My 2005 6i sport (2.3L automatic) engine is toast and I am going to replace it. This engine is by far the most gustless POS I have ever had. That being said I can't justify the money to put it in my Mazda again. Has anyone swapped to the Mazdaspeed motor with manual trans conversion, or the V6 with manual trans. I am thinking that the V6 would be easier since the Mazdaspeed is all wheel drive. Please help me with this problem. Dont tell me to just sell mine and buy a V6 or Mazdaspeed, because that is not an option for me at this time. I have to keep this $#!tty car for at least 2 more years. Thanks In advance for any knowledge that helps.
