Go on any of the grand prix forums. I just did my 02 SSEi. Think I have pics on here? ZZPperformance.com or intenseracing.com have many after market mods. DO NOT DO ANY ENGINE MODS WITHOUT SCANNING FOR KR. !!!!! You cant just put on a smaller SC pulley and go. Please be informed. These engines can go boom if your careless. If you want to know more leave me know. Im sure there are other guys out there that can help as well.
