Hej Perlos
Jeg fandt noget om vore gearkasser: Klippet fra en Audi side:
Hvis det er for at få en stærkere gearkasse til en s2 har du 3 andre muligheder som nok er noget nemmere efter min mening:

Some Brief History & Torque Ratings
The 5-speed 01A box, fitted to the 3B engined S2, is the same box as fitted to non turbo 20V (7A or NM engines). It's a good enough box but it is officially only rated at 310Nm though it can handle more torque if you want. Obviously longevity in a hard driven 01A box with a modified engine could be an issue.
Next up came the 6 speed 01E (CGR) as fitted to the ABY engined cars. This is rated for 450Nm and is a much stronger box than the 01A. I know of some tuned ABY engines pushing 550Nm thru these boxes without reported problems. The early variants of the CGR had a weak point on 1st gear but that was fixed mid MY94 and the CRB box on the RS2 is identical to the late made CGR. More details on that to follow. Some drivers don't like the lazier shift on the 01E box - it has a very positive feel, but it won't be hurried. Some owners are fitting 'short-shift' kits to the gear linkages on 01E models to counteract that. More to follow elsewhere.
What preceded the gearboxes fitted to the S2 ?
Taking a step back in time to the 5-speed 016 box, as fitted to the UR quattro and some 100/200 models, and we have a VERY strong gearbox indeed. Earliest versions of the 016 had a lockable centre differential which enabled a 50:50 torque split between front and rear wheels. This is the nearest configuration to what the rally cars used for maximum quattro traction in the 80s. The gear ratio spacing is a bit funky on the trusty old 016, but this a supremely strong gearbox with a light and quick shift. The ultimate version was fitted to the rare 'Sport' quattro IIRC and this is what monster quattros like the Dialynx special runs with. The lockable centre diff was deleted when Audi introduced the MB engined quattros in 1988/89 with a revolutionary system - Torsen.
De gearkasser, jeg har kendskab til er 016 boxen i min 200 20V Avant, der har kørt med 369Hp og NOS, samt min Ur-quattro med 528Hk og 600 Nm og ingen har svigtet ind-til-nu.
Det pudsige er, at indgangsakslen fra motoren til 016 boxen er kun 20 mm i diameter og med 24 noter, mens den senere til S2 er på 24 mm og med 23 noter. Altså en noget grovere aksel.
