Will i pick up any hp switching form an ls6 to an ls2 intake manifold with a 90 mill throttle body on my 01 z06 with just bolt ons. Also is this a good intake manifold for nitrous, and also will it be good for my future plans for procharger?

no dude...the ls6 is better than the ls2...the fast 90 or 92 intake is a much better upgrade, 15 to 20 hp I think

I really doubt you'll see a 15HP difference between a fast 90 and an LS6. Maybe 10RWHP. Not enough of a difference without a cam.

The ls6 ported will give you more at lower end the ls2 ported will give you more on the top end. Foe sure the 90 or 92 or the 102 will out do both but is it worth the diff..

Right. No argument that you'll get more flow from a Fast 90 over an LS6 intake; both unported. But the gain isn't enough to warrant the money, IMHO. Not to mention, the LS6 already outflows the stock unmodified LS6 heads.

I gained 22rwp .... Went from 388 to 410 by switching from my ls2 to a fast 92mm, it was worth the money to me..hahaha

LS2s have terrible IMs when compared to LS6s, if your dead set on getting a new IM then definitaly go with a FAST.

tell him again brother" the fast is a good mod for about $900
