For those that have experience with high horsepower turbo street cars.....
Which tranny do u suggest for a 350whp street driven gsr powered civic??
....and please let me know how you came to your decision. thanks

I had a choice of wich tranny to go with and I went with the gsr tranny.Honestly the reason I did not go with the Ls tranny......I for some strange reason have a notion that the syncros and every thing else is stronger slightly...Probably is not true but gsr trannys are the best in my opinion.. But I heard that since the gear ratios are longer on the LS,its a better bet for Boost...Ohh well I guess I have mixed emotions about both trannys but its all honda parts so either way you win.... boost is neat Erik with a K

Combining the best of both worlds from an ls and gs-r trannies is the combo I would choose, but i voted for ls.

i wouldnt want ls tranny.
Si or Type R all the way!!!!

car will be faster!

Im not saying im right, but wouldnt you want closer gearing? Once you are up to redline you arent going to drop out of boost during shifting right?

dude b18 trannies suck , im looking for a way out . .
i blew my syncros at like 6000 miles and acura gave me a new tranny for nothing . they were being cool , they knew what was up , but if it goes again they wont replace it again i bet.
but the gearing in the type r tranny is the **** .

BlackGSR

What about custom ?

1st gear - LS or ATS - VERY long first gear for traction
2nd gear - LS second gear
3rd gear - ITR
4th gear - ITR
5th gear - GSR

How does that sound?

Bacially, a VERY long first gear so you won't smoke the tire ... followed by a nice 2nd gear (LS or GSR) ... then ITR all the way. GSR for some nice highway driving.

Last I checked, the LS and GSR had the same 1st and 2nd gear ratios.

I might as well chime in. I voted for GSR. Your car is accelerating faster. People say LS you are in gear longer, blah blah--when really your just accelerating slower. Also with the GSR you will stay in boost after you shift, and for the vtec guys, you will stay in VTEC after you shift. Now if its a top speed contest-then LS all the way.

simike

If your car can't spin the tires you will accelerate faster. On the street it doesn't matter what gearing you have you will always spin your tire's. At the track if you are running slicks you still spin, a lot less than the street but that is where the LS tranny can really help take away the tire spin or at least reduce it as much as possible. I would vote LS then GSR and SI. I would try to stay away from ITR unless your all motor then that would be my first choice.

As far as falling out of boost that won't happen unless you have a ton of lag. You may fall out of v-tec but with boost you will hardly notice it nor will the tires ever stop spinning.

well.. here's my dilema. i currently have an ls tranny... but i got someone that wants to buy it.. like today. i was thinkin about doin the gsr tranny cuz of the slightly shorter gearing.. but i love that ls fifth gear. hmmmm....

93LSivic

You can always put in an LS ring and pinion. I am thinking about doing this on my GSR trans. Basically so I can keep up with my friends Supra on the highway--well atleast be able to see the taillights in the distance....

supergreenNA1

if you're talkin about doin the ls final drive in a gsr tranny... that was kinda what i was thinkin.... i'm really tossed up about this at the moment. which is why i started this poll..... but it's even at the moment.. and i'm even seein a vote for a type r tranny????? not with turbo.. no way. hmmmmmmm..

bigTom

heh

dustin

Oh man, not this debate again.

"Less shifting". I like that one.

"Your motor is strong enough to pull the gearing". Hmm, should I load my trunk up with rocks then if my motor is strong enough

bigTom

ls!

because u stay in boost longer!

dustin

Dude, the LS totally complements the spool curve of the turbo!

Xerxes

IMO the only reason to use an LS tranny is for drag racing when you want to be able to finish at the top of third gear without having to shift to 4th, saving you a tenth or two off of your time.

otherwise what's the point in taller gearing? You're effectively decreasing the amount of torque to the ground..

supergreenNA1

damn damn damn damn damn. the ls tranny was winning by one vote... then i get a post like this!!!!!

dustin

On the street with street tires (aka, shouldn't be racing), if you are having trouble with traction you might be a little bit faster with an LS transmission if it changes your effective torque to the wheels enough to keep traction. I mean, it's better to keep traction and accelerate more slowly than spin the wheels and go nowhere.

That said, i'd be hard pressed to find a scenario where the LS transmission gains you any traction. If you're spinning the wheels on the GSR transmission you're gonna spin them on the LS.

And any of those "less shifting" and "keeps you in boost" and "lets the turbo spool for longer" arguments are all absolute BS.

SiRkid

oh gosh.so much bs here.
first off... Si tranny = TYPE R tranny minus lsd.(same ratios)
secondly... you will want that shift to 4th gear! you will be going faster beleive it or not!
look at a lot of drag cars...theyll hit 6 gear in the 1/4...the hks one etc. rally car= super short gearing= faster.
super touring car= short gearing= faster.
F1 car= shorter gears.
LS would be a waste unless your going for top speed....it will do ok.
i would say itr or si tranny with maybe a slightly longer final gear.
look at the jdm cars...at say 60 mph they will be revving at like 4400 rpm or around there..in a race with 2 equal cars.one has shorter gearing one has long..the shorter geared one will beat the longer geared one!!
that is till the the end of the gear.then the longer one will eventually catch up and pass cause the tranny makes it possible to go faster cause of the longer gearing.

i didnt vote, but im going with an ls tranny... It complimenst the torque curve a turbo will create.

by the way, shorter gears dont mean **** as far as making you faster. It has everything to do with the torque curve your engie creates. Like dustin said it will increase the amount torque to the ground....however, it doesnt mean much if you cant put it there.

Mike D

dustin

Might want to elaborate, since that is a very large conglomeration of utter nonsense

Dustin

Type-ARR

by the way you dont know WTF! your talking about.......why do all the type-R guys switch to jdm or ats final drive BECAUSE THE GEARS ARE SHORTER KEEPING THEM IN THE POWERBAND MAKING THEIR CARS FASTER!!!!!

Mike D

what i mean is that with a plentiful torque curve, shorter gears are not needed. And, yes i believe that if you do not need to shift as much, and your engine can support longer gears, there is no need to.

what i meant when i said that shorter gears dont make you faster is that if someone puts an si tranny on a 400whp civic ( an extreme i know, but just trying to make my point) is will be tough to put that power to the ground(hence making you slower).

One more thing: Im not saying that shorter gears DO NOT make you faster, Im saying that for this given application they, IMO, are not ideal. I think i should of been a little more specific. i apologize for the confusion.


Hope i made myself more clear. Correct if im wrong.


By the way, thank you (although you did call my thoughts non-sense ) for replying in a respectful way instead of replying in the "longer gears suck shorter gears rule, you are dumb " fashion that some choose.

Malachi

im a little confused, but this makes it sound like if you have a flat torque curve then you might as well slap a 3 speed tranny on there. Im not trying to be a jerk or facisiouse but wouldnt you want to get into the higher gears faster from an acceleration standpoint?
