I just wanted to create a poll here and see what people prefer in the H2B setups. There are many transmissions available in B series and which ones are better for each setup?
My main question here is to find out how short of a gear is too short?
What have you run and what do you prefer?

Is the b16 4.4 final drive tranny too short for the h2b if you are daily driving it?
I actually went with the 99 si (which had ls internals) not sure if it was stock or not.
I rebuilt it and with 1-4th b16 gears (ls and b16 share the same first gear anyway) and kept the 4.266 final drive to save on gas mileage a little and hope.

Gsr trans seems to be the most ideal for a street/strip setup. I know on my h2b with gsr trans with 22 inch slicks I go through the traps at top of 4th gear.

B16 (My bro tested out GSR,B16,Typer and did best 1/4 time with B16 trans with lsd on H2B).

I've been daily driving my h2b with a usdm type r tranny and an act spring less 4puck with out any issues. b16 is hands down the best for an h2b setup. The whole purpose of building an h2b is to go fast, so I never understood why anyone would choose a lesser tranny.

Does the US ITR have the 4.4 final drive? What kind of gas mileage do you get?
I was running an s4 and come to find out its only a 4.266 final drive but it had decent gas mileage outside of vtec.

ya a 4.4 final. Not really sure I havent been paying that much attention, but its decent. Not as good as my y8 but its not bad lol.

When you say that you top out 4th at the end of the 1/4 that would mean about 111 or so @ the top of 4th?

Yes 111 MPH @ 8300 Rpm. If you need more gear then throw on some 23's. I'm getting 35 MPG with this setup. My old motor was an LsVtec with the same trans and I was getting 40 MPG!

B16 is not always the best. Varies between gearing and tire combo. Keep in mind that the OP is also looking for a trans that will have the gearing to save some gas.

B16 4.7 final with Ls 5th

you definately want b16 gearing with 4.4 fd

if your concerned with hwy driving i would imagine you could use an ls or gsr 5th gear although ive never personaly tried it since i didnt drive on the street.

i would also imagine short b16 gearing would benefit you in city driving since it will require less effort to accelerate the vehicle

I am running a b16 trans with 4.7fd and ls 5th and on 24.5x7 i am crossing the traps at 8400

NAH2B

i was running b16 trans, 4.7 fd and 24.5" and crossing the traps @ 10k

of course that was @ 133mph lol

DarKStaR5

lol only reason im worried is stock h23 rods and bolts haha

If you were racing on street tires wouldn't the 4.7 final drive just spin more than a 4.4 or a 4.2 ?

Kozy.

FWIW, I run the two setups through my gear calculator.



B16 box in blue, GSR in red. Slight advatage to the B16 in terms of acceleration, but it really is slight. Personally I would go with the longer ratios, lots of torque in a lightweight car doesn't need close ratios to be quick.

That's interesting. I was curious because the transmission I am using for my setup is basically an LS with b16 1-4th gears, keeping the 4.266 final drive.
