i was curious about swapping a d series engine into a 90 integra so it would get higher mpg. i know i am gonna get flamed on for this but i really love the second gen integra and i also love the idea of the civic vx getting like 50 mpg. i know that it will need to be wired for vtec and the five wire o2 sensor but has anybody got any more info on this. any POSITIVE input on this would be greatly appreciated.
thank you jake
