I have a 2000 civic with the D16Y7 engine installed. i am wanting to use this car as my DD and am looking for something with a little more power, and possibly increase gas mileage, seeing as i only get 30mpg's on average. What would be the most viable swap? I was thinking of swapping over a Y5 or Y8 head, what kind of gas mileage results would i turn up? and what would be needed to complete this swap? btw, its a MTX
