Up until just a few weeks ago I would have backed that statement... Now I'm rebuilding the bottom end and replacing the HG. N/A-T is not the way to go.... every year I spend working on this platform the greater the number of reasons I have for saying so and the wiser I realize all those who came before me and advised me not to bother trying are in my eyes. High compression and boost on cast internals and a 20+ yo motor are a very bad idea... even if you've got the engine management and fuel down pat.

Forged internals and a much lower CR are the way to go.
