audi s2 and b5 s4

[audinut]

the more and more i see underneth b5's the more i recognise s2 parts , has anyone actually looked into the actual differences ?

the rear section looks almost identical

[irishs2]

I guess not quite common knowledge but close enough

Parts of the rear are interchangeable, Peter used a a4 quattro as a donor for his 80, fuel tank filler is different though.

You could also "upgrade" a b5 with an locking S2 diff, or torsen.
