Replacing the simple pulley with an overrun alternator pulley has been a hot topic among Alfisti in Taiwan. However, I found little, if not none, information of getting a proper OAP for Alfa 156 on forums in Europe. Eventually, it took me two Taiwan trips to get the right one.
I tried upgrading the final gear to improve the torque at low rpm but failed. Details can be found here. I got another used gear box from a scrapped 2004 156 selespeed model. The new final gear ratio now is 3.73 vs 3.56 in the original box. According to Automobile Catalog, the 2 boxes are the same except the final gear. Provided that the 2003 model comes with higher power and more torque with its direct injection engine, Alfa Romeo still put a higher ratio final gear. To me, it seams that it is a reification to a weak spot of the series I 156.

Time flies. It has been 5 years since the last timing belt change. Gauged by the mileage, it is far below the factory recommended life span. However, I wanted to play safe and don’t want to suffer from the consequence of timing belt break down, I just went ahead to change it.
The timing belt on the car still looks good
