supercharger worries

So there's a new "friend" hanging out with a bunch of my buddies and I. He seems to be really knowledgeable with engines and was telling me how quickly my blower (Saleen Stage 3 kit from Brenspeed) will destroy my otherwise stock engine. I'm not crazy with the car by any means, so how horribly will this thing affect longevity?

I was told that having the heads "pinned and studded" would greatly improve the situation...but I've never even heard of such a job...has anybody had any experiences relating to that?

Thanks guys!

Yeah I figured its going to happen to an extent, this guy just took a much more alarmist approach to the whole thing. Not that turbos are bad, but I think this guy's a pretty hardcore turbo fanboy Thanks for the reply!
