The injectors off a Turbocoupe are 35# and have an inpedance of 2.35 ohms. Therefore they will not work. BUT, the injectors off SUPERCOUPES with the 3.8L V6 supercharged are 36#ers with an impedance of 14.5 ohms and WILL work.
Here's a good website on injectors.

The Mustang computer works with injectors with about 11-18ohms impedance.
Good source for junkyard 24#ers....460 trucks, V10's, Lincoln Mark VIII's with DOHC.
