I'm not sure what intake manifold I should purchase. It's going to be on a high psi setup, stock wastegate on this evo 3 turbo is 14psi, i will have a bosst controller aswell as forged internals. I can get the Skunk2 manifold for $234.99 including shipping. The edelbrock is like 425.00 with shipping. Skunk2 seems to be a good brand, do you think it will have as much of a powergain as the edelbrock?
