Hey for my daily driver ive been thinking about a ef hatch with a hf tranny and motor trying to go for the best possible gas milage. any tips?

 

Um...STD with an HF tranny?

 

HF engine and trans
The engine is designed for low end grunt (below 3K)
I'm guessing 40-45 MPG from a light hatch

lol, ouch! Unplug a fuel injector to top it off.

I've heard of just an HF CRX getting 45, and this is from a 300 lb dude with 500 lbs of tools in the trunk.

 

i hear hf's can get upwards of 50 mpg. but remember..the sole purposes of these cars..are to get you from point a to point b as cheap as possible.

damn.. thats alot of miles.
manny

 

not to threadjack...but anyone know what the dx hatchbacks tend to get (mpg-wise)?

not the factory/EPA rating, but what everyone is getting in their stock or mostly stock ef hatches today, after 16-13 years or wear and tear.

 

I get 40 mpg pretty much everytime I fill up my 1990 stock STD. Those later HF CRX's were given a 52 city/56 highway mpg estimate. That's some good ****.

AEM crank pulleys and an unorthodox crank pulley. AC compressor and cruise control removed. Splitfire plugs added. I was able to do 340 miles on 5 gallons of gas cruising at 70mph. Highway miles though. Roughly equates to 68 mpg. I probably made that run about 50 times. Used to drive from Indiana to Missouri a lot.

 

Correction: AEM alternator pulley. AEM doesnt make that crank for the HF, at least as far as I know.

 

how does having a lighter alternator pully and lighter crank pully give you better gas mileage?

please excuse my n00b question.

 

i have a 1989 CRX hf! great on gas but gas prices are high depending where you live, $1.95/gal, to fill up my HF is about $12-$13, and whats weird thats like 6-7 gallons fill up from empty! well, as I say, on a full tank to empty it would equal out to 52 mpg on one tank and i can get about 300 miles! later on all this will change when i get a motor swap!

 

I still got like 28-32mpg with my stock B16 swap w/ Y1 tranny. If I wasn't at 8k all the time.

 

I get an average of 28-30 on my stock 1988 crx DX. I drove on all freeway today and got 35mpg.

 

i get roughly 35-38 mpg in my 88 crx dx.. 360 -370 miles for a full tank.. and thats not hitting the light(empty warning light) yet...

 

lol...i have a 1989 CRX Dx....and i dont have a fuel light....or a shift light...it sucks cuz i cant tell when i REALLY need to get gas heh

A CRX HF will easily do 50mpg combined, if not more.

My '91 CRX Si can consistently do 39mpg combined.

 

yeah,

my 88 crx dx, dosent have any fuel light, is your custom?

 

Well I have a 91 Civic Hatch DX 4 Speed Manual everything stock and I get roughly 35 to 40 mpg and thats with me doing around 70 to 85 mph on the interstate to and from work....

there lighter, means LESS work to move heavy stock pullys, less work, more efficent the motor comes, and puts power to the wheels. sweet huh?!?!?!
