It all depends on what Audi. If it was a 5cyl Audi, it was weither a K24 or K26, there should be a little blue tag on the outlet of the compressor housing, it will tell you what it is. FWIW, the K26, feeds a 2.2L motor, to about 7k, and will put out 16psi-20psi. they really run out of steam above that.

Here is a link to the compressor maps.

Those are Borg Warner KKK Turbos for the Audi. They are WAAAAYYYY too small for just about anything. A twin 350 would be spooled at idle and out of steam around 4000. They are not reliable turbos which are known to snap the shafts.

I always thought the Volvos used a Garrett T3 based turbo. Then again, I havent looked under the hood of one in awhile. I have 2 T3 60-trims out of 2 Nissan 300zx's single turbos which would work alot better than those turbos you found. $300 shipped.
