Don't think so, bro-


I am certain that it could be done. That being said, it may be difficult and you would have to change from a flex plate to a standard flywheel on the output shaft.


Keep in mind that the Isuzu 5 speed used in the 4 cylinder Fiero is not the same as the Getrag 5 speeds used in 1986 1/2 and later Fiero GT V6. The Isuzu will fit the V6 but the Getrag is stronger. Expect a multitude of problems converting automatic to manual. Fieros are selling so cheap that I would recommend buying one already set up the way you want.
