Barry, you forgot the MX-3 was sold in other countries until '98.
To answer the original question there were no production changes to the B5/B6 for '94-'98. For parts the B5 and B6 DOHC are identical engines except for the rods and cams (B5's have hotter OE cams) there were a lot of parts for the B5 back when, but most have been discontinued several years now.
