I installed the ASP Racing billet pulley on my coupe and man, that car sprouted wings and flies now. It's hard not to play with it at every light. I put together some install instructions with nice pics to help out anyone that wants to do it themselves. It's in the zip file. The insall should take about an hour and doesn't require a lift or power tools for 6-spd. Automatics require an impact air gun to remove the bolt that holds the pulley in place because there's no easy way to keep the crankshaft from spinning..
