Hello, boys. I'm currently in the process of rebuilding my n/a engine top to bottom. My first question is- Should I go Nissan as far as rings and seals and gaskets, or am I okay with aftermarket stuff? My second question is-What can I modify for a little extra power on my engine? I was thinking MSA headers and camshafts. What problems would I be running into as far as passing smog and daily driving? I don't expect huge gains and I'm full aware of limitations compared to turbo. Any advice on these and other mods I didn't mention would be greatly appreciated. Thanks in advance!
