Re: What's the best transmission for a turbo application? (MiraiZ)
why do people always say "longer times in boost" when referring to ls trannys. that makes no sense. the way i look at it is a shorter geared tranny will keep your rpms higher when you shift, and turboed hondas make more power as the rpms rise so why would you want a trans that will drop your rpms more when you shift. think about it. and if your power isnt rising as the rpms rise you have a bigger problem than gear selection.

B16 & type R gear ratio is the best gearing to bring you back into the power band. I like it because each gear drops constantly. Just because your going through RPM faster doesn't mean your going to drop your times.
Having a bigger tire or taller final drive would help out the b16 gearing. Why do you think V8's have such tall gear ratio, cause they need the balance between torque and gearing(rpm). Of course our motors are high revving, so shorter gearing comes in play.
Balance is still the key, pick the right size tire, for the application.

B16 & Type R motors comes with shorter gears to stay above their powerband, since there max torque is above 7k.
It really depends on your motor setup, but I still think LS is the best for high power hondas.
Question: Are top dawg hondas running stock gearing????

Typical V8's are a totally different ballgame. If you look at a REAL V8 they have close gear ratios. I mean real v8's, small displacement v8's, that actually rev and make power at high rpm. Your right, you want it set up per application, but you can't compare to a camaro or something. They have torque at 2500rpm.
For the question about pros...we run stock type r gears. Of course, once you figure in our tire size it's not really anything like a typical type r on the street. We would love to have closer gear ratios than what we have now, but you can't go 172mph in 4th with anything taller.

Re: What's the best transmission for a turbo application? (tony1)
So to sum this up..
I have a 2000 itr.. soo when i go turbo... i should probadly get bigger rims.. 16s instead of 15s. to help me get traction...
low boost of course....
thanx guys,
Jordo

Probably not the best analogy to use

Re: What's the best transmission for a turbo application?
My concern is traction. Yes short close gears are great. I know Ive always hated my GSR 2nd gear. But when I start boostin' are the shorter gears going to just cause me to spin like a top fuel dragster on bicycle wheels?

Re: What's the best transmission for a turbo application? (Muckman)
Well, I can tell you that I am seriously contemplating getting an ls or a gsr tranny over the Sir tranny I've got now. I'm running 10psi on a ls with a quick spooling turbo. I get wheel spin like a mo fo. I can even break third away and it sucks for quick starts. I bet with some drag slicks it would be a mean combo but on the street tires it's just not working all that well. All this and the fact that I can only rev to 6800. Don't forget that I'm at 4400 rpm when I'm going 80. It's eatin' gas like a SUV.
I wonder who on this thread has actually driven their turbo set up with both trannies? You also have to take into consideration each set up. If you have a big turbo and a high redline I could see using a short tranny because it can help the turbo spool and it will keep you in the sweet spot that is common to high revving engines. If you have a broad power band like with a quick spoolin turbo LS you might want a longer tranny.
Blanket statements about what tranny is better are just short sighted.

"Don't forget, LS trannies are great cause you stay in VTEC longer too. "
Thanks for the insight. What is your point?

Re: What's the best transmission for a turbo application? (glagola1)
Actually I have driven my car with four different types of trannys. B16a,gsr,LS, and LS with GSR Final DRive. b16a is really short I run out of gear faster. And more tire spin with b16a in first gear than any other tranny. I noticed when i raced with other gsr turbos that i would run out of gear first when racing on the highway. And shift way earlier than other GSR turbos. LS is true way longer than anyother tranny i have driven. LS tranny shifting at 8500 is compared to the other gsr still at in the 7000 range. I noticed with the LS tranny i pull harder in fourth while the other car is topping out. And the car boost more psi in 1st and 2nd gear with LS tranny. Now with LS with gsr final drive still have to test only had it in less than a week. I noticed 80mph with GSR is 4400,80mph with LS is 3400rpm, and 80mph with ls(gsr final) 3700. I just have to race other gsr turbo in find out.

Re: What's the best transmission for a turbo application? (tony1)
It depends onyour motor.
8k redline Si/ITR tranny.
7k redline GSR tranny.
I had a 7k redline (ls motor) and a GSR tranny... it was nice and short. Only downsides were the 145mph 5th gear and having to go into 5th on the track. But it was definitely worth it overall compared to a longer LS tranny.

Re: What's the best transmission for a turbo application? (jinxproof99)
Karl let everyone in street class no that ls is best That way when they bog between shifts with the ls trans, it will make it easier for me to get to the next round But seriously you have to find what works best with your driving style, if a shorter ration makes it to fast for you to shift , get a power glide.

yeah, huh....i was wrong......ls is the best!!!!!!!! disregard all my previous posts.
damn, a powerglide would be nice though.

Re: What's the best transmission for a turbo application? (Jordo)
I'm currently using a YS1 cable LS trans...which was sold to me as a YS1 GSR. Arg. It's a street machine..and I'm OK with how 1st and 2nd are on the LS trans, but I'm going to be swapping in jdm S1(b16) 3rd and 4rth gears. I think this will be a very good/simple boosted trans...LS 1st, 2nd for better traction, 3rd and 4th are the only gears that bothered me before. Leaving the LS 5th will be good for cruising highway.... anyone else running this combo? Sound like a good idea without getting to fancy in the trans department?

The whole concept of gear ratios and the trade off between acceleration and top speed is so simple, but people nonetheless ignore it so they can believe what they want to.

How does that work? A USDM YS1 cable transmission was only available in the 92-3 integra GSR.

How many trannies do you go through a year? Jason and Jinx
Do you normally rebuild them with synros,gears or just replace the entire tranny,
The gears can get costly, what companies sell them besides Acura/Honda?
Lookin for a cable B16A Y1 the shortest or S1 pretty short also
Have a cable 93 LS tranny for sell if anyone is interested, 3rd gear grinds, all others are smooth!
How can I get this face off my screen! Thanks

Re: What's the best transmission for a turbo application? (tony1)
Tony is correct..you cannot tell gear ratio by looking at the code...YS1 is both LS and GSR. For me, 1st gear is kinda useless with S1 on the street, same with 2nd...I'm ok with ls 1,2.....I just want to shorten 3rd and 4th...I think this will work well..anyone have any comments for a street driven boosted 57trim t04e.
