Hi I have a 04 Mazda 3 2.l fwd 5 speed and I'm looking for a way to find a compatability chart of program that can tell me what other engines can be put in place of the original. For the most direct and easyest bolt up possible. This is a maintenance reason. Im on a budget but have already invested to much into the car to throw it away now.Not trying to gain any power or anything flashy just be able to drive to town and back. It's the only car I have other than a Mazda protigue5 that looks like it went thru a meat grinder hahaha but btw has a whappoing 273k miles on it and still runs
