yea, the old prelude si's had "b" 20's, which are said to be an early h-series, it was a real oddball (nothing like the other b16/b18/b20's)
I believe that these tranies should work, as a complete list (as in any tranny mated this these engine codes)
f22b1
f22b2
f22's from odyssey (b6?)
h23
f23*
note the h23 will need the flex plate mentioned earlier (i believe).
the engine code h22 should be avoided for reasons of different gearing (pretty sure it has shorter gears, the engine revs higher)
