A/C question
I am getting ready to swap a 20VT AAN into my 1993 B4 Audi 90Q. I have an extra AC compressor from a 12V 90 and was wondering if this same compressor is usable with a 20VT motor? just not sure if theres any difference.

putting an AAN into a B4...
you might want to use a 7A accessory pulley instead of the serpantine belt that the AAN originally has...otherwise, if you keep the AAN pulley and run a serpentine belt, then you should be able to use the 12v compressor with a custom bracket and a 6-ribbed acc. belt. It also depends on which alternator and P/S pump you choose to use. good luck! ;-)
