Welcome to the forum, Lawrence.

For the benefit of those of us who aren't fluent in Hondaspeak, what are the main differences between the dead engine and the replacement that will help fuel economy?

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!!

Gotcha - thanks!

So is the D16Y5the engine from the Civic HX? Aside from the 1st gen Insight, the only other Honda lean burn engine I new about was the d15z1 from the Civic VX.

1996-2000 HX, these are only in the coupe model!!! Same family engine. The better engine to get would have been JDM D15Z1 with the triple Vtec-E for FE, that engine has dual Vtec so you can lean it out even more and have more control if done right! But since i am bot a tuning expert and the HP different between thr two put me off. It also helped that I got a killer deal on the Y5!!
In have already added this to my garage. I am currently sourcing parts and breaking in. Give it about a few weeks, I will post some results!

Thanks for clarifying. Hope you get good results - looking forward to the update.

I don't see your garage entry. ( Your Garage: [ Add new vehicle ] )

So, first 3/4 tank during break in is completed. Engine runs good. Fuel log is done, I am only getting 32.99mpg at this point. Not sure what the problem is just yet. A part of it might be the heavy traffic 4 morning in a roll for about 10 miles each morning. I have also been driving a lot @ 2500rpm and @3000rpm for break in reason, but that's should not affect the mpg too much as that's about a normal traffic speed just around 70mph.

The y5 so far is performing about the same on mpg vs the y7. A lot more power, very smooth! I am going to adjust 1 system at a time and will keep this updated as I go. When I have all the bugs worke out. The Eco mods will begin! Cheers!

Nice car. Use the ecomodder search function in the top left corner. There are some others who have done swaps like this one, looking for the FE that comes from lean burn. Some experienced problems too, IIRC. Reading their threads might be useful for you.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

Good, another HX (sort of) and looks like your a local (I'm in Puyallup).

When you swapped, I assume you used the D16Y5 ECU, wiring harness, and O2 sensor, right? Are you using any sort of instrumentation to verify that it's going into Lean Burn mode?
