Recently I spent some time researching an aftermarket differential to hold the potential power from the s2000. Unfortuantely there is not much out there. At conclusion I was able to talk to Shawn from Quaife about making a differential. They already have done so with the B series race cars (Laskey Racing). The diff will hold 1300hp at the wheels, but they need at least 25 buyers. Of course they will handle all transactions. If you are seriously interested, please PM me with any questions or comments so I can begin to put a list together for them. Turn around time will be 5 weeks and cost 1K each.

 

Is the comptech one not enough for you?

Also, Comptech buys your old one off you. Not a huge market for the stock diff I wouldn't suspect, so if you get a new one without the core discount, then you've got an extra diff that you probably can't get much for.

I'm all up for more people making stuff for the s2k though, so hopefully there is enough interest for a more-built unit.

 

unfortuantely, there have been many cases of the comptech housing also not holding up...

 

would there be any guarantee of refund if the 25 buyers are not met?
<----dont own an S2k, just clarifying for others

 

You should seriously post this on s2ki, there would be alot of interested people.

 

s2ki closed my thread...they are very touchey there. Well Quaife needs to show some type of interest in order to begin the manufacturing process..It will only benefit s2000 owners that want an option.

 

s2ki requires buisnesses to be sponsors to host group buys, as far as 1300 hp, anywhere over four hundred and there is going to be other things that need reinforcement. The diff isnt the only thing that wasnt made for straight line. Where have you seen the comptech housings going out? links if you got them ive yet to hear of it.

so quaife wants to make another torsen LSD to replace the torsen type LSD already in the diff?

 

a bulletproof one. I spoke to torsen a while back and they stated they initially told Honda there would be diff problems. Unfortuantely, Quaife will only go into production with the commitment.

 

Interesting on the s2ki postings. You should drop Tims2k (mptuningusa.com) a line to head up interest from a sponsor. Or pick another one like Chris or Ben at bulletproof.

For 1K, that's the entire housing and gears - given a good choice of ratios, might fair better than buying gears + installation + time putting it back in the car would be more than worth it.

The diff isn't a concern for me at this time, but in the future it might be.

 

its going to come down to a process ofelimination with all the weak links. I understand there will be concerns with the transmission, driveshaft, axles, etc but I am attempting to tackle each one by one. Of course I am not looking for 1300 hp but if it holds that much with Team Laskey then it will hold anything under. S2ki, for a site that I pay membership for, has responded in a very negative manner. I have address my concerns with the moderators and await their response. If they do not then its their loss for their members who continue to struggle with this concern.

 

my question is , are they gonna streghten the housing or just the lsd??? cuz the lsd has nothing to do with the diff failier...

See now this confuses me.

I know there have been failures where the pinion backed off the ring gear sending the pinion through the LSD reeking havoc on the entire assembly.

But can you explain how you came up with, "the lsd has NOTHING to due with diff failure” I'd like to hear your opinion on what is the main cause of differential failure is?

As I stated before, the LSD unit is not the problem or "weak" spot in the pumpkin. It would be counterproductive to repace it with another Torsen type differential that works similar to the stock unit. There is a clear difference b/w the LSD unit and the differential assembly that entails the pinion and ring gear, bearings, and LSD unit. You do realize the stock LSD unit those that Quiafe sells are 1.0 way units, "lockup" on acceleration. The stock unit is the same thing. Why you'd want to have the LSD unit replaced with another similar unit confuses me.

$1000 would NOT include a differential assembly from what I'm assuming. That would only be the LSD unit.

I don't mean to get your hopes down but I think you're wasting your time by replacing the LSD unit. You're best off with having custom flanges made to support a domestic differential assembly.

its the material of the housing that is the weak link... the 04 has improved that by using different metal material.. hope that helps.

 

correct, the material is weak. Both Shawn and Jason at torsen who developed the OEM unit has admitted this. As for the internals, ring and pinion, they can be manufactured through precesion gears. The hard part was finding a diff housing. Only comptech offered some minimal reinforcement with the caps, but that is not sufficient. I just want to show Quaife that there is enough interest so they can begin making the units as they did with the B series. If it doesnt pan out, then so be it...I working on other contingencies

 

I'd be interested as well. I'd like to go to my local Drag strip at least once a year. A nice Quaifie Diff set up would be idele for me.

 

I think what everyone is saying here is that they'd rather have a strong housing first.

Buying a $1000 differential and having it blow to bits because of the pinion and ring gears moving away from each other isn't going to get a lot of people to buy it.

Now, I really want to clarify this part since i'm slightly lost by your posts and I think others will agree with me on this. Is this just the LSD or is it the housing and LSD? I would assume by the price it's just the LSD. That would pretty much give you an idea of why no one wants to commit.

 

housing and lsd.

 

if its the housing, i would really be interested. since i have built over 10 diffs here for the s2000 community in the midwest. that way, i can offer my clients different options for reinforcment.

 

I'll give a as complete and detailed description as I possibly can about this on thursday or friday and help setup a way to get this going through with s2ki's help as well. I think it's best to hold off on questions until then and think of this thread as more of a teaser/get your wallets ready sort of thing

 

well if you guys can get this going then great. I was only trying to assist all of you with a solution. In my opinion S2Ki has become a bunch of whining individuals with no practical skills. Most folks on there frown when you say drag race. Anyway, Rasheed, if you have the time then pick it up from where I left off. I have a car to build...

 

I'm gonna go ahead and give it a try. See how s2ki cooperates with me. I think this can be done, but it's definately going to take up a lot of my time. Good things my pistons still aren't being shipped this week

so for $1000, you're talking about an entirenly new pumpkin (differential assembly) that replaces the ones in the car? Or is this modified stock housing or bearing caps like the comptech modified stock housing? Is the LSD a 1.0 way torsen replacement like the OEM?

Details are necessary if you want people to committ to whatever you're trying Quaife to do.

 

Ok, just got back with some more info. The price has not been set yet and production will take some time.

Will include diff. housing AND the differential. Will be able to hold a substantial amount of torque probably. I cant say exactly how much because they dont know exactly how much. I'll be giving them measurements and everything soon and hopefully they'll reply back with some accurate figures soon as well.

These are replacing the stock housings and differentials. So you can basically save some money on top of these in that you can sell your stock housings to comptech. The pricing of these seems to me like it's going to be very cheap.

The LSD's are not 1way, 1.5way, 2way. More details about the diff itself can be had from here:
http://www.quaifeamerica.com/d...s.htm

The units will use factory ring and pinion gears along with OEM axles and driveshaft. Includes a LIFETIME warrenty even if you race the car as long as it was clearly a defect in the product itself and doesn't involve other manufacturer items (i.e. gears). Warrenty doesn't apply if you exceed the maximum torque appliable (i dont think too many of those are gonna happen ).
