Quattro gearbox replacement

[Rosco14]

Hi there, got a 1998 audi a4 1.9tdi quattro AFN 110, needing a new gearbox and I am wandering if a 1998 a4 1.8t quattro gearbox will fit? and will acceleration, top speed be better?

It'll be horrendous with a petrol box.

Dervs only rev to 4k or so, so the gears are much longer to compensate.

Theres a derv quattro box on ebay at the moment though!
