I'm thinking about going with a Si tranny over the LS tranny. Will it be worth the extra cost or not ? My last hatch with a B18b I just put the LS tranny in and went with that. I'm wondering if the closer ratios of the Si will be noticable/worht extra money. Thanks.

MOST DEFFINATELY WORTH THE MONEY.....VTEC TRANNY ON A LOW COMP LS BLOCK IS GONNA FLY......BE CAREFUL PEOPLE TRY OVERCHARGING FOR TRANNYS LIKE THAT

blackeg

it will help out a lot with acceleration, but keep in mind that you will be screaming where ever you drive, i mean like 5k rpm at 80 mph and your top speed will be like 100 or something low like that. i personally went with a gsr tranny, it was a nice compromise between the ls and b16 trans

If I were you I'd go with either. GSR is the best choice IMO.

I used both a GSR and an LS. I actually perfer the LS, it isn't better for any application but I perfer it when boosted.

If ya want to sell the LS trans, I'll buy it, cause I need another trans for my white hatch and by the way I don't like my GSR trans.

I've read that the GSR and the LS tranmissions are pretty close together without much difference. I doubt that the tranny is at 5k @ 80 mph, I could be wrong but I would think more at like 3.5k rpm or so. Anyone have more input on this ? Don't they top out at like 120-130 too, not that i care about that but....

My buddy had an Si tranny on his LS.
Thing was alot quicker with the B16.

Took me by 1/2car to full-car length everytime.
I'd do it if I was going all-motor.

Jmunk

I'm looking for something that decent speed wise, but reliable so i'm going to stay all motor. I think that i'll go with the B16 tranny unless someone can talk me out of it.

It depends on what your going to do with the car???? Meaning are you going to run it long distance or are you going to 1/4 mile the car ? If your not going to run the car on the track the LS is the way to go but if your going to 1320 the car the SI is hands down the winner ! Combine that with a V-tec head you`ll be a real problem with some secret internal work !

i have a ls with gsr tranny. i am very happy. my frined's got a ls with b18 tranny and he gets annoyed on normal stop and go traffic in cali. i recommend gsr over b16.

JDMFreak

im with 98booted, i rec. GSR over b16 or LS...over b16 becuz b16 gear ratio is too short, and b18b is too long, everyone is correct when it come to boost, b18b is a good tranny but all in all i would still chose GSR tranny, you should have buddy's with GSR or LS tranny setup, ask them to let you test drive or have them pull agaisnt each other...again it all about perferences...good luck on chosing one


if i remeber correctly between LS and GSR, the gear ratio on 1st and 2nd are the same, maybe 3rd too...but the final drive change all of it....please correct me if im wrong

pr_tony_montana

I heard that ls and gsr trannys have the same gears 1 2 and 3? is that correct?

menkio

please search, i just found 8 good threads.

Only second gear is the same as a LS. All the b-series have the same first gear. Ls has a 4.2 final drive which makes all the gears longer than a B16 or GSR(4.4). First gear on a GSR and B16 is the same, its from second and up that are different. Also if you have a b16 tranny you will be running close to 5k at 80mph. Thats where i was when i had my b16 tranny. Now i got a GSR tranny and i cant tell you how happy i am. Its a better tranny all around, plus it has a bigger and stronger diff.

Longer gears are not better for boost.......

&lt;smashes head on desk&gt;

Know what, **** it. I've explained it time and time agian. There are very few people here who listen to anybody with real track time.

A shorter tranny will always be better for accelleration in anything that Honda-Tech can throw at it.

mwieczorek43

Ricey is correct. This has been covered a trillion times.

Last weeks thread about this.. came to the conclusion that the ultimate tranny would be a GSR tranny. with typeR final drive and quaife (sp?) diff.

clemsonhatch

Well for me personally I wanted the longer gears...so yes it's better for me.

don't hurt yourself

I built the car for auto-x and the extra mph in second gear make a difference, I don't have to shift to third.

Well I've auto-xed a lot and in this situation the LS tranny with Quaife is the way to go. By not having to shift it doesn't waste time and upset the car.

The car is as fast in 1st and 2nd and those are the gears I race in so in this case you guys are wrong.

Ricey McRicerton

No, sorry, it's really not. With a properly sized turbo and shorter gearing, you could pull quicker times.

EDIT: You're racing with it, so you know your setup and tracks better than I do. I personally would not choose the LS transmission for any kind of racing, but that's just me. If you like it and it works for you, then I'm happy.

The LS tranny would kill me at the drag strip or if I had to be in 3rd or 4th gear, so I see where your coming from. But one thing that's nice is great gas milage to and from events

My case is unique so wish us luck this year...we're going after the M3's in Street Mod!

Yeah, I know how that goes about the gas mileage (y8 tranny that's still about as long as a LS). Good luck after the M3s.

dohcdelsol93

I have a b18b with si tranny. 4,250 at 80 mph. averages 27mpg city and 22mpg doing 80 down the highway. I know it sound weird but gas mileage sucks at almost 4,500 rpms. As far as perfomance goes it kicks ***.

white4doorsi

Go for it the Si tranny has better gear ratios

clemsonhatch

Our 99 B18B EX Coupe with GS-R tranny gets about 27-30 mpg, I drove to ATL yesterday and for some reason everyone was hauling *** 90-100mph both ways I averaged 28.5mpg

I've had a b16 tranny on my boosted LS for a while now. I hate the LS tranny, the gsr tranny is nice, but the b16 was my favorite. I have run type r trannies before, but would rather run a b16 with a quaife than a stock diff'd type r tranny.

pr_tony_montana

so lets say you have a stock b18b, would going from a ls tranny to gsr tranny drop 1/4 mile time more than .5 seconds? Whats the average.
