I am wondering what the fuel economy difference is between the taller 5th gear VX transmission compared to the 5 speed from a DX? I found a Civic with a D15z1 in it, but I'm pretty sure it is still the DX transmission, and wondering how much it is leaving on the table, fuel economy wise.

Is there anything else to consider about a swapped Z1, I'm guessing the ecu has to be from the z1, anything else?

Thanks in advance.
