Well, in 1989 you had the option for a 2.5L I4 with a non-intercooled turbo running 150HP and 210 ft/lbs of torque or you could get the 2.2L I4 with an intercooled turbo that produced 174HP and 200 ft/lbs of torque.
I have a 1989 LeBaron GTC that could run in the mid 14s stock and mid to low 6s from 0-60. I also found that the GTC ran more around 205HP and 225 ft/lbs of torque to the wheels, but 174/200 is the factory specs, but I have found that Chrysler lies a lot about such numbers, they seem to underrate a lot of cars.
The GTC is the same thing as a Daytona Turbo Z with the Turbo II. If it has the turbo II is is a damn fast car and is nothing to be laughed at.
Check out the
Dodge Garage they have a lot of info about these engines and what not. Also you can check out my two GTC to learn about them as well.
