Does anyone know the difference between SEFI and MPFI? I was trying to compare the mazda6 MZR engine and fusion Duratec engine and the only difference I can see is the MPFI (really can't find any specs on the two:banghead: ). Iím sure there are other differences but Iím at the point were I might try to swap parts (aftermarket) to see if any of it will work.
