Slow going

I'm sorry that I haven't been getting a lot of info up here lately.  I have been working on it on the weekends when I can, but work and the holidays are really putting a dent in my schedule.  I have completed the p/s motor mount and the d/s motor mount is about 50% finished.  I'm using a polyurethane engine mounts that I am sure will compress under the weight of the engine, I just don't know how much.  I'm trying to get the engine close to the hood to leave more room for the oil pan.  I won't be happy if it doesn't fit under the hood.  Also I have changed my mind about the turbo.  I'm now searching for a serviceable Holset hy35 with a 9cm housing from a Cummings diesel truck engine.  I think this looks to be a very good match for this motor.  They have been used rarely on Audi's, but with good results.  Part of my reasoning is price.  Garrett = 1300 USD, Holset hy35 = approx. 200 USD.  The savings is almost the cost of the vems ecu or perhaps an lsd transaxle.  Reason 2 is of a surging issue that I keep hearing about with the Garrett turbo that I was after.  Reason 3 is that Garretts aren't really rebuildable, but a Holset is easy and cheap to rebuild. Reason 4 is that the Holset isn't water cooled, thus simplifying installation and allowing the removal of more weight and components from the AAN.  The final reason is that this car is all about taking the less traveled road so....why not.
