Ask Ranjo
His was the ghetto setup. He did all the works himself. Welded and fabricated his own parts. I thought the manifold was a joke when i saw it. I'll assume a few of the parts was his own from a previous project.
He put the project on hold for family change, so im not sure of it's durability.

^well, you can put one on for looks. It will introduce more lag if you're sticking with stock psi.
I think ryan hit it with his specs, but don't forget the AFC tune also.
