i've been seriously looking into getting an s2k for about 2 months or so now, but i wanna make sure i know everything about it before i even think about getting it (dont want any surprises)

but w/ the comptech reinforced differential, has anyone ever seen this aftermarket unit crack or fail? i know a lot of people are switching out to these (especially when doing clutch drops) but how well do they really hold up? and has anyone ever seen a japanese equivalent to it...i know spoon provides a differential which is basically assembled as close to spec as possible, but i know its not reinforced.

 

What about Quaife? I'm not sure if they make a diff for the S2K but if they do thats what I would reccomend. These nothing like a Differential that requires zero matinence and a lifetime warranty

 

i haven't thought about quaife yet...but i remember w/ basically all their LSDs that i looked @ in the past, they were basically bulletproof.

but this brings up another question...i thought that it was the differential housing itself that was weak and prone to cracking...or maybe i'm wrong

 

I believe it's the bolts that can't hold and possibly also the housing

 

Isn't it a comptech differential housing?

 

it's only bearing caps, they modify the stock housing.

why would quiafe make another torsen lsd when the car comes with one from the factory?

People are damaging the diff assemblies by dumping/sidestepping the clutch at 7+krpm's. Of course something will break, that's abuse.

only because i've heard of stock honda LSDs failing, whether in ITR, CTR, haven't really heard of any s2k, but also earlier trannys as well. but honestly, i've haven't really heard of anyone destorying a quaife, the few people that have...well, free replacement.

but vapor, correct me on this, most of the people that are destroying their differentials are doing clutch drops, which i know. but will a 4-5k rpm clutch drop be all that bad? i mean...if the s2k can't handle that in stock trim, then really...i dont know what to say. i know the s2k isn't a drag car by all means, but i'd think it'd @ least be able to handle a few 4-5k rpm clutch drops.

 

i have had two ITR's, and taken both to the track.

13.9 98itr with toda spec b's and stock 14.3 y2k.

i have never heard of problems w/ stock lsd's... the stuff you hear about breaking is from abuse i.e. 7k clutch drops...

you're sayin you haven't heard of problems w/ stock LSDs in b series motors? i'm sure you're not...because there's not a civic/teggy that i've ever seen anyone do a 7k drop with, unless for a stupid burnout. but if you havent' heard of problems w/ stock b series LSDs...then i'm thinking you're not really listening. cuz i've heard of a few stories.

what do you mean by stock lsd's? You realise the LSD is just one component of the entire pumpkin or rear end assembly is it's called. The LSD itself, is not weak, it's a torsen type and is very strong. The same goes for quaife's LSD, it too is an LSD and it would be pointless for them to make a LSD for the car. I'm not an engineer to say the OEM honda pumpkin case is the weakpoint but that seems to be the case. Flex in the case or the mounting points leads to the shearing of the teeth on the pinion gear. Some say it's the design of the pinion/ring gear that leads to this sheering, others say it's the case. Who knows, but for one thing, the LSD is not an issue of being problematic, only the operators of the car. Same goes with the transmissions, I have an '01 and have never had any grinding issues other than making mistakes in shifting. Once you repeatedly grind a few gears, they will grind forever until they stick in gear and you need to rebuild the tranny. There are no magical fluids that help that.

As for the diff being able to accept dumps, yes, it can get away with dumping it at 7krpms but not sidestepping the clutch, you need to preload the drivetrain to minimize any shock it will see from a drag lauch. You can ask any drag racer (not me) how to lauch a car while minimizing destruction to your powertrain, well the only destruction given to is the clutch.

 

all this talk about breaking the differential when dropping it at 7k but what about dropping it at 5500 or 6k.. would that break the differential? just heard that it's bad to drop the clutch in the vtec area.

 

I launch at 4500 and 5000 all the time dumping the clutch, as far as launching in the vtec region, you are risking it but if you get wheel spin the diff should be fine the problem is with brand new s02's I cant get them to spin at 4500 or 5000 and you might hook up at 6000-7500 as well and that would be extreme shock on the diff. Its all about the surface you are launching on as well. Simba, when you gonna go for a spin in my S. Just got my apexi N1 exhaust. Drive my car and youll be sure there is no suprises. Peace 4548268, you know the area code. This is scott turner, i changed my name from 04rsxtypes04

 

- just get a cusco or comptech to play it safe...
- heard too many stories about the rear breaking on this car...
