Back in the olden days there was a turbo'ed 4 cylinder. It was in 1987 and 1988, maybe other years. Were in the thunderbirds, (turbo coupes). I have one with the 5 speed so they are out there. Were replaced with the V-6 supercharged thunderbirds in the 90's, (super coupe).

what years models had these engines ? prefer 5 speed.
I know the 2015 Mustang has them but there out of my price range.
I had a new Turbo Coupe T Bird in 1984. It had a C 4 auto gearbox. The '87 was the highest HP out of the factory, but they were easy to hop up. There was also a German coupe available at the time with the 2.3 turbo. Its name draws a blank this minute.
Model A s had a supercharged 4. When I visited a car show in Austin Texas I saw one for the first time. It had a McCulloch super charger.
A friend in California has one on his Model A. No it isn't factory, but then a lot of things we have weren't.No factory Model A with a supercharger.
