I'm planning on swapping out my LS tranny for a GSR tranny soon and i want to know what kind of improvement this will net me 1320 time wise?


TIA

 

Your question is way to bland. The only difference would be gear ratios and we would need to know other stuff like setup and how the car performs as in rpm it goes through the lights and stuff like that.

 

Car is a 95 Civic EX w/ Bonestock B18B swap.

Maybe these will help...



Right lane...

stay with the ls tranny. it has longer gear ratio better for quarter mile and drag. the ls tranny is the most desired tranny. any way my ls ran good as ****

 

Wrong. I went from 14.60 to 14.40 with a stock LS swap in a Coupe just by adding a GS-R transmission. You'd like the Si tranny even better. The tighter the gearing, the better the 1/4 mile (aside from having to shift to 5th, depending on setup and slick/tire size).

 

It's all about the gear ratios and your motor characterstics.

Youll usually see LS trannys on turbo motors. The longer ratios help give the turbo time to spool, and a turbo motor has a much broader power curve.

N/A motors have narrower power bands, therefore closer ratios are needed to keep the motor putting down optimum power.

If you have a dyno chart, you can easily find out which tranny(ratios) is best for you from a little math.

in this case... what do you guys think this set up will run?
94 teg
b18b
si tranny
7.5 lb flywheel
6puck rebuilt clutch
homemade intake
5zigen exhaust ( i know this and the intake does sheit all)
assuming the "good" (doesn't have to be the best, but better then your avg joe) driver...
what do you guys think this will run in the quarter mile?
just looking for an estimate because i wont be going to a track anytime soon, and plus, i wont try this on the streets, so its just for a piece of mind to know what i could run...

by the way, do you guys think a 6 puck is too grippy on the streets?

 

14.9~15.2
who knows man..

that's my guess though

 

Go with the GSR. The best one imo for a stock b18B. One of the best modification you'll do.

Let us know when you'll go try it.

 

Yup, I believe 1st and 2nd gear are indentical. But wait until you hit 3rd gear, the RPM's will be much higher into 3rd... first time I shifted into it was I was like "whoa!"... Lots of fun.

 

b16 tranny. close gear ratios. you want that for all motor

 

Alright, you guys are really screwing me up...

Do any of you have either of these setups (B18B/B16 tranny or B18B/GSR tranny)?

I would really like to get some feedback from somebody running this type of setup...

 

I have GSR tran in my B18B1. GSR tran gives you better gasmilage than B16 besides, you don't go to the track or 1/4 mile eveyday do you? I would stick with GSR tran. and i love it......
I beat 240SX, SI, stangs and blah blah...
you will see the gain after you get one in.

good luck

 

Thanks...
Oh yeah, one little thing i forgot to mention. I will not be going "Allmotor" with this setup. I will be "boosting" it in the future...

i have a b16 tranny in both of my cars. 200 hsp na hatch and 500 hsp turbo hatch. everything depends on your tire size(slicks, radials, etc...), where in the power band you are making power, and your rev limit. you want to be at the peak of your power band in 4th gear as you go through the traps(in the 1/4 mile).

 

if you are boosting... should as well just stick with your LS tranny
but hey... GSR tranny can still handle boost, just won't boosting Long as LS tran due to the longer gearing.

so GSR tran with small boost
LS tran with big *** turbo setups

Cool?

 

Thanks for the info...

I'm not going to be running a "Big azz turbo" since the car is going to be both a street/strip/daily driven/autoX Toy.

Thanks...

 

def go gsr/si tranny and drop that ls in a dumpster near you....everyone who said that the ls tranny is good for turbo cars doesn't own a turbo car...ls tranny is way too loOOnnng. the ls doesn't like to shift around 9k and if your running a big turbo it's going to drop out of boost.

 

no offense but this is whatever...
don't you know LS motor can handle up to 8k no problem with stock bottom??
do a search and yes LS can rev higher with proper parts.

i will vote for GSR tran but SI tran.

 

GSR tran will be fine......

if you are selling your LS tran let me know
i might want it for my Drag III later
LS tran is (for boosting long~~)

 

Ugh, this thread again

Why does everyone think that staying in boost longer = faster acceleration. Gears are nothing more than torque multipliers. The numerically higher the gear/fd, the larger the multipier and the more torque you will transfer to the ground. The more torque you put to the ground the more potential you have for acceleration. Gear spacing must match your power band...doesn't matter if you all motor, n2o, turbo, supercharged, Fred Flinstone foot powered. If you have an engine that produces a nice torque curve from 6000rpm up (peaky), then you want "shorter" gear spacing to keep you in the powerband. An engine that produces good torque from a lowly 4000rpm you can get away with "longer" spacing. Gear sizing on the fd should be made with consideration into slick size. Try to find a combination fd/slick that will get you through the traps at the top of 4th gear (usually) and allow you to use an appropriately sized slick for necessary traction fitment. Ex) I know I want to use a 24.5" tall slick for traction and fitment issues. I'm planning on capping my engine at a 8krpm rev limit. Based on the whp I hope to be making I should trap in the =/- 120mph range (I hope ). The only variable to solve for is the fd.

Recap...
* numerically taller gears/fd = potential for faster acceleration...always
* you can not gereralize on which tranny is better without knowing certain characteristics of your engine

 

were talking about tranny's not motors and yes i know a lot about ls/vtecs look at my sig i have two.....

 

Sorry if this is a repost... Thanks for the info...

 

Nah, I actually don't mind the thread itself. It's the <U>tons</U> of mis-information that seems to follow it that I have problems with

 

I have an ls with a gsr tranny in my hatch and it pulls alright. I didn't have an ls tranny before but my cousin does and he did a 14.5 with his stock ls and ls tranny, I don't think it does much
