You don't need a smaller motor to accomplish your goal. You need a better way to use the fuel. Like fuel cutoff, fuel heaters and engine management.

I've got fuel cut off like all the newer hondas and stuff, so that's there. I have engine management also. Fuel heaters don't work according to diamond larry which makes sense to me but meh.

I think the 1.2 versus 1.5 would be a huge difference in mileage.

I agree. You should sleeve your engine and use smaller pistons. That would be sick. A 4 cylinder 1.0L engine. :)

Sleeving (at least in its normal sense) does not affect displacement. The sleeves are the gaps outside of the piston.

The sleeves would be the junk with the holes which replace the just empty area:

I been doing some reading on fuel heaters and I think my problem may be that I'm running too hot. I'm running straight out of the lower radiator hose and with my 195 thermostat it's probably too much. I've heard that there is a relatively narrow window of temperature that is most effective; like 140-160 or so. I heard from too many people that they do work so it about has to be my setup.

See I told you fuel heaters work, it just needs to be adjusted. Megasquirt would at least improve fuel economy by 2mpg. But spending a crap load just to get 2mpg is pointless.

I can do everything megasquirt can do with my stock ecu for free, plus a lot more megasquirt can't do, plus with more support, plus with just all around awesomeness.

Soon I will have awesomeness too! Hopefully with support!

Actually that's incorrect, SVO. What you are referring to is a block guard [as demonstrated in the first picture]. This essentially makes the engine a 'closed deck' design. Aftermarket sleeves appear to be fitted to the engine in the lower picture. Sleeving an engine is basically replacing the cylinder walls with stronger walls, and while doing this, you can either put in larger or smaller diameter bores. I actually had a covnersation with Earl Laskey and Dan Benson about sleeving my 1.5L down to a 1.3L or smaller. They discouraged me from doing so, as the sleeves would have to be custom. They make their sleeve blanks at a diameter larger than the diameter I would need to get below a 1.4L engine. Not to mention, custom pistons would need to be made, which would be $$$.

Haha, it reminds me of that cheezy 80's movie, 'The Wraith'

I suck. I think I was confused by the DIY sleeving article that's on honda-tech. Seems more like a DIY block guard I guess, :(
