2001 Audi A4 Quattro Upgrade Recommendations
I currently own a b5 a4 with some minor modifications done. Running a ko4 tune but currently has the stock ko3 installed (this had been already done when i had bought the car) with a full custom exhaust with custom blow off. I'm looking for recommendations on what modifications i should consider doing next to make this car "track worthy". Looking at all areas of the car. Goals for a big turbo build.
