ok im thinkin bout doing a h2b. However, i dont want to do it if it turns out to be like 20 mph. For all you h2ber, how much gas mileage do you get? What tranny are u using and what Ecu. Imma use a gsr tranny btw. Thanks

 

I dont think its that bad especially if your doing a swap. but Im gonna guess 25-28mpg hwy in civic chasis???

 

23-27 mpg mixed city, highway.

 

With my h22 with h tranny, I get 28/34

Might be useful for you.

lol

 

the mileage will hurt a little but the power makes up for it right..lose some to gain something else that's how it goes hahaha

right around 25 city, but with all of that power the question is how will you behave yourself and stay out of it?? I know I can't...

well since you had to call me a "freak" tard..

the op is asking about gas mileage on an h2b... he/she is concerned about gas mileage, probably because gas is so damn expensive now. (even though its getting a little bit cheaper )

maybe it's out of line i am going to assume money is a slight factor of this build. obviously he/she does not want to spend much at the pump. so i am willing to bet this will be a NA h2b.

if i was going to go thru all the hassle of doing an h2b i would sure as hell not put an LS trans on it. i would probably want to take advantage of that power with a nice short gear box like a b16 trans

i maaaaaaaaaay be wrong but i am sure a 2.2 liter engine on a short geared box like a b16's would get a little bit different gas mileage then an h22 trans. i am not saying it will be drastic, i get 32ish on my b16 trans but with a b16 engine, im sure i would get so much more MPG on an ls trans. so unless the engine runs super clean i don't think he will get 28/34... maybe 26-29ish.

think of it like this if your redline is hitting a lower mph (because of the gearing) then your engine will be spinning faster more often... which burns more gas , unless you shift real low all the time of course. but really now who does that?

try it i just played around with it an realized that the h22 trans is only a little bit better then an LS trans
