I have read, from a couple of people who have done it, that the stock M42 intake does not flow well enough to make more than 280 or so whp easily. In my reading about of some of the more powerful M42 builds I have seen some nice custom intake setups, and some designs that are known to look better than they perform (such as angled throttle body, sheet metal box intakes).
What have those of you who have high-power (let's say over 300whp) turbo M42s have done about the intake manifold?
I'm gathering ideas to fabricate my own intake manifold so I can make more power once I install my next turbo. I'd prefer to use the stock lower intake manifold section to reduce expense, even if it involves cutting the flange off. A thread like this could become a valuable repository of knowledge for future turbo M42 builders if people with experience share.
