M52TUB25 Manifold Swap

I was looking at fanatics forums of ppl doing an m54b30 intake manifold conversion on their m52tub25. The question and argument is..which manifold swap is better, the m54b25 or the b30? A guy on fanatics said all u need to do the b30 swap is DISA, intake manifold, and a turner motorsport throttle body adapter plate. Which do you guys recommend? I think Will Turner runs the b25 manifold on all his cars if im correct so is that the better way to go?

I recommend saving your money unless your OE intake manifold has a crack/is damaged.

You will see no gains.
