I just recently put a b20 with a b16 tranny is my ef sedan. I noticed my mileage isn't the greatest. Just wondering what kind of mileage everybody else is getting in their similar swapped sedan?

 

get a diff trans and keep up on your scheduled maint. and you will see good numbers

 

and a tune!

 

ls with with ls trans in a hatch i get high 20's with 100 percent city driving.

 

-hey D16SiHatch what exact mileage does your ls swap get in the city and also on the highway. Also r u running the 90-91ls with ls transmission, the 92-93 ls with ls transmission, or the 94-01 ls with ls transmission?

 

I have a b16 with b16 tranny and average about 25.. Your probably gonna have better luck with a longer ls tranny

 

its gonna be one or the other hp or mpg

 

agreed

 

thats why boost fits in between both of the choices

 

I get 31-33 mpg driving back and forth from school with my 90 ls swap(motor and trans). It's a mix of highway, and hills. If I laid off the throttle I could get better, but I'm happy.

 

Never got a tank under 30. That was in city and highway. Worse tank I ever got was 30.02 and that was with a 2 day autocross. Mainly got 30-34

 

97 b18c, 4.7 FD in a 90 hf crx. 30mpg with no *****-footing

 

B20Vtec w/ Y1 LSD transmission...24mpg. Highest I've gotten was 30mpg on the highway.

 

it's a 94 b18b1 with a 93 ls transmission. in the city i get around 27.5 i want to say and all highway i think i hit 35. it's been awhile since i've driven the car (it's been in storage over winter), and a very long time since i've had an entire tank devoted entirely to highway driving lol.

 

91 hatch, (93)B18a1, (93)Ls trans, I/H/E,heavy foot = 28city 30highway

 

how ofter does any one flush their fuel system? through the tank and through the booster line?

 

I/H/E?

 

i get 300 miles to a full tank with my b20vtec/gsr trans with headers an exhaust.

 

put a LS 5th gear in that tranny and put a good tune on it. i had a LS 5th in my type r tranny with a H2B in a 97 hatch and got between 32-35 mpg with my foot in it all the time.

 

I know it's an older thread, but I found it interesting and wanted to bump it.
91 crx, b18c1, JDM Y1 tranny w/LSD, 100% stock internals.

100% City: ~28-30 mpg average
60/40 (hwy/city): 38.5 mpg (personal best). That's NOT driving conservatively, just normal driving and some full throttle blasts.

 

LS swap and tranny in a 90 civic wagon, I'm getting low 30s. Motor and tranny came out of a 90 integra.

 

320-350 miles on a full tank with a zc sohc non-vtak and si tranny...!!!

 

b16a with GSR YS1 = 28
B18a1 with GSR YS1 = 30

I'm not ripping on it but I like to keep the RPM's up there. With the b16a I hit vtec at basically every light. Sounds like some of you need a tune up/tune.

 

Nice thread.. If the search worked better I would look for a overall Honda threAd on this. Anyhow those numbers are pretty high for me.. In the 95 lx automatIc I get about 24-27 street

 

91 hatch b16a I/h/e itr intake manifold not babied getting around 24-27 and no tune
