318 rebuild for turbocharging

Well that is a good argument, and in a sense, we are both correct. I did some extended research, It is just a matter of how we measure pressure. Because a manifold pressure of 14.7 (which is sea level on a fair day / and WOT on a NA engine) inside a 10000 ft engine (10 psi atmosphere) would be 4.7 lbs of boost. This is measuring absolute pressure, where we compare the measured pressure to absolute vacuum (0 psi). Gauges we use, however, use 14.7 psi as the starting point upon which all other measurements are gauged. But for us, we would start out at about 12 psi for being at altitude and then the turbo begins to compress that to our desired boost level. I suppose our gauges would be a misrepresentation of the boost level goal we are trying to achieve when we are at altitude?
