Best gearbox for high torque engine

I have a v8 t25. I want to improve the gearing as currently 2000rpm = 40mph with 16" 60 profile tyres. Is the flipped Audi box the best candidate ? Is the final drive better than the best standard t25 box? Will it mate to the vw adapter on my engine? What other bits are required? Doea a company provide a full kit for sky conversion installation?

Flipped Audi transaxles don't last, this much is known.
They are cheap its true, but dont like having the "wrong" gears in the oil, the diff lubrication is compromised and they do fail suprisingly quickly.
Anyone who claims otherwise is either deluded or has a vested interest in keeping quiet about the truth.
If you want to lay down V8 power- and I am guessing Rover not Audi or another- you will need either a Porsche transaxle (££££) or a Renault UN1 (also ££££ but less than the Porsche) with the appropriate adaptor plate from kit-car circles but...
the whole power unit ends up being very long, so then you will be cutting the van about to make it fit.
