Thats normal, the B16 tranny is geared extremely short.

sounds about right, my friends b16a at around 80MPH is nearly 5k maybe more around 4.5k.

Speed_1

thats right for a B16A, short gears. i am right under 4K at 70mph.

dividedas1

yep yep! everything is okay my friend :-)

raidacaipo

from a single cam to dohc vtec motor may feel pretty powerful at first at the same time the gears are shorter.. especially from the b16 tranny.. its perfectly normal my buddy..

yea it blows but i guess thats the only way honda could make the b16 have some ***** to it.

tdubbebawllin

i got it in a 97 dx and its pretty quick but thanks guys

cehcivic15

my b16 is 3200 at 60mph too its all good man

radestsol

your a ok

yeah highways and hondas don't mix, i'm a little over 4 grand at 70 mph... a 6th gear would be so nice!!

dividedas1

why's it blow? my b16a is just as efficient as my d15b7 was mpg wise...

the only time it will be annoying is if you put a loud *** coffee can styled muffler on there. that would annoy the **** out of anyone, find a smaller oval exhaust (i use a dynomax turbo muffler haha) and my car is oooh soo quiet unless i am pedal to the floor.

b16 trans are sought after because they keep all of our torque less motors in the RPM range that they need to be in, in order for them to be quick at all.

Swap in an integra ls 5th gear set and you can have highway speed/RPM mix of your old setup. That'll get your honda and highway playing nice with each other. OH BTW divideas1 2000siturboR was just stating why the B16 sucks because of its lack of torque. Nothing about MPG, and there is a negligible amount of difference, 2-3 mpg for the d. That is only because the higher amount of power vs. the weight keeps the B efficient, but I felt the d was a bit snappier. If you want real fun though, GSR tranny with an LS motor. Great torque and short gearing 1-4 and a nice long highway 5th.

That's about normal, Unless you get a Ls Tranny for it.

kulo

will a gsr tranny get better mpg?

GS-R tranny wont make that much of a difference, if any. MPG is more affected by how you drive and when you shift. My GS-R swap runs at 3k revs @ ~60mph.

ooooh i caught his comment... how ever this thread wasn't about how much torque a b16 puts out...

the OP asked whether it was normal or not for his b16 to be reving that high while cruising (im guessing on the highway)

and lets be honest here if the OP is complaining about how high the rev's are he is probably concerned with MPG. all i was stating that my b16 gets about the same as my d15 did... i am pulling 32-33 mpg with my short geared b16 trans. while my d15b7 was getting 34-35.

and 2000siturboR was just being a dick... "yea it blows but i guess thats the only way honda could make the b16 have some ***** to it. " what kind of information is in that post? everyone knows a b16 makes about as much torque as a d16z... what i got from what he said is;

yeah it sucks having to be rev'd high (he fails to mention it completely normal and the engine maintains about the same efficiency as it should) and then he takes a stab at the b16... wooo newbs helping newbs..

dividedas1

eh it will make a little bit of a difference. holding a car at a higher rpm over a period of time will use more gas then if it had a longer geared trans with a lower rpm (same speed)

i guess from a GSR/B16 trans it wouldnt make a world of a difference but an LS trans there would be a pretty big difference

blindcurve

Gotcha Dividedas1, yeah that isn't relavent to the message at hand. Thanks for keeping me on track. (smiley) I can't believe you only got 35 high side on your d15b7. On my b7 and b8 I was getting 39.2-45.3. Most of the time I stayed at the 41 mpg mark. The Gsr tranny has the same final drive as the Ls gearset, which makes a huge diff. for mine and my buddies driving style. He has a 2000 Si. Before he was doing like 4000 at 80, now he is at around 3400. Oh, Tdubbebawlin, welcome to close ratio tranny, luckily your engine is built to be high revving.

2000siturboR

what i meant by it is i dont like having to cruise at 70-75 mph on the highway and 4-4.5k rpms. and then to pass someone hell your at 5k almost in vtec. maybe im just a lil nervous about it cause i just drop alot of money in my motor and built it myself.

ps for who ever says then dont cruise at 70-75 mph and go slower. well in my area you need to go at least that fast or risk getting ran off the road or rear ended. i see people in mini vans flying by me everyday at least 90-100 mph .

dividedas1

lol but a GSR trans on a b16 wouldn't be much better.

and an LS trans on a b16 would just be wack. haha

its a honda... it rev's high, thats where it likes it and there is nothing wrong with that.

and 2000siturboR lol i thought vtec was a neccessity for passing people in a honda, lol. atleast if it's naturally aspirated. the switch from the sohc to dohc is a little different, but you get used to how the car will drive.

and yeah my d15b7 was a pos. i beat the living crap out of that motor, i have this "if it aint broke don't fix it" mentality, and i was wanting to swap it till i found the car i have now. honestly i think i may have once got 40-42 mpg but that was just slow driving. like when my moms in the car or something lol.
