You can't run 14psi on a 2871 untuned. And unless you're planning on 450+ rwhp, there is no reason at all for you to use 272's. Going top mount is not cheap. Do your homework. If you're not sure what boost to run then you obviously have not studied enough. If your trying to be "conservative" then buy my 2871 complete setup, bolt it on, and order a rom tune on the cheap for 400hp. If your paying $2-4K for a top mount setup your going to want to extract all of your power from it. Boost is normally always around 20psi with pump gas due to the nature of detonation. Larger frame turbos can push this limit slightly due to the cooler, more dense charge they produce.
I suggest you study up on the facts a little more and come here with more detailed questions we can actually help with. "How much boost do I run?" has been asked a thousand times and there is no correct answer that Zilvia can give you.
