I've searched through the internet as much as I could and I cannot seem to find a place that makes a kit for a 2001 A6 2.7T. I see APR has a 2.7T but in an S4. Think it's possible to get it to work on the A6? Also, at $7249 for that kit, is there a less expensive alternative? Maybe Just buy bigger turbos and better intercooler? This is my first turbo car so I'm not sure what can and can't be done. Thanks.
