. Period testing recorded significantly quicker acceleration than a standard Grand National.

Did Buick make a 1987 Regal GS Turbo?

The historically documented 1987 LC2 turbo performance cars are the Grand National, GNX, Turbo T, WE4 Turbo T, and Limited Turbo. Buyers should verify option codes, engine code, VIN details, and factory documentation rather than relying on informal GS terminology.

Are modified Turbo Regals worth less?

Not always, but collector-grade value generally favors originality, documentation, and reversible changes. Period-correct, expertly tuned upgrades can be appealing to drivers, while undocumented high-boost builds, missing factory parts, or poor wiring typically reduce desirability.

What makes the 1987 model year special?

It was the final year for the rear-drive G-body Regal and the most developed year for the intercooled LC2 turbo cars. It also brought the GNX, the ultimate factory-sanctioned expression of the Turbo Regal concept.
