i been thinking about buying a 2000 crv for work but i would like to get a little better milage. i know power would be dropped but if i swapped a b16 into the crv do you think that would up the gas milage any from the 2 liter b20?

 

For some reason i don't think so. I would be inclined to believe that the heavy CRV would need the torque that the b20 makes. I think that the b20 is actually too small for the SUV.
I have been bouncing around the idea of a h2b in mine.

 

I am thinking it would make the b16 work harder thus giving it the same milage as the b20 not working as hard

 

Yes, a b16 has less displacement, but it has VTEC and makes more horsepower than the B20. It would probably use MORE gas.

A non vtec B18 would probably yield slightly better mileage if you really stayed out of the pedal. I'm pretty sure thats the only motor with smaller displacement that LACKS vtec though.

 

if you want good mileage you shouldnt be looking for a suv. even still the crv realy isnt bad on gas if you dont keep you right foot on the floor, i averaged about 225-250 miles on one tank but my wife would get 250-300.

 

Smaller engine will sometimes struggle to keep the car going, so therefore use more gas, even with proper re-gearing. Let's assume all the engine and trans is in perfect order.

The one thing that can get you better MPG would be taller and narrower tires. The tire spec on 2000 CRV is 205/70/15. I would go with 195/75/15 and make sure the tire have good rolling resistance.

The downside would be handling (safety). Depending on how and where you drive, it may or may not be an issue.

 

YES!! And give me the b20z!

But really I dont think so. 3200lbs and not super wind resistant so my guess would be its not worth all the trouble.

vtec or non vtec has nothing to do with it. its the fact that the b16 lacks the torque needed to get the cr-v to get going smoothly.

my family had a 2000 se crv. on regular gas mixed driving. it averaged 25 mpg all year. IMO thats good mileage considering other choices out there.. and the fact that it's automatic.

a b16 civic (manual) will yield you a good 30-35mpg staying out of vtec. but this is factored with what everyone else has stated: weight, gearing, wind resistance.

 

if you could afford it the itr has more tourqe than the b20 it could be a little better but i would think it would matter much if i had it in mine i would just drive faster and get worse mileage

Not to mention that $5,000.00 (cost of swap) buys a lot of fuel

 

I would go with some home made Aero covers, go with a low weight oil (5w20 or even a ow30...but that may destroy the engine) and modify your driving habits.

 

Keep your engine well tuned, buy narrow tires and keep them well inflated, drive miserly, tailgate trucks, lose weight, get a thinner girlfriend, buy a chihuahua...

 

Whats a girlfriend?

Sometimes referred to as a "passenger side airbag".

 

that is a bad idea.....the cost of swaping it would negate the 5 or 6 dollars a week youd save. come on guys man up lets throw a boosted itr motor in it

 

I just did a swap a few months ago on my 97 CRV. B18c1. I love VTEC and if I drive modest, I can still pull 20mpg out of it. Better on highways. VTEC hits pretty hard with the B20 combo, but I'm really happy with it. Its no racer, but it gets respect.

 

did any one think about the fact that he might be reving highing with that small engine to get it up to speed (i.e. using more gas?) plus the extra weigh might be kinda hard on it. idk this is pure speculation. please correct me if im wrong

his whole suggestion rest on the argument that a swap will "increase" his mpg. a stock b20 cr-v can get 25mpg (reg. unlead) easily with mixed driving. if he opted for a vtec setup, that would essentially mean, putting a naturally "high reving" engine into a shell of 3200+ lb car which forces you to rev high to get into the power band, therefore, using more gas.

stick with stock, maybe search for h/i/e setups that do produce hp at the same time helps with mpg.

 

can u say boost or do a h22 swap if u could they have lots of power and r cheaper to swap than a itr swap

 

A drop and belly pan should help the MPG immensely. Rear wing, if you don't have one might help too.

 

The best investment is to mantain proper tire inflation and alignment - beyond that google hyper miling and see if any of those techniques are applicable and safe.

It would be more cost effective to buy light weight enkies and aftermarket 2 piece rotors those remove the worst kind of mass for around town mileage.

And a rear wing is very vague and will likely hurt mileage considerably as the added down force will raise the nose and increase drag.

And remeber that profile when lowering front to rear height should be maintained

Would a belly pan really help with MPG ????? Mythbuster should do a test on that one.

The JDM Civic HX (some years) came with a small plastic panel under the rear of the car (next to the muffler, and flushed to the rear bumper) to improve aero for mileage.

Mugen sells an underbody panel for the Fit that is claimed to help mileage.

SOHC!
do it!

 

that under cover is really nice... Do they sell one for the CR-V...?
