some cause a vibration in the crank angle sensor at high RPM. I had an old Perrin that did, they have since redesigned. I've got a Worx Tuning pulley which won an award at SEMA for having a design to elimiate the vibes.. it's easy to do. loosten the belts to the alt and PS and AC pulleys put a long breaker on the crank pulley, put it in 4th and get a buddy to hold the brakes then loosen it up and swap the pulley out. Watch not to lose the key that keeps it from spinning around.

1. Take off belts
2. Put car in fif gear, set emergency brake, have somebody sit in car with foot on brake.
3. Take out 22mm socket with giant breaker bar
4. Grunt, swear, strain, swear some more, and finally loosen crank pulley bolt and remove.
5. Take off old pulley, making sure not to lose the little keyway thingy off the nose of the crank
6. Say "holy shit this thing's heavy!"
7. Put new one on, making sure it seats firmly and that the keyway is properly lined up.
8. Torque crank pulley bolt to proper spec (IIRC its 94ft-lbs)
9. Reinstall belts
10. Start car
11. Enjoy

If you have a 10, 12, 14, and 17mm socket, you're set to pretty much take apart the entire car. Some stuff on the brakes requires an 8mm. You'll need a 22mm for the crank pulley bolt though.

I checked in the service manual, and it is indeed 94ft-lbs for the torque spec. They do also recommend applying a small amount of engine oil to the threads and seat.
