I recently swapped out the d16z6 for a jdm b18c and have no mods except for the HKS exhaust that was used previously with the d motor. The downpipe on that exhaust is 2". My tires are 205/45/16 and my camber has been corrected to < -.5 degrees all around.

Under "normal" driving, what kind of mileage do you guys think i should be getting? I'm averaging 20mpgs. Can that be right?

Also, I barely passed the smog ref's inspection registering 88% hydrocarbons...the max is 89%.

Any suggestions to improve mpg and lowering the hc level are appreciated.

well before you ran it through the inspector you should have driven it hard that ma be one reason you hc's are so high

You could easily get 20 MPG if you driving hard and or hitting V-tec, If you drive conservatively you could hit 25

thanks for the replies.

I live about 25 minutes away from the ref and I assure you I drove it hard all the way...5k-8k minimum almost all the way. the car cooled for about 20-30mins for the visual inspection...could that have cooled the cat down too much and reflected those numbers? plus it was 7am.

I drove pretty conservatively for three fill-ups; shifting at 4k at the most. still i'm getting 19-22mpg.

dang my friend's JDM B18C (R) swap has been getting somewhat low MPG as well. I'm not sure if his is that low or not, though. My GS-R w/ 158K miles still gets 30+ on the highway, maybe 24-26 in the city even if driven hard.

i have a 93 CX with a b16a, i/e, 14" alloys. i get around 22 city, 35hwy. i couldnt imagine a b18c1 being that much worse

i got a vx with a b18c1 i get around 30mpg with hard *** driving, but a lot of crusing

i can't figure it out. some people are saying it's because my tires are 205. some are saying my wheels aren't aligned. some people are saying JDM motors drink more....
