Overview

The 1987 Porsche 911 is a classic rear-engine, two-door sports car from the final years of the “G-Body” (impact-bumper) era, positioned as a premium performance coupe and Targa/Cabriolet for drivers who value mechanical character and timeless styling. For 1987, it benefits from the strong 3.2-liter Carrera drivetrain and a refined chassis that blends everyday usability with weekend back-road capability. It’s ideal for enthusiasts who want an analog driving experience, strong aftermarket support, and long-term collectability. In the classic 911 market, the 1987 model year is often seen as a sweet spot before the major 1989 transmission change and the later 964 redesign.

Key Features

1) 3.2L flat-six power: The 1987 911 Carrera uses Porsche’s 3.2-liter air-cooled horizontally opposed six-cylinder engine (commonly cited around 217 hp in U.S. specification), known for durability when maintained and for its distinctive throttle response and sound. 2) Transmission choices: Most 1987 cars are equipped with the proven 5-speed manual (915) gearbox, offering an engaging, mechanical shift feel; a 4-speed automatic (Sportomatic is not typical here) was available in some markets, but the manual is the most sought-after. 3) Body styles and usability: Available as Coupe, Targa, and Cabriolet, the 1987 911 offers surprising practicality with small rear seats, front trunk storage, and strong visibility compared with newer, thicker-pillared sports cars. 4) Classic 911 handling balance: Rear-engine traction and a communicative steering feel define the experience. With correct tires, alignment, and suspension refresh, it remains a rewarding driver’s car even by modern standards. 5) Strong community and parts support: Because the 3.2 Carrera is widely supported, parts availability, specialist knowledge, and upgrade paths (suspension, brakes, A/C improvements) are excellent for a 1980s sports car.

Common Issues & Reliability

Searching “1987 Porsche 911 reliability” often leads to a simple truth: these cars can be very dependable, but they are sensitive to deferred maintenance and age-related wear. Here are common issues frequently discussed by 1987 Porsche 911 owners and specialists: 1) Valve guide wear and oil consumption: Some 3.2 engines develop valve guide wear that shows up as increased oil use and smoke on overrun, often surfacing anywhere from roughly 60,000–120,000 miles depending on prior care and driving style. A top-end rebuild can be needed if wear is significant. 2) Oil leaks from aging seals: It’s common to see leaks or seepage from valve covers, oil return tubes, crank seals, and thermostat/oil line connections as gaskets and seals age. Small leaks are normal for many classics, but heavy leaks can indicate overdue resealing or improper prior repairs. 3) 915 gearbox wear and shifting complaints: Owners reporting “1987 Porsche 911 problems” often mention balky 1–2 shifts, worn synchros, and tired shift bushings. Symptoms can appear around 80,000–150,000 miles, especially if the car was driven hard or serviced infrequently. 4) Electrical and HVAC aging: Power window switches, alternator/voltage regulator issues, and weak A/C performance are common age-related complaints. Heat is engine-driven and generally strong when everything is sealed correctly, but worn heater hoses and flapper boxes can reduce effectiveness.
