what did u want to know about the tubo for your a4?
If there is such a thing as a turbo for the 3.0 v6?
yeah you can buy an aftermarket turbo charger for pretty much any car, but it almost always involves getting the engine re-tuned because the compression change from the turbos.I like hks the best. here's a link tho their website http://www.hksusa.com/categories/?id=1093
and her's a link to turbo kits specifically for your car http://www.hksusa.com/categories/?id=1090
