Well i have a brand new Quaife for Ls/B16 and im about to buy a transmission. I have a choice between an Ls or B16, what would be the best one for my application? I should have around 400 whp and i will be using 15in. wheels and around 24in. tall slicks. My car would mostly be used for street racing and a little bit of track use. If anyone has experienced both, please give me an insight on this. I did a search and nothing really helped, so if anyone had personally experienced this, let me know. thanx.

for mostly street use, the b16 will be quicker. as for the track, you'll have to have a decent red line to make it through the traps still in 4th gear. around 9000 should do it. maybe 8700-8800. maybe.

I'd definately choose the b16

TurboDANDEE

Wow, thats very surprising. I thought most people would choose the LS because of its long gears. well i have a built head so i could redline all the way to 10 grand, but i rather stop at around 9k. thanks for the info guys, keep them coming.

I have one more question... How does those Pro guys hit 160+ mph with honda tranny's? i know they're not using stock gearings, does anyone know what they use? I read somewhere that Jotech uses ITR tranny's with Quaife, I wonder what they modify to reach 170+ mph.

ls...ick!
b16 all the way...
your slicks can also change on where you finish (what gear).
but yeah b16..
do you need to go 180 mph??(but get to 145 mph slower than the b16...)

TurboDANDEE

Nah, im not trying to go freaking 180 mph, but it would be nice to play around with the Supra's and RX-7's on the freeway and not have to worry about running out of gears. So you're saying that by using 28 tall slicks, those tranny's can go all the way up to 170 mph? that's pretty amazing.

Is this true for most boost applications, or just his? I have an LS and I'm planning to turbo it, and I'll be putting on a new clutch soon so it would probably be the best time to buy a new tranny also... would the b16 be the best choice or should i just stick with my ls? or gsr maybe?

TIA

TurboDANDEE

from what im getting, i think they mean for ALL boosted applications. I have a buyer for your tranny if you're looking to get rid of it.

there is ONLY 3 things I can see an LS tranny being good for.

1)traction in 1st gear on street tires. the 4.26 FD should aid in putting less torque to the wheels and making traction easier to achieve.

2)top speed highway racing.

3)highway cruising at lower rpm's

in all other respects the shorter geared transmissions will make ur car accelerate faster as long and u have traction. can u use a b16a final drive in a GSR tranny? might want to look into that too.

Mr. Softee

b16 tranny has a 4.26 FD as well.

it doesnot. that was actually a typo in the 99 si manual. viren, b18bturbo(i think or someone he knows) has actually taken one apart and they are 4.40 FD's for sure.

B16....... all the way! Seem to be much stronger to me.

jinxproof99

i have one thing to say.

**** A LS TRANNY

thank you.

hondaswaper

with 28" slicks a B16A tranny can go 163mph at 10,000 RPMs in 4th gear.........

this subject's been beaten to death. Think about it

A shorter geared tranny will out accelerate a longer geared tranny - assuming you have traction, all else being equal. The shorter the gear, the higher numberical torque multiplier, which means more power to the ground.

Midwestrider

What motor is this going to be done with?
In my case I looking to a ls/turbo setup.

For reading in the archives most people with ls's tend to go with a gsr tranny, correct?

dustin

LS tranny w/ turbo = ClubSi myth

Midwestrider

I have the needed from searching the archives.

chidoks

Go with a gsr tranny, its not too tall and not too short...its somewhere in between.... With a gsr tranny, you have a happy medium in between...it aids in traction and the acceleration is pretty decent... If you are into hybrid trannies, go with a b16 and an ls fifth gear...

bigTom

shorter gearing=u go faster... its that simple... look at how short all motor guys make there gears... turbo is differant in the sence that u need more top end out of the gears so the gears have to be slightly longer... but to "ls" long

the si tranny has a 4.4 fd... iv personally taken a couple apart

simple4012

I definately would not say that at all. Ls trannies are good for high HP drag cars that simply either cant gain traction or dont want taller slicks...its that simple. IMHO a b16 tranny is the **** until ya talking high hp numbers and 140+ traps. My personal tranny is insane...check this

gsr 1 and 2
ITR 3 and 4
gsr 5th
Jdm ITR 4.785 FD....

MAY GOD HELP EVERYONE IN 3RD AND 4TH GEAR

b16
ls when you have gobs of power
Custom tranny when ya do it right
