2000 to 2001.5.

 

Remember, the 2001's had an extra 20 stock hp.

 

If you plan on tuning your B5, I would stay away from the DBW. Who cares about 20 extra HP stock. It's not worth the problems. I've actually heard people buying inexpensive kits to convert their DBW cars to nDBW to avoid limp mode and throttle body closure issues.
