I would like to know if you can swap any civic engine into a 95 accord lx to get over 40 mpg.

Please let me know

 

no...if you want civic MPG's, buy a civic

 

If you swapped a civic motor into an accord you would actually get worse gas mileage than with an accord engine. The accord is a relatively big car so it needs that torquey bigger motor in it to pull it. If you put a little 1.6 liter in that big car you would have to spin the motor up quite high in order to getany kind of power out of it.

 

Even though some of the 1.5 and 1.6 civic engines have relativley the same hp numbers.

 

Question here is; Are the 40+ MPG 1.5 & 1.6L engines the same ones with the relatively same Hp numbers?

F22B1 145hp w/147lb-ft tq @ 4500-5500rpm = 32-36mpg in a 2889lb chassis.

Is the B16B (185hp w/118lb-ft tq @ 7300-7800rpm) getting 32-36MPG in a 2889lb chassis?

I didn't see any 1.5l over 128hp and 106lb-ft tq (D15B VTEC) 128hp /102tq (D15Z7).

The D16B5 would be your best choice under 2.0L. However, you would also need the transmission to go with it, custom axles, custom engine & trans mounts + hoses and wiring. The 0.02¢ that you "might" be saving on fuel would be thrown out the window with the cost of the swap and it's custom parts.

You would probably be better off to spend the money on a larger displacement engine (K24) to get a better MPG. that way you could still have some fun if you wanted to put your foot to the floor.

 

thank you

 

a Honda CVCC would be better.

So does a h22 in an accord give better mpg than the f series?

 

Maybe. It all depends if the engine's got clean injectors, no carbon on the valve's neck, clean TB, air filter, spark plugs, etc. All of those has to be consider when you want the most for MPG.

If you're not into performance then don't even bother with an H22 because it might eat more gas or whatever. Just use the money and do a good tune-up on your F22.

 

Turbo F driven like a grandma will get you close to 40mpg.

 

It would be very hard to get a 95 Accord to get over 40+ mpg. The car is over 15 years old, even when new, most never got close to that. The manual transmission got better gas mileage than the automatic. You mainly see that in Civics/CRXs.

Like Chikin Pickle stated: "If you swapped a civic motor into an accord you would actually get worse gas mileage than with an accord engine. The accord is a relatively big car so it needs that torquey bigger motor in it to pull it. If you put a little 1.6 liter in that big car you would have to spin the motor up quite high in order to get any kind of power out of it. "

The cost/benefit does not appear to be there; to try to swap out or modify the engine to improve gas mileage. Not spending the money on modification will save you money. Maintenance would be cost/beneficial such as new spark plugs, air filter, distributor rotor and cap, pcv valve, etc.

 

Having owned an H22A Accord, no it does not. For starters, the H22A requires premium gas (more money to start with) then using an H22A transmission you are in higher RPM's going at highway speeds. The motor is not a MPG-friendly one - you may get 25mpg tops.

 

^^ x2! Especially when I'm sitting at 4K doing 80mph. HEHE.

 

I have one, had one, and am currently building what will be the third cd H22 series Ive owned. I just never have driven one with a f series and was curious. I figured it was not true but with the statement of smaller engine/bigger car = less mpg I was wondering if bigger engine/smaller car=more mpg. The concept seems like it should make sense.

 

Good concept. But you left out gearing and the H22 and F22 are the same size. The H22 is a wilder engine, more cam, compression and gearing require more fuel. I like your concept. A lightweight Honda with a decent size engine, conservative tune, and tall gears does get close to 40 MPGs. and it still has enough power to accelerate on an on-ramp and pass a slow truck up a hill. Those old CVCC cars are deathtraps nowadays.

 

no cuz you'd have to floor it to overtake a cow

as time goes on we trade mileage for safety, size and luxuries and power

my 2000 accord gets bad mileage, 26, but if i were to crash in it, i'd walk from it to buy another honda,
dual stage airbag plus side airbag and ABS---CVCC doesnt have any of that-you just die lol
its just a motor with a box attatched for the humans to sit in

 

There are a lot more factors that go into it.

H22A is a high compression motor that has larger injectors and more 'performance' oriented gearing in the transmission. Stuffing a V8 into a Civic won't magically net you better gas mileage than the Civic originally had

Practicing hypermiling techniques can get you better gas mileage really with any car, but it is a test of your dedication to continue with them.
