Here's an early 1.8 8v one:

If you're thinking about an 1.8t engine swap then try to find a 16v to begin with as the battery and ABS are tucked out of the way, although the 16v will fit in the 8v bay. The 8v has lower gearing so will be better for acceleration
I have a 16v 6a engine with a leaky headgasket in a B4 that's going for scrap in a few weeks if you want one, you'll have to take the whole car away though.
