My brother just blew his diff last night, and we haven't taken it apart yet. Just wondering what the most common problem is. Is it the housing, or the pinion, or what? I've heard housing more than anything else, but I've also heard it could be other things. Just wondering from people who have actually seen or fixed a broken one what exactly the problem was. It broke during a launch, if that helps. We probably won't have time to rip it apart until next week, so if no one knows by then, I'll post my findings.

 

more than likely the pinion

So what causes the pinion to back out, is it something that breaks? or just normal wear from the abuse?

really? Is there a solution to this problem?

yes , dont drive like an idiot

 

has anyone or anyone know of someone that has blown a comptech diff?? i'm thinking of getting one but, still a little skeptical about getting it... doesn't seem like they did much to it to make it bullet proof..

Thats just avoiding the problem. And missing out on a lot of fun and better autox times because you're afraid to launch it like you're supposed to.

Please, humor me, and tell me what "driving like an idiot" consists of. I am oh-so curious to hear this.

 

Does anyone have any reviews on this Spoon S2000 LSD? From what I read, it sounds as if it can take a lot of abuse.

If someone thinks the use of this picture is inappropriate PM me and I'll remove it.

 

haven't seen any reviews on the spoon lsd... go check out http://www.s2ki.com... might have someone there that has it.... cusco also has a few different lsds for the S..

you dont have to play dumb .. you know damn well what driving like an idiot consist of ... and losen up a lil bit cuz it was a joke or maybe you just dont know what sacasm is .....

 

From what I've head, and I could be wrong.. It isn't the LSD itself that is weak, but like ferrall and Mr. Bagel said, the pinion. I'm wondering, now if the pinion is weak, or is it another component that is weak thats cause the pinion to break.

I've actually looked into putting a Ford 9" on it. Waiting to hear back about the cost. He really wants to turbo the car, and I figure, if you never want to worry about the rear breaking again, then a Ford 9" would do it. This is probably not going to happen, but for the right price, it can't hurt to look at. I don't want to change the direction of the thread, but if anyone has adapted a Ford 9" into a independant suspension axle vehicle, drop me a msg of the complications you ran into.

 

why can't quaife step in and solve this problem...

 

lol - why cant honda make a sturdy OEM diff?

Personally, I don't think that the engineers would have thought that the drivers would abuse it so badly.

 

We're not talking about an Odyssey here, you'd think they'd expect that the s2k would be ripped apart. They shouldn't have made it so fun if they didn't want us abusing it

Also the Ford 9" would take too much customization for any shops around here to tackle. I guess domestics and imports just don't mix. So probably the comptech reinforced housing with treated Kia gears is what we're looking at. I'm going to be out of town till Tuesday, so hopefully I'll have some pics of what broke, and a list of what those parts are being replaced with by next week sometime.

I dont know - Honda states all day that they are all about racing, the s2000 was purpose built...maybe they were trying to capitalize on labor when everyone's diff's broke

comptech does make a diff, and also a reinforced diff housing. the housing on the 00-03 s2ks are somewhat weak, and allows it to flex enough for the pinion to back out and rape itself. either the spoon or the comptech diff should work well, but make sure its in a stronger housing. i believe this problem is addressed in the 04+ models.

I believe some of the Cobra "kit cars" use a 9" w/IRS. Pretty cool, disk brakes were on the housing, slowing the axles down, in-turn the wheels. I think it can be done, and might be worth looking into!

 

I took the entire rear subframe out of my car and it would be very easy to fab up adapters to the new mounts. As far as I know there is no Ford 9" with IRS, but there is a Ford 8.8" with IRS from the 1999 - 2004 Mustang Cobra. However you need to somehow ethier modify the diff to remove the universale joints, or convert the outer CV joints to use the universal joints. The universal joints kind of suck, but they are alot stronger than the CV joins in the S2000 (which are basically the weakest design that I know of)

Removing the entire rear sub frame is easier than taking out the differential in my opinion.

The one I saw was on "Car Crazy" or some kind of Speed Channel show. It did use U joints, but if someone would commit to make adapters for the outter hubs, or adapt some Mustang units, it would solve the big power Diff failures.

 

S2000 owners who have super- or turbo-charged their cars, added other mods to improve engine performance, or who just drive aggressively know that the differential is a weak link in the drive train. The additional forces created by FI, clutch drops, and other modifications and driving habits often leads to a failed diff, often in the form of the ring gear being forced out of the back of the pumpkin.

To help reduce the risk of diff failure, Comptech has developed a reinforced differential housing to help retain the ring gear from getting shoved out the back diff cover under the stresses of competition or hard driving. If you have a car with forced induction, this mod is almost a must. If you buy our 4.57 or 4.77 rear gear sets, it is a mod worth serious consideration, especially if you autocross, go on the drag strip, do clutch drops, or just drive aggressively.

yep. Also Spoon makes the same thing as do others (jdm knowledge = Spoon *****). I saw some vid or read some article stating that one of the first things you might want to do if your driving your S so manly (what else is there?) is to upgrade the differential housing. This is mainly why i dont really abuse my S alot for this reason. Any mods done to the car or is it bone stock? If he is gonna go FI lucky it went now and you know now what to expect. Dotn cross bread just get something designed for the car.

 

shiiiiiiiiit.

well, SOMETHING needs to break first. when you drive the car hard to the point where something breaks, would it rather be the pinion or the diff or an axle or driveshaft or the tranny itself?

its "just" stock stuff too right?
once you slap on the R-compounds youre testing everything's durability under some serious loads
