Torsen for Hyper ST?

[Jabe]

I would like to apply my Hyper ST with torsen central diff, but theres a problem.
I have flipped my motormount, so motor is in front and thats why my gearing is restricted to 52t spur.
And so far i have found only 48t spur for Hobao/Ofna torsen... Is there any torsen that would fit Hyper ST and would have spur close to 52t?
I currently have 52/12, but havent made test drive yet, so i dont know how it works.

So you mean spider or torsen - I have a 46T spider centre diff if you want one...

i have spider with 52t spur, but id like to use torsen, but cant find one with that big spur.
as the gearing is limited... so i must use ~52t spur.

Have you seen this? I'm not sure how many teeth are on the spur though.

closes that i can get with that torsen is 48t and that spur is option part.
is there any other marks, that might fit, with big enough spur.

anyone got suggestions??
how about that Losi centerdiff, is that torsen, one that is identical with Fioroni Tractive IV?
