Do you mean 20V as in 1.8T or 20v as in indestructible Audi 20v 5 cylinder from the UrS4/200TQ? The UrS4 motor only mounts longitudinally, so that's gonna make your life a little difficult. The 1.8T runs either transversely or longitudinally, to make your life easy, get one that is designed for transverse mounting (Golf, Jetta, TT). Also, both of these motors run turbocharged, you don't mention it, but it would be silly to run either one N/A.

why would it be silly to run either n/a? you don't seem to think it's silly running a 16v n/a, and hell, a 20v has, (complex math here kids) roughly one more valve per cylinder than the 16v. don't they sell 20v's n/a in europe somewhere anyway? or was the just a rumor i heard somewhere?

The NA 1.8 20V had a whopping 125 HP and was only used for a couple of years. The new 2L version used by Audi has 130 HP and this is with more sophisticated engine management than the 1.8 16V (139 HP in Europe) or the 2L 16V (ABF-150 HP in Europe) had. That is why we are saying that using it NA is not a good idea.

I would use an 020 trans., g60 flywheel, 228mm clutch. I am in the process of doing my 1.8t swap. I was highly recommended by several companies to use the factory computer, so I am going to. The stand alone sys. is quite expensive and will take many dyno hours to dial in at adl. cost. You could use that money to upgrade turbo, exh., cams, etc. The factory computer will do the job well.......
