The Fiero running gear is just the front wheel drive system out of a GM X-Body car (Citation/Phoenix). If you can get one in good condtion you should be able to transplant most of the running gear from one into the other. The tie rods are even attached to a fixed "steering knuckle" and are used to set the alignment.

The 2.5L Tech-4 is a gutless wonder. I got almost 200K out of one that was installed in my old Buick Somerset - but power was never something it had a surplus of.
