Alpina M52 / S52 3.3 / 3.4 L crank

[BenGerman]

For sale is a original Alpina 3.3 / 3.4L / 94mm crank, as used in the Alpina E4 & E5 engines in E46 B3 3.3 / 3.4 and E39 B10 3.3 / 3.4 as well as the Roaster S.

The crank is ideal to build a stroked M52 with 87mm bore, around 300hp, a recipe that works well for Alpina in those cars.

The crank was stored upright and covered in oil, the pictures were taken before I put it in the M52 block for overseas shipping.

This is super cool. Do you have the special vibration damper that goes with it? I don't know that it would be balanced properly without it. Here's one listed by a shop in Germany, but of course they won't sell it without an Alpina registration. Alpina part number 1123101.

Some interesting trivia: The crankshaft is probably made by ThyssenKrupp. The vibration damper is made by Winkelmann (stamped as Palsis Schwingungstechnik if made before 2002).
