For my comparaion I used hmotor prices, and ebay prices. Since that where most people shop.
Also, the only way you can make a true comparison is if you use store prices, because I can have a uncle who works at autozone give me everything free, or get a motor with the homie hook up for $100. You can't compare stuff like that. Plus used prices change based on the seller. One person may sell d16z6 for $250 while another may sell one for $500.
