Sorry for the language, but my spoken or written Deutch is not very good.
I'm a 40 years old Dane with an '92 Audi 80 2,3E Avant (NG), and a 7A motor and parts getting ready for surgery sometime this summer or fall.
I'm not going for tuning, standard is enough. The Danish Tüv allows a measured 20% more effect from a motorumbau - or 20% more factory specs when the whole motor is changed. I'm still considering if I should upgrade the NG block and go legal, or just change motor and hope the Tüv doesn't notice (higly possible here )
I have a '91 Audi 90 20v Fronti from britain for donor, so all parts are available.The Britons doesn't value the car as much as us, I got the car for 200 euro's and drove it from London to Copenhagen without any problems.
