Hey I'm doing this too. Purchased the D15Z1. Doing the research on the swap.
Bunch of info out there. Here are some links...

I am sticking with my existing harness and making changes outlined on the first link above. I will just need to get a few connectors.

Do we have an actual idea what the end result mpg will be? Is it 60+? I am hoping that the Z1 engine along with some aero modifications like the aerocivic will get me in the 70's.
