What I’m planning on doing this winter is to take my nova of the road and rebuild the engine and replace the gearbox. The question is, I want to turbo it! Has anyone turboed a carbed 8v b4, if so what problems am I going to come up against? It’s currently running a Weber 32/34 with a full scorpion system and a Courtney high torque cam. What’s the best way to lower the comp ratio cheaply as it’s not going to run high boost. I was told that a 1.6-gsi head would lower the comp ratio as it has a larger combustion chamber but I’m not sure if that would be enough. Also how do I adjust the timing so that it retards instead of advances?? Any help would be much appreciated.
