I decided through all your intelligence that I would be saving cash piecing together a DIY Turbo Kit. I heard that Cast Iron is a great to holding up as a Turbo Manifold. They are heavy, but they make freakin' Dutch Ovens out of the it! I was looking for a Log Style (ain't really that picky if it's log or tubular, equal length, yadda yadda). It looks like the Log style saves space (?). Would anyone recommend Rev Hard Cast Turbo Manifold? I only plan to make in the neighborhood of 200hp @ the wheels. It'll be a daily driver and I intend to use track time whenever I can.
