1989 Pontiac 20th Anniversary Turbo Firebird Trans Am

For the fourth of July, here’s some eighties American iron.

“The Only Modification It Needed To Pace The Indy 500 Was A Decal.”

For 1989, there was big news in the Pontiac camp with the release of the 20th Anniversary Turbo Firebird Trans Am, which was essentially a Trans AM GTA coupe with a special engine option and some specific trim elements.

Rated at 250 bhp but actually making about 300 bhp, the LC2 3.8 liter sequential fuel injected turbocharged and intercooled V6 was teamed with the 200-4R four speed automatic transmission. Mileage was 16 city/24 highway by the standards of the day (15/22 by today’s standards) and nobody cared. What they did care about was the acceleration—Car & Driver managed to achieve a 4.6 second 0-60 time (Pontiac had claimed 5.5 seconds) and a top speed of 153 mph. At least in power, the third generation Trans Am had come a long way from 1982

For $31,198 (about $59,900 in 2014 dollars) 20th Anniversary Turbo Firebird Trans Am buyers got all the Trans Am GTA exterior and mechanical equipment which included four wheel disc brakes, fog lamps, special performance suspension, a rear limited slip axle, and 245/50-VR16 tires mounted on gold 16 x 8 diamond-spoke aluminum wheels. Turbo Trans Am-specific additions included larger brake rotors and softer front springs. The only color available was white with Turbo Trans Am emblems on the fenders and 20th emblems on the nose and rear pillars.

Inside, standard GTA equipment included power door locks, power windows, power mirrors, power antenna, tilt steering wheel, cruise control, rear window defroster, and remote deck release. Turbo Trans Am owners also got a turbo-boost gauge inside the tachometer face.

Pontiac built a total of 1,550 Turbo Trans Ams for sale (there were another 5 test cars), with 85% of them being t-tops with a leather interior (buyers could order a cloth interior and/or the hardtop, but few did).

Unlike many other eighties cars, Turbo Trans Ams hold their value just fine. According to Hagerty’s valuation tools, all the money for a 1989 20th Anniversary Turbo Trans Am in #1 condition is an astounding $47,700. A more “normal” #3 condition example is valued at $20,700. Turbo Trans Ams often come up for sale in the Hemmings Motor News classifieds. As I write this in July 2014, there’s one with 835 miles advertised for $31,500.
