Well yes and no...
The intake manifold will be designed for top end power so you would see the best gains with a turbo that could flow enough at high RPM. It would still give benifits to any turbo by raising the powerband.
The exhaust manifold I am not exactly sure. I am still doing alot of research regarding the design, benefits and drawbacks. I think the exhaust would help regardless of what turbo you are using.
Headwork would not be needed but you would see bigger gains with a well ported head to allow more flow.
The CFD modelling helps out with seeing the flow in the intake manifold and ensuring proper filling, distribution and keeping the flow as unrestricted as possible. The exhaust portion can utilize the CFD stuff much better because you can actually see the TQ being exerted on the turbine at different RPMs as well as pressure, velocity, etc. Im not an expert at this stuff but I am getting much better with it.
Another thing I have been toying with is Finite Element Analysis stuff. All of this engineering stuff gets very interesting and really cuts down on prototyping time. Instead of creating 5 products and getting close to what is good you can get it close without even making one test item.
