Hello to my names Paul I drive a ex maw power feature car its had everything done to it even custom blue n black leather trim will post my pics of her in the next couple of days. The problem I have is the engine popped today in a spectacular way! so not good on the other hand I allso own a vw passat sport 1.8 turbo I`m very mechanically minded to a degree. I know there more or less the sam engine bar the blower on the passat, has anyone ever put a passat turbo engine into n a4?????? The thing I`m not to sure is, I know I have to swap the ECU over with the new engine but what about imobiliser n key? any help would be greatful.
