Tom, the throttle body will bolt right up to your manifold and the rubber boot will fit over the other end, no trouble. What will require a little work is getting the microswitches and the throttle cable to work. I have not done this swap yet but it looks like the shafts for the butterflies can be interchanged and all the original linkage and switch set-up can go onto the new throttle body. Obin did a post about this a while back. You may be able to find it.
I am in the process of replacing the head on the 924 with my spare that was rebuilt before I got it. I am also adding Bursch headers along with the throttle body. I will let you know how much performance all this adds. I'm guessing that there will not be a significant improvement, I'll be happy with anything noticeable......
