So, no results yet, I take it. Hope you'll enter your car in the garage and start a fuel log if you're going to stick around.
D16Y7
SOHC, 16v, 85hp(crank), 34mpg avg,

D16Y5
SOHC, 16v, 115hp(crank), 36mpg avg

The biggest different is that the D16Y5 is a Vtec-E. it only operate 12v below 2800 rpm, it also has a lean burn feature that allows to run very lean A:f ratio on 5th gear between 1900-3000 rpm depending on load. So in simple terms, if you stay off the gas paddle and below 70mph @2900rpm it uses 75% of the 1.6l and inject only 20% of normal fuel amount. Hope this help!!
