how hard of a job is this? i have plenty of time to do it, and my dad has a garage with tools etc, he has decent car knowledge, but he doens't know much about newer engines most of his knowledge pertains to the older cars he works on, im wondering how hard of a job is this i'd really like to save the $ that i'd have to pay a shop to install this, im also wondering if anybody could direct me to a detailed tutorial with pictures (hopefully) of how to do this, information of any kind about this will be greatly valued and i will be very thankful.
