Slightly tuned 2l Nord camshaft options?
doing 2,0 Alfetta engine rebuild, I´m considering some mild performance upgrades. My goal is street engine with only slightly improved performance lets say real 140-150hp on flywheel would be nice. I will use high compression pistons 10,4:1 and lighter conrods, lightened flywheel. But I need some help about the head. I´m thinking about using some hotter cams, the options are Colombo Bariani and Dbilas (german company) cams. I have 4 options: 1)CB cam 280°/10,9mm intake with standard euro cam exhaust. 2)CB cams 280°/10,9mm both intake and exhaust, 3) Dbilas 292°/11mm intake with st. Euro cam exhaust, 4) Dbilas 292°/11mm both intake and exhaust. Any experience with setups like that? Should I also use some stiffer valve springs, or the stock ones should be OK? Thank you.
