There has been some confusion about how legal engine swapping (in the US) is on some of the forums that I'm on.. so I did the research. I called the EPA and was referred to the following site:
http://www.epa.gov/compliance/resour.../engswitch.pdf
Page 2, second to last paragraph implicitly forbids swapping foreign engines into American cars. Not that I care, I'm going to do it anyway.. but we can put this issue to rest.
FAQ please?
