ok i was wondering on ls/vtec turbo all stock internals would a ls transmission work good? or no?
i would say use anything other then a ls tranny, but it all depends on what you plan to use the car for
ok ive heard on other forums use the ls. but my car will be daily driver, and street racing when needed.
lol " street racing when needed ", street racing is never needed, but track street legals are good.
short geared ys1 with lsd. if you will be doing long distance driving do an ls 5th gear too.
ive got an 89 integra xsi, some of them come with the LSD, how can you tell if its lsd or not ? ( for anyone else who isnt sure as well )
easiest way to find out lsd?
option 1
theres a big ass black stamp, or metal stamp that says LSD its usually stamped twice for some reason.
option 2
this is the most accurate way to tell lsd… pull out both axles. look thru the drive hole and you can see all the way through, there will not be a slant bar there.
I used a 96 gsr hydra tranny for my buddies LS/vtec… ran 13.9 in a hatch with whole interior.
If you are planning on going turbo, keep the ls YS1 tranny. Once you get a turbo the longer gears will benefit you with less shifting and you sit in the powerband longer. All you need is an LSD and your set. If you get a short geared tranny like the B16 tranny, you will be spinning your tires all night long.
it completely depends on your powerband!
small turbo/low boost/fast spool you can get away with an ls tranny. it will keep you in the lower rpms.
large turbo/higherboost/more lag i think you want a shorter tranny, so you are never in low rpms and not in boost.
i wouldnt rev a stock ls block under boost above like 7500rpms or so. with that being said i think a large turbo would be a bad choice, limiting the size and rpm range of your powerband.
for higher hp cars, that would be trapping like 115+ i the 1/4 mile, then an ls trans is a good choice, so u dont have to shift into 5th gear.
if my info is confusing, its because its not a straight foward answer, depends on what you want and what you are looking for.
i love my ls trans on my lsvtec, its nice to cruise at 3500rpms on the highway, and im trapping 115 so i dont have to shift into 5th
ok. well i wouldnt have anymore than 300whp on 10psi. so the ls would be fine right? and i heard that the ls revs out at 7200rpms
That is the delema I am having now. I just bought a 92 GS-R Tranny because I lost 5th Gear in my LS Tranny. Then, now I am at the point were I am thinking of upgrading my Motor. I love V-Tec so I was thinkin of a GS-R B18C Head and either my LS bottom or a B20 Bottom. Along with my GS-R Tranny. I am hoping that my LS 5th Gear can be used in that tranny so that I can drive her long distances aswell.
I am at a Decision making bridge and I hate having to have so many OPTIONS…
My set up is a 92 LS Motor running 5 lbs with 450cc injectors and a 255 Fuel Pump. Chrome Tunning.
The motor is still overheating due to the head. So now I have to decide how I want to come back.
My LS tranny is working out great for my 350 whp LSVTEC setup. I’m running M&H 22" slicks, revving to 8300, and trapping at 124mph with plenty left to get me to 130+ mph. If I was trapping at 110mph or less and had no plans to go faster, a gsr tranny would be better than the LS and if I was trapping at 100mph or less I’d recommend the B16. I knew I would always want to go faster, so I never really thought about getting a shorter geared tranny than the LS.:ohyeah: It should be noted that you can overcome some of the gearing issues at the track with different sized slicks too, but if you already have an LS tranny, stick with it IMO.
To answer the original question, I will say that I know this dude local that is running an ls tranny in his turbo car. He makes and can make big power numbers. However, this is a civic we are talking about here, so it’s hard to apply the same physics. Just remember one thing though, a Gen2 LS tranny has a slightly numerically higher first gear combo than an Sir1 tranny. Everyone is worried about the engine falling off when they shift to second. Then again, lets think about it for a second, if you can make over 300whp, then why would you be worried about it falling off? You must be worried that you will fall out of boost? If you fall out of boost that easily, then you may want to consider a different sized turbo. On a second note though, you should be more worried about smoking the crap out of the tires when you shift to second. And having a numerically lower second gear ratio will either allow the clutch to slip a little when you go to second gear to minimize tire spin, or it will drop enough rpm’s to minimize tire spin, but in both situations, you are minimizing tire spin on the gear change.
Of course, if traction is not ever going to be a problem for you, then I would suggest that you get a short geared tranny like the GSR or the SiR.
Good question! There are alot people who sometimes wonder about the same thing.
ok new setup tranmission question. if the ls is good to run on lsvtec, then how good would it be to just run a ls tranny on a b16 motor, and turbo it to somewhere around 300whp. would this be a decent setup to run with?
thanx for all the help so far im asking another question cause im bout to start buyin my setup and just cant quite decide. thanx again, mike
You’ll be pretty damned close to the same ballpark with the B16 as you would be with the ls/vtec. The only difference between the two is that the ls/vtec suppossedly can’t handle the rpm. Don’t let the extra .2 liters throw you off, besides, .2 liters is measely amounts of extra boost at the same rpm. But I say, if you have to turn that much rpm to get good boost, then you should reconsider your turbo size, mainly because you would fall out of boost anyway when you shift. Having to turn and maintain superhigh rpm levels to achieve boost sucks. Then you could always get into hybridizing your turbo combos, but I think that 92notec had some really good information.
so basicaly stik with the ls tranny on the b16 motor.
I haven’t got experience with it, but it just seems like logical shit.
I would take 92notec’s word for it.
In the long run I guess it all depends on how much power you are going to make. I do know this dude (like I said in one of my previous posts) that runs an ls tranny on a hatch that is turbocharged. He does make damned good power. He doesn’t seem to mind it, however, an integra may be an entirely different story. I plan on using the ls tranny for my shit. I think that it would be best to stay in a gear to build boost before going into the next gear. And if you think about it, how much time between shifts could we possibly be talking about here?
On top of all that, if this is a daily driver, f##k having your shit all reved up while going down the highway in and out of boost. Oh, let me guess, were simply gonna cut down the boost for daily driving? What tha’ f##k?!?!?
What’s the worst thing that could happen if you used an ls tranny and it sucks ass? Well, you could always swap it out for the b16 tranny when you get an opportunity. You’ve already got an ls tranny that currently free. So try it first!
ok ls tranny it is b16 motor to come. and yes its my daily driver, and im going to run 10psi all the time.
That’s what i’m gonna do.
Good luck!
