Can I replace engine on 2006 mazda 3 , 2.3l , std emissions, manual trans with engine from 2008 Mazda 3? Thanks for any help, Bill

 

Ahhh, now that makes a bit more sense. As for advice on this particular swap, while I believe it is a relatively easy swap, there are those on this board with more specific knowledge on this subject than I have. Sorry I couldn't be of more help.
