Hi ! I'm rebuilding this 250000Km engine in 2 days. I just wanted to know if we can add stronger things in it ? We'll change the piston rings, bearings , all the gaskets , ect ect. I want it to be at 0 km when done. I have Blue smoke when rev it and a code for a knock sensor . The engine knocks a bit.So, I want to know your sugestions? I'm going TURBO after that. And a 6 speed for the summer no less. I thought about the phenolic spacers ? all vacum ?
