    A4 B5 alternator on Audi RS2

    Does anyone know if an alternator from a 2.5 TDI (140a) will fit on a rs2 in place of the 120a ?

    I put a 2.8 30v A4 B5 alternator on my ABY, just had to change the plastic covers over other than that was exactly the same and had no problems with it.

      That's good to know. I got a 90amp off a S6 but tried to swap the pulleys and they're different. Shame that the old pulley got damaged
