what kind of mileage are you getting? give a quick rundown of your setup, octane used, etc.

s13 redtop, basically stock, smic, ele fan, no a/c, K&N filter= 25mpg city on 93 octane

guitaraholic · 04-30-2009, 01:33 PM

I get around 23-24mpg mostly city driving. But that's getting to the speed-limit assertively lol. I have the MBC set to around 12 psi or so.

SidewayZ-s14 · 04-30-2009, 04:30 PM

DataXUnknown · 04-30-2009, 04:50 PM

Banegraphix · 04-30-2009, 05:01 PM

20-23mpg on 93 octane gutted s13 with redtop and top mount T3 with basically every bolt on Isis makes and ROM tune no emissions at all with 3 inch exhaust. AFRs are around 14 to 14.3 DD and low 13s when im actually on it.

Heck. I have pretty much the same setup.
I fill up my gas tank full and it only gets 200 miles on it before it's at empty.
I'm not sure how many gallons are in the s14 tank 17?

Can anyone figure my millage out? Is it like 11mpg? lol!

blitzsti22 · 04-30-2009, 05:13 PM

get about 24mpg with stock ka24de fill 91 octane

blitzsti22 · 04-30-2009, 05:15 PM

every time i fill my s14 from empty i always put about 12 gallons, i thought i had a bigger tank

GSXRJJordan · 04-30-2009, 05:23 PM

Hahaha you guys.

First of all, this has been discussed MANY times.

Secondly, Wes, you need a FPR - you've got a high flow pump, and are probably running too much fuel.

Thirdly - the S14 takes over 17gals of fuel - ask how I know :/

I run a redtop, GT28R, stock ECU/injectors/maf - my S14 is stripped though, very light, and has full aero (and is pretty low).

I get over 30mpg on the freeway, about 20mpg if I'm on it a lot around town.

undesiredshoe · 04-30-2009, 06:05 PM

17 mpg city....ka24e on e85

guitaraholic · 04-30-2009, 07:29 PM

I still have the stock FPR for now, and my mileage is just fine, and just changed the spark plugs after 35k miles, and they were perfect. Not running too lean or too rich.

clark · 04-30-2009, 08:02 PM

all you guys with sr20s and your 26mpgs and no fpr. are you sure you're calculating with a 15.9 gallon tank? the fuel needle is deceiving

S13 - 15.9
S14 - 17.2

i get about 22mpg city/highway mix

ugh that's horrible

sr20, z32 fuel filter, walbro 255, stock fpr, stock smic, no boost controller, but she purrs like a kitten

LayNLow · 04-30-2009, 08:09 PM

24-26mpg city and 30 highway on my 92 s13 with a 220K mile 95 s14 KA with intake and exhaust, stock bodied with coilovers and a welded diff. 93 octane with up to 10% ethanol. Hate that bullshit, but nowhere around here has regular gas.

^^^Get a new 02 sensor before anything else...

NMs14.5kouki · 04-30-2009, 09:09 PM

im getting 25 to 26 in my s14. blacktop s13 sr, gt2871 .86 ar, with a v mount, 850 injectors, z32 maf, tuned.

ilikebooze · 04-30-2009, 09:11 PM

I get dick for milage until i get a proper ecu. Im running a s14 sr20, 272 race cams, BC valve springs and retainers, hks exhaust, blah blah. All i know is that it runs pretty rich. Hell, my rear bumper is gettin pretty dirty from it. Thats what i get for running agressive cams on a stock ecu

240s4life · 04-30-2009, 09:48 PM

^what kind of injectors do you have?

singlecamslam · 04-30-2009, 09:55 PM

I get 70MPG.....

On my scooter. And around 25 on a s13 redtop with s15 turbo. Hey GSX Jorden, if you have an after market Fuel Pump and an after market FPR, do you set it at 43 PSI with no vacuum right?

I LUV MY S13 · 04-30-2009, 10:02 PM

20-24 stock sohc...highway mpg is shiitty ha

*hOngsterr* · 04-30-2009, 11:29 PM

what common things
can cause poor gas mileage.

MandTPhotography · 04-30-2009, 11:33 PM

^ With this guy.

I get like 18 in the city and 28 on the highway....wtf.

S13 blacktop, walbro 255, T25 @ 15lbs, FMIC, 3" turboback, etc;.. It's tuned as well.

thesimpleS13 · 04-30-2009, 11:37 PM

i can't really give a definite number, because I'm really not sure. But just this past week I got 304 miles to a tank, and that was including a drift event.... SR btw.. lol mostly stock with 3" exhaust, test pipe, and downpipe...

95KA-Turbo · 04-30-2009, 11:41 PM

I get 24-26mpg in my 97 240 with S14 SR, HKS intake, tube mani, 3" elbow/dp/cat/NA Trust DD, FMIC, on 10-12psi using 93. I get way better gas milage on long trips, like 30mpg.

My new DD (96 Accord) gets 30-32mpg without even trying, haha, and it takes 85.

aoiken3 · 05-01-2009, 12:12 AM

i get like 10 or 20 more past the 300 mile mark. so that's roughly 25 mpg everytime. i wish it could get better but its better than a lot of other cars out there tho

MrChow · 05-01-2009, 02:39 AM

Stock KA 184k miles. 3" exhaust, intake and jwt ecu
