  1. Mazda 6 1st Generation (2002-2008)
    Hi, I've been looking around and I cannot seem to find anything on this... It just crossed my mind. Similar to alot of Honda or Mitsubishi motors Would the 2.3l mzr top end from the Mazdaspeed motors bolt onto the 2009-2012 Mazda 6/ Ford fusions 2.5l duratech... I've seen people do 2.5l duratech...
