Well I need to put a motor in my Del Sol to get it going for a daily driver. I picked up a Y8 longblock the other day for $200 but the motor was sitting for a while and cylinder walls had some rust which left #2 cyl wall with a pretty pitted rust spot. A friend of mine has a d15b8 block laying around he was going to give me and I was going to do a mini-me on it. After doing the research, I came to figure out that the CR would be ~10.5:1. As I'm not looking for big power out of this motor, the CR isn't appealing to me, and it's even less appealing with the fact that if I do it, i'd have to run 93 oct as well. Well with all that said, my question is this... what kind of gas mileage could I expect from a B8/Y8 mini-me combo? In my coupe I get ~21-25mpg right now.
