AWD 1st gen
I have had my jdm d15b vtec up and running in my AWD wagon chassis for a few weeks. I have a manual vtec switch hooked up. I am running my old d16a6 computer. I am getting about the same mpg as I did before the swap and the power seems a bit less. I am running the d16 throttle body on the d15b manifold. Throwing no codes. I have a p28 that I plan to install when I get the time. I assume I will see more power but should I expect better fuel economy as well? I read that guys are getting 40 mpg in a hatch with a d15b but I am only getting 27 (with my car shifted into AWD for the winter). In 2 wheel drive with the d16a6 I saw as high as 33 mpg but average was more like 30.
