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.
