So I've been thinking lately to get a winter beater (for next year) and since gas is getting more and more costly (especially in the winter) I was thinking of thing to get a better MPG.

I know GM and Chrysler have introduced cylinder deactivation in some of their V8 model..why not do it in a 4 cylinder ? I was looking at a winter beater for next winter and I'm tempted to attempt the following...

Plans :
•kill one cylinder
•do a warm air intake (behind the radiator)
•over inflate the tires to around 35 psi
•Use a 5w20 oil
•NEW• Install some kind of restriction in the exhaust there there would be more recirculated gas in the chambers

Lets look at the specs!

1995 Civic 1.5 litre
102 HP • 32 MPG city, 38 MPG highway =
35 MPG combined

Now lets take one 1 cylinder...
102 HP / 4 x 3 = 76.5 HP,
44 MPG est. combined

Now since its not going to be technicaly a 3 cylinder be cause of the 4th cylinder friction and valvetrain, I would estimate a 70 HP and 42 MPG combined at best...and up to 47 MPG on highway!

The way I was thinking of doing was simply disconnect one fuel injectors and remove the spark plug (to not have compression) and install a filter element in the spark plug hole. Also I'd need to permanently close the intake and exhaust valves of that cylinder.

So far I'm just wondering which cylinder I should deactivate...I know it will inevitabely be a rough ride because of the combustion being not every 90 degrees anymore..but hey, harleys do it no?

Any thought ?

HAHAHAHAhahhah you wouldnt be able to make it up a hill HAHahahahahahah

Killing a cylinder sounds like a good way to junk an engine....
Be smart, use this site: http://forum.ecomodder.com/

if you want a 3 cylinder buy a geo metro...

and do not over inflate tires, it's smarter to buy low rolling resistance tires. The ones that come with the new hybrid cars.

better of with a 93 civic VX hatch.
E-Vetc, = 58mpg highway, and 42 or 44 IIRC mpg city.

sure the VX...there is none around here, this is about building a fuel miser!
I know the vtec-e closes one intake valve to reduce the fuel used..this might be another thing to think about...hehe

dude, buy a cappucino, 3cyl engine,65hp stock(dont remember exactly), that yoyu can turbo.
