GSR transmission on an LS motor: worth it?

So i'm still waffling on what the hell i want to do with my car, but i've always wanted more low end response.
I hear a GSR transmission perks things up by increasing rpm's. I tend to drive at low rpms (1.5k-2.25k ) while cruising but like to downshift to kick *** from time to time.
So one question.. are the gears shorter like on a transmission intended for a smaller motor? or do they just run at a higher rpm?
what i'm looking for is a little more pickup, even from low rpm.
will the gsr transmission do this for me?

the GSR tranny has shorter gears so you will feel somewhat of an acceleration since the gears are shorter.
my friend ran a gsr LSD tranny in his 4door LS and he kept up with my b16A civic coupe pretty well. but when i hit 3rd i was pulling. but his LSD and gsr tranny helpd. if it was stock LS then yah he wouldnt have had such a chance.. also he had cams he told me and he got it tuned for fun.

Yeah, i do know that. I know i'm not going to like the 5th gear. I was thinking of swapping that out with an LS gear. Honda shop dude tells me this is easy once you get the tranny apart.. anyone know if there is truth to that? it matters to me because i do a lot of highway.
also kind of considering a USDM ITR transmission with an LS 5th because on the GSR trans, the difference is mainly in the final drive. But i take it the USDM ITR trans is pretty friggin' expensive.. but 2nd-4th would have quite a kick..

Wait a minute. I just thought of something.
I'm looking for the lower gears to be quicker, ultimately. I don't think there is a such thing as a stronger first.. how about just swapping final drives? hmm!
can this be done? a 4.4 out of GSR trans or from elsewhere on a LS transmission? Then i don't even have to get another transmission.. or worry about swapping my 5th.

This will not work as you think it will. You will have overall shorter gears by swapping the final drive, but the gears will still have the same difference from each other. Which means you will still have a TALL 3rd, 4th and 5th gear regardless of the final drive just because of the gear ratios.
Also fyi, the usdm type R transmission gear ratios are the exact copy of a b16 transmission, only with dual synchro on every gear and the LSD. The GSR transmission is overall longer than a b16/type R trans.

buy my usdm 98'' spec gsr tranny with ctr LSD and stg2 clutch kit cheap!!

i am ok with tall 3rd, 4th, and 5th gears.
what i'm looking for is a stronger launch off the line and in general. First and second being the most important. But the only OEM 2nd gear i can find is the type R.. and it looks like 1st gears are the same all around, so why not just keep things simple and not change any of my gears.
and for dcfreak.. i'll pass on the 5000rpm 5th gear idea. i do mainly highway. otherwise i'd just swap a gsr transmission in there and call it a day.

it's bigger, by like 37cc. but it's built for more low end power, so the higher rpm it runs while cruising, the worst off it is as far as gas mileage. that's one reason why you don't want to be going 7000134200rpm at 14mph.

You should just get a LSD instaled and call it a day

i'm not looking for that kind of launch, i want shorter gears without having my 5th rpms be super high at 70mph.
the vtec dohc 1.8 motors are 1797cc and the dohc 1.8 is 1834cc. torque/hp curves are quite different, also.. but that's besides the point!

technically yes, they are both.
but completely different torque curve. ( you should see the ITR.. it's a limp dick until 6000rpm, then it takes the hell off. )
You don't really want the LS running 4000+rpm on the highway. I think in my transmission i have to be at 85, or 90mph to hit that. at 70mph i run at about 3000rpm.
still not clear on wether or not you can swap a 4.4 final drive into a B18B trans.
I searched and found some post in '04 that didn't really make things clear.

i used to have a type r, and my wife has an rs. there's no way in HELL that the rs would walk the itr off the line. the torque curve might look that way on paper, but after driving both, there's no way.

i'm talking about the torque curve of the motor itself.
that's why they add a nutty, high revving transmission, especially at higher gears... so you can pass on the highway in 5th with no prob.

The 4.4 from a B16A tranny will bolt onto the LS differential. The 4.4 from a GSR or ITR tranny will not.
