Nice ride! Check out
www.svoca.com,
www.turboford.net and
www.stangnet.com to learn all you ever wanted to know about the 2.3 turbo! Once you get it running, you're gonna blow away at the power it has!
First things I would do is tear down the top half of the motor, clean it up, fix all the ghetto wiring, replace all vacuum hoses, give it a complete tune-up with Motorcraft parts ONLY (believe me when I say Motorcraft ONLY!) and get yourself a Gillis boost valve.

Once you get it running right and see the kind of power it has, that will motivate you to finish everything else! Good luck!
