I recently blew the engine on my 2.3 but it costs too much to buy the same size engine (about 2gs)... does anyone know if a 2.0 can be swapped in directly? any additional info helps thanks.

2004 mazda 3 Manual Trans

 

still in desperate need of information , if anyone comes across any kind of info please feel free to post here, any links, videos, anything helps. thanks

 

why don't you do a search for replacement ecu's for both engines to see if they are the same.
Try a few different auto sites.

 

Forsure ill b sure to look into that, ive been tryna look up info on all sorts of sites and havent been able to come up with any usefull information.

 

you could call the dealer to compare the ecu's
