ok, ive read through the whole thread and am still wondering two things..
- how much benefit would one get out of mating up an ej207 block with bored ej205 heads over just a full ej205 longblock? and would this be a superior setup to ej257 heads/207 block? 257 combustion chamber is bigger but would avcs not out-weigh that detriment?
- i realize this question is unfortunately relative to locale. but can an ej207 w jdm ecu pass emissions? whats it take to get one to be legal in US if all thats required is smog and ecu scan? i had thought it was a much bigger deal than the comments in this thread seem to indicate, very curious as to the details of what it takes..
