Im going the ASP crank pulley route now. I had the poland pulley, it lasted for about 2 years then the springs started making a noise like they were going to separate so I took it off. I got a LM21 shield and bought a 65mm pulley from Eurocharge in December last year. Well that pulley completely failed earlier this week. The snout of the pulley just split apart and had starting to cut into the front where the EGR piping is in front of the pulley, The scary part is that pulley had less then 2500 miles because I havent been driving my car as much lately.
