Also, for what it's worth, the main benefit from a tunnel ram type manifold comes from runner length and flow capabilities. With or without boost, the effects of runner length are the same. Some folks are still saying "turbo intake this or that" but that's all been broadly debunked.
This to say, if you are looking for a piece of jewelry for your engine, by all means find a sweet hi ram set-up. It'll certainly look cool (and I totally understand this). However if you are thinking this intake will make loads more power than another with similar runner length and flow capabilities, then the truth of the matter is, it won't. And if you're turbocharging it, the power is largely dictated by the turbo.
With a stock block the intake manifold will not be the limiting factor in a turbo application. You could get to a 1000 hp with just about any performance intake, once you toss boost at it.
