99 GS want to put a GSR tranny on it is it worth it will it give me a noticible boost in power?
accleration?
For those that have LS's w/ GSR trannies how much did it shave off your 1/4 mile times?

 

no power increase, but it will accelerate alot faster

 

any LS owners that have done this id like to hear also.

 

For autocrossing, an SI LSD or Type R LSD tranny would be the best due to extreme acceleration in all gears and since top speed isn't necessary. For an all motor car at the quarter mile, a GSR tranny would shave maybe .25 off your time. An LS tranny is best for turbo or supercharger due to the long gears and since turbo will make the LS feel like a Type R.

 

Do a search on this. A lot of poeple doing the swap really like it. Makes the car feel faster because of the shorter gearing. First and second gear is teh same as an ls though. If you're going for boost, then the gsr tranny would be a good choice but if you want to go na then the b16 tranny would be a good choice. Only thing bad about the b16 tranny is the high rev on freeways.

 

i think you will like the shorter gears, a b18c or b16a tranny would definitely be a good upgrade on an LS motor

it's worth it.. i had it on my old setup and i love it..

 

hell yea it's worth it. i just put a GSR tranny in my LS and my car never pulled like that before. 3rd gear is the shitty gear on the LS tranny, with the GSR tranny the car just moves like crazy through all gears

how high would i be revving on the interstate with a gsr tranny if i decided to get it? my ls is already over 3500; i like getting 30-38 mpg on the highway.

 

im at 4200 with a b16...going 80

 

I think it's around 4000-4500 when going 80mph..

 

nah it shouldnt reach 4500 going 80...4500 is around like 85..

damn 4 to 4.5k on the freeway? that sounds kinda nuts.

 

im at 3700-3800 at 80 mph.

 

ya, seriously. My ls im at 3300 @ 80. This is like the one big draw back I see. I personally wouldnt want my ls reving that much. But hell, what harm will it do, 9.2 c/r is nothing.

 

youre only at 3300? my ls is 37-3800 at 80

 

your highway limit is 80mph? in canada, our freeways limit us to 110km/h at most which is like 65-70mph.

for reference sakes, i'm at ~4000rpm at 120km/h so its not that bad.

you probobly need a new clutch. mine did the same thing before i replaced it.

 

The limit is usually 65 and sometimes 70 in the US. That doesn't have much to do with how fast these guys drives...

I think it depends on how much you want to spend on the car. I would rather put the tranny money towards a turbo and would get the SI tranny if anything since it seems to be cheaper.

i highly doubt it. i have NEVER burned out a clutch on any of my cars, and fellow teg owners that have driven my car always say stuff like "i wish my clutch was as stiff as yours", and i dont really beat on my car. ive only adjusted it once in the 20 months ive owned the car, and the freeplay hasnt gone anywhere; i dont do burnouts and very rarely beat on my car. my dad has replaced several clutches in his time, and says mine is just fine.

and how do you explain this? have you even experienced a turbo LS before? have you ever tried the different tranny setups? if not then you're giving out totally FALSE information. no matter the setup, no matter how much power you're making, shorter gears will always accelerate you faster! an LS tranny is NOT best for FI. the longer gears give your motor/turbo more load, therefore you're in boost longer but in no way are you accelerating faster.

your tach is off. a b16 tranny @ 80mph is sitting at 4.5k. get a digital read out from your ecu and you'll see.

that's cause you've got a cable tranny. cable ls trannies have shorter gears(final drive that is) than hydro ones.

good point. while i was driving 75 mph last weekend, there were plenty of asshat soccermoms in their suvs flying by me like i was standing still, going atleast 90, getting about 10 mpg.

You know if the gearing is too low, the traction can be an issue too. I think you have to balance it out with the amount of power you plan to make. For low boost, the LS tranny probably won't have any advantages.

You also don't want to assume the guy is only going to drag race and be full throttle all the time.

yes traction maybe an issue, but there's such things as traction control and slicks. and what advantages does an LS tranny have except for better gas mileage? if you understood or have tried out the different combinations on a turbo'd ls you'd understand. high boost, low boost, no boost the LS' advantage is the same, better gasmileage(and higher top end for those who care to go over 160mph). i would think that my 380whp on pump gas LS would be considered high boost and a good example.

and i wasn't assuming that the guy is going to be drag racing or at full throttle. where'd you come up with that idea? for anyone who's mindset is on performance they'd get the ITR or B16 tranny with their setup. for anyone else who's in the middle such as myself, they'd go with a GSR tranny. gears aren't too long nor too short. if you're gonna granny your car or have over 500+whp then sure go ahead and keep your LS tranny.
