Was looking to some inlet manifold designs, and saw many "Hahn Style" manifolds on Ebay. (Mostly Honda's) For a lot less...

I do not know the cilinder distance of these particular engines, but for a ~2l engine it should be pretty close so you can weld an Ecotec flange onto these. (Now where did I see these flanges for sale..) TB mounting should also not be great magic.
Would make a nice, cheap Turbo manifold.
Looking into this myself as a start for a new, better flowing and cooling SC manifold design for a custom RWD application...

Any opinions?
