I have two fsi blocks and one head. Also have a whole bunch of parts from both engines. These were previously bad engines from a VW dealership. I disassembled them personally, both blocks are in good condition, no cracks or anything. Both rotating assemblies are in perfect condition, except for main bearing 3 on one engine. That was why that one failed.
I bought these to build up both, then put one in something old, mk2 or b3. Decided to rebuild an A6 instead.
For sale as whole package for 600
