17. Pontiac Firebird Trans Am Turbo (1980)
The second generation F-Body Firebird was introduced in 1970 and by late `70s was one of the dominant cars in the segment. Unfortunately, the days of big cube motors and high horsepower ratings were gone so Pontiac decided to invest in new technology to generate power. That new technology was turbocharging and in late 1979 it introduced the Trans Am Turbo.
The engine in question was 301 V8 with Garrett turbocharger bolted on it. Power output was relatively modest at 200 to 210 HP but the torque number was high at 340 lb-ft which resulted in solid performance.
