So I just swapped in a JDM GSR in my teg. Motor runs strong but sort of hate the gas mileage im getting. Trying to see if its normal. On a full tank im getting about 300-320 miles on 91 octane. Mostley highway driving. Heavy foot every now an then but nothing to crazy.

 

Maybe its due for a tune up. They maybe low mileage, but i would still do a tune up.

 

300-320 miles and the tank is what 10 gallons. 30-32mpg, not bad.
What did you expect?
Is the car tuned at all? What ECU JDM or USDM?
Did you put in new plugs and plug wires after the swap.

 

JDM ECU's are tuned differently, I believe the engines get slightly less gas mileage than USDM ones do.

 

If I got 32mpg, I'd crap a brick.

2000 GSR, engine completely stock. I do anywhere from 190 to 220 miles a tank.

And I drive like a pseudo-hypermiler around town. Light throttle, shift at 3,000 rpm, as much coast time as conditions allow, etc...

Mileage is affected by how the car is driven, but also by the environment it is driven in. I have a 30 to 45 minute 6.6 mile, pure surface street commute (that's an average speed of 8.8 to 13.2 mph, depending on the traffic). Nothing gets good mileage idling at red lights.

Honestly, for mostly highway driving, 32mpg is better than the EPA rated the (US version of the) car for (22/28 is the GSR rating). And most people complain because they never get as good of mileage as the car was rated for...

 

You have a point. I didnt consider how small the gas tank was. I think the tank is more like 11 gallons though. I replaced everything..

Timming belt
cap rotor
plugs, wires
JDM ECU

 

that's excellent mileage. i have a jdm itr on the jdm ecu and get 280-300 miles per tank on average

 

What transmission are you running?

 

im assuming this is in a 91-93 integra body?

 

Sounds like normal gas mileage to me....you must be coming from a domestic that gets 18mpg w/ a 40 gallon tank.

 

^^
Lol. Damn that's some nice gas mileage. I'd be happy with 300-320 anyday.

I have a freakin' fuel economy car and I get 250-280 (depends on where I drive) a tank only.

Naw DC 94 LS. Need to update my avatar

 

180 horse power and around 30 mpg. Damn that is very very good.

 

refill your tank to the top. set your trip meter to 0, drive until you feel its time to refill again. Refill and look at how many gallons you refilled. take the number of miles you drove from the trip meter and divide it by the # of gallons refilled. should give you the most accurate mpg

 

thats pretty good mileage i wouldnt complain. keep up with maintence and you'll be able to keep that mpg up.

 

That is horrible gas mileage. **** if I got that kind of gas mileaage out of a gsr I would swap in a ls asap.

 

seems to be about the same. the rumor was jdm ecus have slightly more timing and slightly less fuel. no clue if it's been verified. my mpg is the same on the jdm p73-003 or p73-a02 usdm ecu. biggest difference is the 120mph limiter on the jdm ecu

 

Funny because mine doesnt go much faster before it hits redline....w/ the 4.78 FD.

 

?

if you have a jdm ecu they all have electronic limiters

 

It would help if you told us how many gallons you filled up before counting the mileage and then fill up again and see how many gallons you drove on and miles on it.. i usually fill up with 8-8.5 gallons and i get around 250 miles on that and the most i taken it was 290 miles on 8-9 gallons driving it smooth, also i drive easy on the street and on freeway around 75-80mph and this is on a dc2 with sir-g swap (jdm gsr) with low really low mileage.

 

not bad mileage at all I get about 400 a tank give a few here and there in my gsr sedan...barely any stop and go traffic and very well tuned up!

 

ls gets exactly the same mpg... in all car reviews and what not, gsr actually gets 1-3 more then the ls or type-r

in any case i get 32~ average

 

He said he got 20 miles per gallon city. In my gs I get 35 mpg on the freeway.

 

20 MPG??? No he didnt and you dont get 35 in your GS.
