is it worth the extra 300-500 bucks? im talking about a b series lsd tranny...ys1 and y1, not aftermarket.

 

yes. no questions asked. enough said.

 

WHOA! it depends on what LSD you're talking about.

Factory LSD cable tranny, right? The only LSD-equipped cable trannies had shitty gearing compared to the J1/S1 that comes out of the JDM Integra Xs-i. Click the link below to compare the gearing from the Y1 LSD to the J1/S1 I was referring to.

Those are Katman's gearing charts BTW. Anyways, LSD is truly awesome - i've got a factory LSD in my 1998 ITR trans. - BUT if it means getting shitty gearing and a 4.26 final drive as opposed to closer gearing and a better 4.400 final drive, I would NOT get the LSD.

What would I do? Get a J1 tranny (the J1 is the ONLY cable tranny that will for SURE have the USDM ITR gearing AND 4.400 final - the Si could be this or the ULTRA-shitty LS gearing with 4.26 final drive) and add an aftermarket LSD later on.

The Honda diffs are nice, but the likes of Quaife, ATS, etc. are better and you'd still have kick-*** gearing to match your newfound cornering ability.

My 7 cents...

As usual, it depends on what u want to do with the car, or what 'group' of drivers you put yourself in..

Everyone I know, including me, would pay that to get an LSD trans, but as stated above, only if it was comparable to the GSR/SI trans.. EF SiR or 2nd gen LS trannies with LSD wouldn't be worth even a straight across swap, imo.. Your number one concern should be making sure that u know which trans you are getting..

 

Does anyone else see my point about the good gearing and getting the LSD later as opposed to getting the worse gearing just because it has the LSD already?

I still stick to getting the better-geared tranny with the 4.400 final and then adding a BETTER aftermarket LSD. Sometimes if you want the best ****, you'll have to spend more and wait a little longer - instant gratificationcan be your worst enemy.

 

I feel that getting an LSD is better than 'optimal' gearing. After all, if you can't get the power to the ground, what is the use? If your FD is tall, then you can simply keep in a lower gear.

 

"better" gearing is a matter of preference. just because you think that you have the god of all tranny's doesnt mean it fits someone else's needs. what gearing you want depends a lot on what you plan to do with the car, where and how you plan to drive it, and what kind of power you will be putting down. there is no "perfect" tranny or else there would be only one gearset.

 

"just because you think that you have the god of all tranny's doesnt mean it fits someone else's needs. "

WTF? Who said - besides you - that I think I have the god of all trannies?

What application are we talking? You act like you can't put ANY power to the ground w/o an LSD - BULLSHIT.

Take a shitty-geared tranny and drop in an LSD and give me better gearing and we'll see who wins in a dragrace. autocross, roadrace, etc.

I see people RAPING others at AutoCrossing events w/o the use of an LSD. Am I saying LSDs are shitty? NO. But I am saying that good, close gearing for ALL MOTOR or nearly-stock applications for VTEC motors is MORE important than having an LSD and sacrificing close gearing.

Look at ANY good all-motor car or company that supports all-motor like SPOON, Toda, Mugen, etc. and they ALWAYS shortern up the tranny somehow - AND then they run an LSD too.. They usually go with a 4.78 FD or 4.929 FD to shorten it even more so than the stock ITR-based gearing.

Does that make any more sense?

 

The JDM YS1 and the USDM YS1 from the 92-93 GSR both have gearing that is relatively close to the ITR.

 

They've got the same as the USDM ITR, but have a shorter 1st gear - 3.3xx vs. 3.2xx

 

Yes I think that they are worth the extra $$. I would go w/the Quaife LSD b/c someone correct me if I'm wrong, but don't they come w/a lifetime warrantee. <U></U> http://www.intercrewautosalon.com

 

Look, I'll say it again - SOMETIMES if you want the best you have to be patient and spend a little more money.

BUY a J1 or S1 from the Integra Xs-i ONLY, or a 1992-1993 USDM GS-R YS1 tranny and THEN add an aftermarket LSD later. The Quaife IS better than a stock Honda LSD - and you'd get better gearing too.

 

anyone know how to convert my GSR stick to an HX auto?

LSD over GEARING? "Power to the ground"?

Getting power to the ground usually isn't talked about in such a general sense, since most are still wondering about which intake is prettier, but running twelves on street tires (drag), road racing, and if my arm is twisted enough, autocross, and i don't even think about 'power to the ground', but in theory u are right about the power to the ground, but not until after 250hp will it be necessary?

About the LSD over gearing, that's absurd.. If u raced at all, u would see that staying in your powerband is the KEY.. if u have higher gears (numerically lower) then u will get USED, lsd or not.. Your car will be trucking along trying to get into the powerband, your exit speeds will be roughly the same, it's the acceleration that will be severely slower..

I'm not saying limited-slip wouldn't help me, but I'm trying to shed light on the power issue.. LSD helps out alot in cornering, making it easier to go even faster thru them.. However, it's not until u are way up there in hp where you NEED limited-slip to keep from spinning the tires around a bend..

I have seen the light, B18C5-EH2 has shown me.. Next mods &gt;&gt; 6G SI trans with Kaaz lsd/ATS fd..

I'm glad someone else sees what I'm saying. LSD trannies are indeed very awesome, but ONLY if the gearing the condusive to acceleration - i.e meaning keeping the engine in it's powerband sweet spot.

That's a great way to explain it HXblur. I've seen too many 1st-gen B16 swaps be SLOW becuse the gearing drops them too low between shifts. Y1 would be nice for BOOST, but AGAIN in a near-stock form or all-motor you want SHORT gears and a nice, short final drive - higher number.

Honda didn't put the 4.400 in the USDM ITR for NO reason, nor did they space the gearing so the revs would not drop below 6000rpms when shifting fast.

NOR did they put the 4.78 final drive in thier pinnacle JDM '98 spec ITR by happenstance - the did some R&D and found it to be better than the 4.400 for acceleration.

EDIT: a thought just came to me. Here's an easy way to show why gearing is important.

Two STOCK Civics with STOCK B16As are going to dragrace. The ONLY difference is one car has a JDM SiRII tranny (same gearing as USDM ITR and 4.400 FD) and the other has a USDM GS-R tranny (taller gears) with a nice Quaife LSD (very good - better than stock Honda).

Who wins? Driver is the same too. Do you think the LSD will allow the GS-R-trannied Civic to jump so far ahead that it will win? HELL NO. The better-geared car will not only jump out nearly the same (both trannies have the SAME first gear), but by the 1-2 gear change the better-geared Civic will pull out rather quickly. With each successive gearchange the better-geared car will PULL and the other car would not catch it until 100+mph.

I won't even get into an auto-crossing contest. The gearing that keeps the engine in its powerband WILL prevail as winner if the cars are driven by the same driver.

What good is it to get the power to both wheels if you're going to BOG or drop way too far down or even OUT of VTEC to power at all?
