Oh sure this has been attempted I would guess a dozen times or so (semi
serious efforts) and discussed perenially on the 20v site.  Can't really
remember the names now.   TAP did a prototype car which is sort of
notorious, it's changed hands four or five times, never did run right.
I think there is a huge laundry list of issues, ranging from adjusting
the compression ratios (the TAP car had a big stack of headgaskets I
seem to recall) to the fact that the main and con rod bearing specs are
different for the boosted cars.  Sorry not to able to be more specific;
I will say that of all the options ever discussed for achieving the S2
goal (import one under various guises; 3B/AAN swap; 10v swap) this is
the one alternative I have never heard of come to fruition, (except the
TAP car)  So try the 20v site, John.
