      Had to bore to 81,5mm pistons, but rebuild is progressing nicely now. Ended up getting Woesnerr pistons from CS-parts.de



      Also had my local hose specialist make a new return hose for the bomb and steering rack. It was leaking multiple placed. Ended in 70 euro compared to 200+ euro at Audi.


      Next step is to machine the 7A head so it can be fitted to the block.

      Does anybody know where the diamond washer is located at the crank pulley?

      Oh yeah will have a Tommis Billet crank pulley for sale.
      Are you sure about this hose you made? Your steering rack will be making lots of horrible noises! The audi hoses are evil! Not only expensive

      • Why would my steering rack be making horrible noises?

        • Its not the rack actually, it's the pressure building inside the power steering hose.

          I may be mistaken though since this does not seem to be the hose that goes from the pump to the rack, ie not seeing high pressure and therefore you should be fine.

          • Ehm no pressure this is the return line and the hose is a replica of the original hose, so I dont forsee any problems.

                            • Small progress

                              So started my sunday with a little hick up.

                              Thought we had done everything when converting the 7A head, but we missed something:



                              After a bit of drilling:



                              Engine mounts from AK-motorsport ready for the engine:


                              Engine ready to go in:



                              Engine is finally in and also managed to change all the water hoses while it was out:
