*Edit: The 65mm "Porsche" pulley is the correct part for my car, same exact part number.

Excellent post! Just ordered the tensioner pulleys to replace while I'm in there replacing belts. Pretty substantial savings compared to purchasing each of the tensioner assemblies at $150+ each!

For those who've replaced the tensioner pulleys mentioned, what torque spec did you use for the center bolt? I figure I'd use the same as the idler (deflection) pulley, which is 15nm + 70 degrees turn. Does that sound right?
