I'll second the comment about not switching to synthetic after running regular oil for a large number of miles. My last car (a 2000 V8 Firebird) I purchased with 25k miles on it. It had always had regular oil up to that point. I changed to Mobil 1, and my oil pan gasket began leaking. The synthetic can leak through even tiny gaps that regular oil wouldn't go through.
As far as anything detrimental to the engine itself though, there's nothing negative that can happen to an engine by switching to synthetic, at any mileage. As long as you don't mind possibly replacing a gasket or two, you won't have any problems.
