Ignoring the little squabling, i'll share my experience with plugs.
I was running my N/A 2.3 with some bosch platinum plugs, and it ran great. When i did the turbo swap and left the platinums in there, it ran like crap. I was using stock SVO plug wires. (what are those?)
I switched plugs at the nearest autoparts store, the only plug they actually had 4 of, was cheap NGK's. i can say they run better than the platinum ones, but i have nothing else to compare them to, as of yet.
