Carlos, take a look at HPF's website again for that Powerhouse manifold... it got one really nasty review:
"Exhaust ports are egg shape and will not seal with factory gasket. The small holes in manifold, that help line up the manifold to the head are so sloppy they alow the manifold to move around more than 3/16". Burnt up the factory gasket in less than 200 miles. Factory gasket does not even match the manifold. Stud holes for the turbo and the wastegate were drilled thru to the inside of the exhaust runners and alow exhaust to leak past the studs. I have spent hours on the fabication of the down pipe, wastegate exhaust and the intercooling piping, all for nothing and to have to start over."
I was thinking of getting that one but now I don't think so.
