I was wondering what type of gas mileage you were seeing.

The D16 in my DD/beater is tired. I want to do a cheap swap, and figured a B20 would be the most fun without having to go to a VTEC motor that requires premium gas.

NVturbo

Plain and simple.....if you are concerned about gas mileage, replace the D16 for another D16.

I'm trying to get some figures so I can make a decision.

A 2 mpg difference vs. a 10 mpg makes a decision easier.

My buddy lost around 5 MPG over his D16Y6 when he swapped it out to a b20.

if u want mpg with bigger motor it all depends on your tune. my friend has b20 with a ls trans and is getting like 25 mpg on a stock p75 ecu. I have a h22 with a ITR trans (H2B) and at 70 MPH i get about 27 MPG beacause i tuned it to run lean at high vac, I.E. low throttle input. My d15b gets like 22 for some reason.... high fuel pressure and big injectors maybe??not sure.

I was getting 35-40 MPG with my ls-vtec. I believe it's in the tune.

89 ed6 FTW!

with my b20v i get right around 15 hwy, 9 in city. plus the walbro 255 might have to do with it also

I get 28hi way dunno city but that's with stock pump 95 Civic Hatch b20z crower 403 head b16 cable trans with cable to hydro adaptor its tuned on a Dinan ECU. Want mpg do a d15z1 swap
For sure its the tune tho my 4dr hiway driving at 16.4 afrs on ls trans.
Gunna afc my eg and lean it out its my hiway vehicle can just turn correction off to haul ***. So if u want an afc would pay for itself in gas. Lol

so why are we under the impression a v-tec requires premium gas?

TurboRob

It only would if u were goin to drive wot but a beater prob just 87

b20 swap is not legal in cali its considered a small truck motor. Can't put a truck motor into a civic.

haha, wtf?

i have a b20b in my 92 cx hatch with a jdm b16 trans cai header and full exhaust with race cat and a few other mods and i get 25-30 mpg hwy and 20 city with stock ecu

Ryank327

Yep, You won't be able to BAR your hatch if you are in Cali like your location says. If you want a cheap B go with an LS.

diazeg92

swap and BAR for b18b1, then swap a b20. if you dont mind doing 2 swaps.

Meister vtec

my friend gets around 28-32mpg in his civic hb b20z with ls trans,he ran a 14.8 with just and intake and type r catback, its pretty praticle to drive daily and pulls hard in all gears,basically I like it,plus you dont have to rev sky high at high speeds

if your REALLY wanna save gas go with a dual point from a ef ive seen it done before

DAmnquickDA

Slightly diff situation but i went from an ls to a gsr in my DA and went from 23-28ish mpg to 35-40 mpg. Yes, you will beat on the b20 more since it makes more power but, in general, a more powerful engine will require less rpm and fuel to get a vehicle of the same weight moving. You should gain mpg imo.

DAmnquickDA

So why are you under the impression that there is a "-" between v and tec? Its VTEC not v-tec or v-tech or vtech. How the *** can people not read a valve cover?????????

your wrong^ its VTAKKKKKK

mooner23

old thread but i've got b20 with ls tranny. I just averaged 35 highway from boise to seattle, and get high 20's city.

the171

cool. big engines with high mpg = gnar.

Rinzler

Why do that? If you get pulled over and you try to say "I'm ref approved" the sticker will say 1.8L but you have a 2.0L. If it's for smog purposes, find a connect or save the D16 for smog time.

diazeg92

your right... at the time i had my info wrong. ignore my above post haha
