Hello guys. I drive a Seven replica from the 80s, which I bought last winter. Unfortunately I did not take care that the car also corresponds to the papers. In clear text: in the papers there is a 1.8Ltr OHC, but is installed a 2.0Ltr OHC and the carburettor is not registered either. The last TÜV examiner must have forgotten his glasses on the day of the test. After all, on the engine block is fat “2.0” on it … In spring the next TÜV test is on and the chances, d As I get a badge again, I think it’s rather bad. So I can’t get around a single take-off and transfer, even if it’s painful. So I’m prepared to do this in winter. The bigger engine with Weber would have to be in itself. Worrying about the brakes. After all I can see, the brakes and axles are from a Ford Sierra (front disks, rear drums). The Seven is currently registered with something about 80hp, engine and Verga The Sierra is available with the 2.0Ltr OHC and 100hp and the Sierra is much heavier than my Seven. I have also heard that the TÜV only requires larger brakes if the car is either faster or heavier. It will not be faster, because the 1.8Ltr and the 2.0 OHC turn the same high and the weight does not change because of the engine. Does anyone know and can tell me if I still need bigger brakes?
