Thanks for all the feedback. 
I'll start making some contact with people thta you recommended.  From what I have seen at Regionals, there's lots of 240z, a few 944s and stuff like that running ITS.  I know the GTV6 is listed as ITS.  I intend to prepare it as a fun, safe track day car, and it seems to make some sense to prepare it to a popular SCCA class rules so that it is more saleable when the time comes.
BTW Quickshoe, I sold all my worthwhile Crossle spares with the car.  I do have a number of old lucas starters and a flywheel or two sitting around...they are good for holding things down on windy days.
Again, thanks for the replies.  
Dan.
