There are 2 timing belt kits for the 16v engine ...a 136 tooth belt + manual tensioner or 137 tooth belt + automatic tensioner. A '98 model will almost certainly have come with the manual type & recommendations from lots of previous members (+ on the 306gti6 forum) is to stick with the manual tensioner. The auto tensioner apparently has a higher failure rate.
