I herd people was getting almost 50 mpg with this setup. I was thinking of swapping a d16y7 into my 89 hatch with automatic tranny, Power steering, and AC, and keep ym exsisting DPFI for the gas milage. Was wondering if anyone on here has done a swap like this and would know of any Problems I would run into or is the y7 a direct swap of my stock d15b2 if anyone wants to know why i was jsut looking to do a good swap for my cruise car. not really looking for a major power gain just something a little better then the d15
