I have yet to install mine, but I will take it to my mechanic along with the header this Thursday... reason being that the belt tensioner takes a lot of force to relieve the belt from the alternator and also you may need an impact wrench to remove the stock pulley...
You definetely want to take it to a shop. You can do it yourself, but if you want things to be easier on yourself you may want to have them do it because they have an impact gun to pull the old pulley out. I just had it installed on my car and if I did it myself without an impact gun I'd be having a hard time doing it myself.
Thank you.: Props to Zen Motorsports for an outstanding job on the Turbo fabrication, and Props to Hass Autoworks for hooking me up with so many sweet parts, You guys Rock!
