Are you saying the taller transmission is more responsible for the increased MPG than the learn burn engine itself?

If I had the mechanical know how (I am waayyy too limited in that area
) I would do it. Or try. If I were able to do it myself an HX engine swap would be around the same $ as having someone replace my overdue timing belt. I would have to convert my car to manual too.

Makes sense, including it being illegal. Plus the mounts probably being totally different. Still like the idea of installing a same gen HX engine though, if only.
