E36 323i 323ti M52 Aluminum Engine Block M52B25 2.5 Alusil 1748450 11111438593

Removed from a 323i imported from Japan. Stamped 1748450. The engine suffered a single piston failure, when I picked it up the cylinder head and oil pan were already off of it. The crankshaft had almost .005" of run-out on the center journal, so I recommend checking alignment on mains.  The journals were clean and the crank didn't show any damage elsewhere (it is available if you are interested).  The main caps are in their proper positions, other than the previous owner removing the oil pan and cylinder head, this engine did not show signs of being worked on previously. There is a nic on the edge of the oil pan sealing surface, otherwise the block looks to be in good condition. I can take measurements or more pictures upon request. I listed some applications with 2.8l engines, because it is likely this is a good core for fixing a euro aluminum M52B28, but you need to look into this, because there may be differences like the sleeve material or the casting. I believe this is a nikasil engine.  The part number 11111438593 (this engine, sourced via VIN & realoem) is an exact match for only single vanos euro spec E36 (07/1994 - 08/2000) 323i / 323ti & E39 (02/1995 - 08/2000) 523i. This block is not the same as any US spec engine, and the casting is different from US spec aluminum Z3 2.8l engine blocks, please do research to ensure you know what you are ordering! This will be shipped with ample protection via UPS or Fedex economy/ground service.
