What are the torque specs for the exhaust manifold on a 1990 Eagle Talon?
18 to 22 lbs
yes it will, but the manifold your gonna put the tsi throttle body on must be a turbo manifold as well, well actually not really, it will fit no matter what, its just the non turbo manifold has more vacuum lines runnin to the throttle body, but it should work, never had a non turbo talon but i am very familiar with them, i have a 92 tsi awd talon and a 98 tsi.
It is on the front of the motor to the right of the exhaust manifold I will assume it's in the same place as my 94 Vision. It's kind of behind the motor mount on the left (driver's) side, pretty well hidden. Look about 6-8" directly in front of the left CV joint. I had to locate it from under the car, I couldn't see it from the top.
