Blown Diff I need help

[speedracer]

So,

On the way to work this morning my diff broke. I am shopping for an upgraded part. What are your ideas? My car has about 225 RHP. I am currently NA but I may go back to a supercharger later.

Contact Puddymod on s2ki. He has an account on here, I think, but I've not seen him very often.

Definitely contact Ben from Puddymod , he is in Florida.

How did it break on you ?, did it just quit or did it start making lots of noise ?. What kind of fluid do you run ?.

[Looter]

Man... That really sucks ... Good luck with the fix ...

[Rocketman]

Sorry to hear John. I agree with the others about Puddymod for a rebuild, but you might try Jeff first since he's local to see if he has a good one that you can use. I have the old diff from my car sitting on the garage floor that I'll loan you, but it's kind of loose and probably would not hold up for long. Might get you by until your rebuild comes back if you need to use your car. Unfortunately, it's a pretty involved job to swap it out, so if you borrow mine or one of Jeff's, you'll have to do it twice.

puddymod or contact conzetts2k...he did a Nissan R200 diff with axles and a custom driveshaft and I think spent around the same. He's running 512whp with no issues, he can give you the details on what he did and how much he spent.

I have sent a PM to both hard top guy and Puddy mod. So far I have not been able to get them to respond with a price and/or a time frame, After reading various threads on changing gear ratios I have not seen anything that wants me to change from stock. Thanks for the offer on the spare diff Rocketman, I do not have time to change it out twice so I am going to find a good used one or an upgraded one. I will also PM Jeff to see what he has in storage. With the right price maybe a used stock would be the answer and then I could upgrade it if I go back to FI with a new drive train later.

Well this is not a happy time. 3 red cars, none of them on the street. Ummmmm, time to go buy another red car???

Internet flogging withheld at this time due to a couple of broken down Toyotas.

Slight vibration and noise during the polar bear drive. I though it was a leaking exhaust.

It started making more noise on Friday morning and then blew out before I could get it to the shop.

I am not sure what fluid I was running. I think it was stock Honda fluid, I had it changed a week before the polar bear drive so it was still fresh.

Playing odds is not a red car thing, we just keep buying them till we run out of money, garage space or both.

You might want to try a silver this time. We have somewhat better luck with them.

[IRideDumped]

I have a spare ap2 diff and spare ap1 diff. If you need to borrow one.
I was thinking of swapping out my ap1 diff and Trans next weekend for the ap2 Trans and diff. So in that case I'll have 2 ap1 diff's

Let me know if I can help John.

[IRideDumped]

But yeah, silver is better ;-)

There's your problem! Must be the Honda fluid you put in the week before. It's the only logical conclusion!

It's too late for this one but for future reference, you should find out exactly what it was. This diff can be very sensitive to the type of fluid used. Where did you get it from? A Honda dealer? There is no "stock" diff fluid for this car that a Honda dealer carries. They have to get it from their motorcycle division. Honda dealers used to be known for putting in their VTM-4 fluid that was meant for a CRV transfer case. In some cases, this fluid destroyed the S2000 diff in about a week.

I will check on the fluid type. I had it changed about once a year and Curt at C&C motors did the service. So, I am sure Curt put in the right type of fluid and he keeps records on that stuff so it is not likely to be the cause of the problem. I am sure I wore the part out with the turbo and too many fast starts.

From what I know of Curt, this is something he would get right without a doubt.

[Rocketman]

Yes, he would. I'd bet a beer that he didn't make a mistake on the fluid and that John's problems probably stem from his painting the diff red.

Hopefully they put in the correct fluid, it wouldn't be the first Honda dealer to use the wrong fluid like VTM-4.
