Bring us your D3 Audi A8 and we will convert the vehicle to a 370bhp 520 ft/lbs 4.2 tdi. 0-60 in under 6 seconds, with over 30mpg highway. Price varies with added options (engine block heater, larger turbos etc). A donor vehicle needs to be sourced so anticipate the project time to be about 3-4 months.
