Looks like it would be a decent budget setup.
I would have gone with a JRC and a cheap log mani, but you have what you have. You could always replace what you don't like or doesn't meet your expectations.
My thoughts, you will actually have some some problem with the intercooler, because of the size, the manifold may crack so I suggest you reinforce it now.
What turbo are you using? Injectors? Fuel management, what program are you using to tune?
