Basically in Lamens terms: Turbo cams allow more top end power, NA cams are more for the Low end to make up for not having a turbo.....Now with that in mind, you take the Intake cam from the NA that is the going to make the powerband in the lower RPMS, and put that in the Turbo.
What is your result?
You are sacrificing some of the Top end power that you had originally from the turbo intake cam but you will get the difference of the NA cam to come into play in the Lower RPMs of the powerband.

When the vavles stay open longer they should let more fuel/air in causing a greater explosion creating more hp/toruqe

So if you are pretty much stock, then you will probably notice a nice increase, if you are looking for a reliable high horse power build stay away. Also make sure the cams are in good shape or you might risk jacking your valves as well as you guides, that could get pricey...

Why wouldnt they? There not forged or anything like that, there made out of the same exact thing as the turbo cams.
But if i was going to replace my cams, i would do it with some racing cams instead of the na cams, Like from here
