On a Turbo KA motor in a 95 240sx running 7-10 psi, what is a highly recommended spark plug for this application. I did a search but didnt find anything on any of the other threads. All i read was to stay away from Bosch, and platinum stuff. I have heard good things about NKG, any thoughts?

NKG is supposed to be good stuff. Go iridium is what most would say, tho ive never had any experience with em first hand.

NGK is what are used from the factory I believe so can't really argue with that

NGK........IFR series......expensive but they're racing plugs. You won't have any regrets.

NGK iridium plugs, or bosch iridium. You want to use iridiums when your boosting to lower the plug temprature to prevent detonation.
