What specific questions do you have? Is this a "stock" Fairmont Turbo?
Actually, quite a number of these were produced, and the 4 cylinder, 2.3L, 140 CI turbo fairmonts were an option from 1980 through 1984 I believe.
The 1980 through 1982's had an engine code of "A", Block Casting of D9EE-BA/D8EE-BA, Head Casting of D9EE-JC/D9ZE/E1ZE, and had "D" chambers and flat bottom intake ports.
In 1984 the SVO Mustang started using the 2.3L turbo engine, with a horsepower rating of 175. In mid 1984 the horsepower rating was increase to 205..
