Many thanks to all for helping me clarify my thoughts!  I've spent time trying to gain an education by following threads and many (most?) involve turbo upgrades/conversions.  It starts one to thinking.  It would be nice to have an additional 25-50 HP if I can find it NA, but I recognize I'm not ready to look further at this time.  I can fit the ballparks suggested in the budget and tackle the rest of the carcass first.  Once I've got a good rolling platform, I can begin to play.  First looking for rotor/housing as time allows.  
Ted,      
 
Maybe it was a bad day?  Perhaps perspective.  To clarify, I bought this car new in 1989, I've hung on through moves, divorce, singlehood, remarraige.  I bought it for its engine which fascinated me from the first one I saw in Manhattan in 1972 but never understood until dismantling it last month.  I bought it for its handling, reminicent of my 1959 Triumph TR-3.  I'll NEVER dump it.  I have no idea if that places me into your definition of an enthusiast or not, but it fits mine.   
 
I come from a culture where matching numbers and OEM correctness mean everything.  I've entered a culture where other goals apply.  I'm seeking advice as to potential paths forward from others who have walked them.  I thought that was one of this forum's purposes.  In the end, of course it is I who will decide.  Peace.
