Crank shaft compatabilty?

[kwlw]

YES - this is correct - I thought it was hilarious that my first Audi (a KV engined Coupe) has the same crankshaft as the S2 and RS2. Fantastic... Different bearing shells but same crank.

That's why I'm keeping my old good KV (after AAN conversion it became "spares") in the basement .

why different shells

why different shells

Maybe hardened (and purple/blue) upper shells, versus not?

hello, i would like to know if anyone has any knowledge on S2 crankshafts. i need a new crank for my 3B S2 as it is not repairable due to excessive wear on number 5 journal and damage to keyway. Is the audi 200 turbo crank the same, if not what other cranks will fit this engine?
also found that distributor was off a 1985 naturally aspirated audi coupe what other cars had the same distributor?
any help would be much appreciated,
regards,
louis

ive a spare 7a crank thats done 68k if you need one
