hey i'm putting a gsr lsd tranny in my ls, i was just wondering if anyone has already done this? and how much they gained?

what do you mean by gained? 1/4 mile race wise? If thats what you mean by gained I doubt there would be a HUGE difference. And yes many people have done that type of swap. Its just a tranny swap.

 

just a tranny swap... ha ha ha your kidding right, whenever some one buys a camero or mustang do you know what the first thing they do is.............hmmmmmmmmmmmmmm let me think... oh yes change the gears in the rear end... i wonder why that is... i suggest you talk to some people that run the dynos before you make another comment like that...

 

welll hmmmmmmmm let me think, thats domestic crap. If you dont trust the guy you bought your tranny from then i suggest you either get it rebuilt or get your money back. I bought a tranny from a guy i trusted, put it in and it ran just fine. So you know, you can put it in and it can run like **** and in that case you got your *** ripped off. Or you could put it in and it can run great. In that case you bought from the right person. But if your so ****** worried about it being fine then just rebuild it. There are many places on line that sell syncros and all that ****. So just rebuild it and get lsd and all that good stuff.

 

no no...the tranny is awesome, the tranny is coming off a superchaged gsr, but he is trading up to a type r tranny, thats why he's getting rid of it, and i trust him he's my mechanic anyways, i was just wondering what other people gained off it... thats all...

 

Get used to shifting into 5th at the track. And be around 4k on the highway.

 

they gained shorter gearing

 

I had a b16 tranny. And the short gearing was nice. But at the same time many high ways around here are 70 so i was about 4200 on the highway. A bit annoying, but for the speed it was nice.

 

there is an ls 5th gear in it already for highway...way ahead of you there....

poor guy .... he knows nothing about import power or even the first step to increase power in an import. seems hes still stuck in the american muscle era. well welcome to the dark side.

but anyways i've swapped and tried every b-series tranny there is. its not that hard, no custom work like when switching transmissions in a domestic crap, i meant car. but anyway you cant expect to feel more power. it should feel faster tho due to the way shorter gears. you might tricked yourself and say that you feel more power but you would just be lying to yourself since the hp comes from the motor. the short gears and faster shifts are make the car feel faster but i hardly doubt that just a LS to GSR tranny swap will put much more power to the ground/dyno.

you have a lot to learn about how to get an import down the track faster. and a tranny swap is not the way to go. dont get me wrong its good you got the gsr trans, its way better than the ls you had. the B16 tran IMO is a better all motor trans. i liked the gsr trans for turbo its not the shortest but i have enough hp to get throught the gears so it seems like a B16 tranny.

so now you know that only SOME of the factors of making a fast domestic and making a fast import are the same. one factor that is good for both ........ <U>TURBO</U>

 

here's some of the other things i already have done to the motor

Act stage 4 clutch, pressure plate
AEM Cold air intake
AEM fuel rail
AEM tru time pulleys
B&M fuel pressure regulater, with gauge
Crower stage 1 cams, might be switching to stage 2's i know a company going out of business
DC Sports 4 2 1 one piece header
Golden eagle adjustable cam gears
GSR obd2 injectors
Hondata intake gasket
lightweight flywheel
Prothane engine mount bushings
Skunk 2 intake manifold

ummm...making any car faster is the same...

more power, more traction, less weight, better drivers

domestic or import

Why the fuel rail and gsr injectors? GSR injectors are the same as LS injectors. Stock fuel rail flows good until high HP.

That's a negative, I was just shifting into 4th at the very end of my 1/4 mile runs (92-93 mph traps). You'd have to be putting down MAJOR power and hitting 120 mph traps to be shifting into 5th at the end of the 1/4 on a GS-R tranny.

But yeah 4K rpm @ 80 mph on the highway is about right, but he said he has an LS 5th so it wouldn't be as bad.

 

exactly. I was shifting into 4th at the VERY end like just before the line.

 

It will just give you a better gearing.

 

buddy with a flow bench dynoed the ls injectors and then the gsr injectors and they are different... you won't find this on the internet or magazines though, because it really isn't a significant amount... but just enough to and a 1 to 2 hp...and the fuel rail just looks soooooo sweet

 

haha very funny. changing injector give you 1 hp to 2 hp haha is it worth it? why dont just boost your ls? and sell your gsr with lsd?

integra injectors are rated at all the same cc...type r...gsr...ls....all 240cc injectors. You didnt gain hp from switching

 

oh, well...i can still say i have obd2 injectors then.. ha ha

Actually you are correct. B16 would have you shifting into 5th.

no it wouldnt...b16 tranny 4th gear ends at 100-103 mph on a b18b..so if youre trapping in the 90's youre still in 4th

 

anybody that makes it to 5th gear before the end of the quarter is shifing way to early and you probably are running crappy times!... unless you've got some serious **** under the hood...and then you know it wouldn't even be street legal
