Looks great - I'm looking to do it. How did you go about parts and how much did it end up costing???

You have 2002, so your upgrade path will be to a 4.6is, not 4.8is. Unless you want to do the facelift at same time which will mean changing all body panels front of A pillar as listed in article here, in which case you can do a 4.8is upgrade.
