Help!! Engine replacement 2004 with 2007 2.3l possible?
 

I am in dire help and have a quick question. I have a 2004 Mazda 3s 2.3 and found a 2007 2.3L for 900. Can this be a direct swap?

Thanks for any help. My current motor spun s bearing :-\ and in need of a new motor bad.

Anyone? Is it a direct swap or do I need anything else? I know its the same 2.3 engine.

I'm not really sure but would think if you used the harness and all sensors for the 2004 then it should be okay.
