I've just sent him a pm asking about costs etc.

You beat me to it Tim!
Let us know what Matthias comes back to you with?

Lol! Ok, he said he would need both shafts and centre diff. Cost without shipping would be around 650 euros which is around 830aud or so.
Actually seems pretty good considering the strength of the setup!
I was considering looking around down here to see if a gear cutting place would be willing to do the conversion.
All up it doesn't look that hard to do!

Third gear as well, would be preferable for me, as Rob mentioned too

Hmm, if we got a centre diff from par or ppg we could probably get him to match 3rd to it.
I am happy to contribute to the costs to get this going. If one of you wants to look at investigating what is required and who can do it for us and then come back. I would look to do it but I don't really have the knowledge to explain to vendors what I want except a strengthened 4th gear.
Tim, was that price for a beefed up 4th gear, 4th intermediate, 3rd gear, 3rd intermediate and centre diff gear? thats quite reasonable.
Try Rockability (Aldo) as he has a contact in Sydney who custom makes gears and shafts for him. Its not cheap for one-offs, but it might be worth a short run of a few.
As number 1 priority beefing up the 4th gear and 4th intermediate is at the top of the list for these boxes lol. If you need any spare damaged intermediate shafts or 4th gears I reckon I have a couple laying around to supply whomever/ wherever to take measurements from

If you mean Tom's son Sam, yes. Dunno if Shilac is their surname.
Cheers..

That's just 4th gear Rob. He needs to machine the centre diff slightly because of the larger size of 4th apparently.

Not too sure Aldo, could very well be, I've only met him once and that was to pick up some bits for Mick, I'm certain that he has done some mods for Mick's drag evo boxes though, can't think of the shop's name or even where, somewhere western Sydney.
All great stuff!!
Now that we all have a bit of an understanding of what others are doing out there for gearbox strength, is it worth looking at who can do this sort of stuff locally or should we approach Matthias in Germany for a bit of a group buy sceanario?
Will need to understand who is serious and who is just talking the talk so that we can gurantee him some numbers and he can gurantee us some $$$.

I'm no way near being in a position to start spending $$$ yet nor do I have the time to even try and start co-ordinating something like this (image of "herding cats" comes to mind). What I have been doing is speaking to Andrew Vibert, who is currently looking after the gearbox in Martin Griggs' 380kw atw (with 1100Nm torque atw) EVO3 buggy.
His feedback is Martin's gearbox has sofar held up (and Martin beats the living crap out of this thing - granted it's on dirt, but it's driven HARD) and has the following:
Quaife Centre Diff
Clutch Pack Front LSD (brand to be determined - he couldn't recall)
Stock Internals - cleaned and inspected
He believes things like straight cut gears etc are not necessary on a circuit driven car (like mine) and would be more suited to a drag racing focused gearbox and that he has numerous friends who are still rallying EVO1-3s with stock boxes that are holding up well.
My 4th gear let go climbing the hill at Eastern Creek. I have 400lb/ft of torque on the engine dyno which isn't alot.
A dirt buggy would be more forgiving as the wheels wouldn't constantly be providing traction so there would be more give with the system.
I have also given up on Hillclimbs and Street sprints as I don't want to load 1st gear up for the launches.
Stuff loading it up. Right foot flat on the floor bouncing off the rev limiter and then dumping it is the most gratifying way lol TIC
Shayne how far do you want to go with this upgrade? I reckon an upgraded centre diff is the best 'bang for buck' as it is the weakest link in the stock drivetrain.
The expensive option would be to get a limited slip centre diff from Quaife
The fair priced (but time consuming) option would be to machine out the stock centre diff and convert to 4spider assembly
The most solid but not user friendly option would be to weld up the centre diff, and convert your VC to solid unit. Would probably cost as much as the 4-spline conversion, but then the next weakest link will suffer (probably the teeth on the output shaft??), and so on!
