no you dont, all you need is non A/C waterpump pulley from any 1.8-2.0 8v or 16v MK3, and the correct non-A/C belt. You just need to figure out which of the tensioner setups you have, the seperate tensioner type bracket had 2 revisions with different belt lengths. This goes by year:
92-95 = 976mm
96-97 = 1038mm
