Hello, I drive the above car and my colleague has changed something about the fuel and air supply that I have now about 88hp instead of 75hp. The thing is already pulling like sow, nevertheless I would like to have a turbocharger. Does anyone know if I can do even more tuning with this engine, or can I retrofit a turbocharger? A buddy of mine drives your Golf4 TDI with 90hp. He wants to race with me, do I have a Chanze with my nissan BUS? If no what must I change n to be faster than him? I finally have 400 cubic more space than him.
