Project one: Audi A4 B6

My “first” car project – the Audi A4 B6 1.8T Quattro.

Ever since I was young, I’ve had a passion for motorised vehicles. I grew up on a small farm in rural Norway, drove a tractor long before I could reach the pedals and have been living in the garage for the most part of my youth. Friends came by with their mopeds, tractors, cars, lawn movers, go-carts, snowmobiles – well, pretty much anything with an engine really. My first car was a ’88 Ford Sierra 2.0CL sedan for which I replaced the engine three times. The first two I had to change because I had fitted an upgraded cam shaft which caused me to over-rev the engine as it had no such thing as a rev-limiter… It was originally fitted with a carburettor, but I rebuilt the entire car with all the electronics to an injection (EFI) system when I bought a ’94 engine from a friend who upgraded his to a newer 16valve DOHC version. As I started my higher education, I kinda left the passion for cars on hold for 10years or so before I decided to bring it back about a year ago. 

I’ve always wanted a turbocharged four-wheel drive car so I started keeping my eye out for used cars that matched the specifications I wanted. After  a while I found a used ’02 Audi A4 B6 1.8T Quattro which had seen better days…. The turbo was broken, the radiator leaking and a hole lot of other small issues. As I wanted to get to know the car and wasn’t afraid to get my hands dirty, I decided to buy it!

I’ve spent long hours fixing it up and it has turned out pretty good. Lots of good help from friends dropping by is much appreciated!
