Surprisingly Australia is one of the world leaders in this sort of performance modification. Sure Puddy does some great work beefing up a S2000 diff but the bullet proof solution is Diff Technics R200 upgrade. Diff Technics are Australian.
Likewise, one of the best transmission upgrades is by PPG. Guess what, PPG are Australian.
I love what Puddy is doing and if it wasn't for freight I would be all over it. Instead I found a highly regarded Aus diff (and gearbox BTW) specialist and worked with him to upgrade my diff. There is no OS Giken or Kaaz center. The Torsen unit is fine and not the part that fails. I supplied a new crown wheel and pinion and the specialist had new end caps machined and a steel collar turned. The result is a diff that nicely holds the power my car generates. Took 9 months but the results are impressive so far.
This guy look after people in melb? wonder how much would cost to send my diff and gearbox to sydney and back LOL!.

I've been calling around and found a gearbox with 54ks on it from an AP1 in japan. he says its smooth as and he'll swap it over with my one and install for 2000. he said he can also rebuild for 2200. what do i do? he thinks i shouldnt bother rebuilding and the one with 54ks is ok, but i think he's just trying to sell that off. i really want an AP2 gearbox from overseas that has the better syncros and gearing ratios. pff, haven't fixed my diff and im already looking at gearboxes. i hope that the diff can last me long enough to save up and get it all done at once and save on labor cost.

That's so true haha i just spoke with Diff technics and got a quote from them. I will be definitely going with an R200 diff conversion now. The pricing is actually less then what puddy had quoted me (for the stage 4).
And i've been continuously doing research on which is the best transmission upgrade to hold that much power safely, and turns out that the PPG was the best all rounder for street/ strip/ and track! maybe not the best for 1000whp monsters, but that's not anywhere near what my car would be. So i guess I've made up my mind. Save up like a mo'f*cker! lol
btw, what do you mean there is no OS GIKEN or KAAZ 'center' . do you mean the crown and pinion or the actual LSD unit itself?
Yeh i'de love your diff.. but i can't wait 9 months.. I'm actually getting it done in the next few weeks!
When people with Toyotas and Nissans and other cars upgrade their diff it's usually the center they are replacing with a Kaaz or OS Giken or other brand name. This idea often carries over to S2000s. It has a reputation for having a 'glass' diff and people jump to the conclusion that the problem is the center. It's not. The issue is in how the crown and pinion is mounted and unless you upgrade this you are wasting your time (and money).

Awesome. Also, if you want try: Gearbox Logistics (http://www.gearboxlogistics.com.au/)
As i have heard and experienced all positive from them. And YES they do performance cars.

Ahk, thought that's what you meant. Weirdly, the problem with my diff is in fact the lsd unit lol the owner before me must'av thrashed it's mum :L

Ps. Now that we're on the topic of diffs. I'll be making 350-400whp depending on how ballsey I am on the day and how much psi I'll be running- considering it's a stock motor n all. Don't want any trouble. (and yes I know everything in the s2000 engine is forged lol) anyways. Rekon I should get a 4.3 maybe 4.4 FD? I don't care how fast I'll be shifting. But ide be accelerating a whole lot faster yes? Or are the gears too short for the sc to do it's thing?
Centrifugal SCs produce boost proportional to RPM so can be sluggish off the line unless you drop the clutch. A higher ratio final drive could only help with this, however you will be sacrificing top end and fuel efficiency.

That's why i asked. but if i go with something like a 4.3 i won't be sacrificing tooo much top end.. hopefully lol
hmm. I think my diff set up will be:
-r200a diff conversion to include;
-Quaife LSD
-4.3 gear <-- most likely
-Level 2.9 drive shafts from DSS
.. That should last me for a while lol Thanks again for the help Aus
