Ok, a friend of mine is in the navy and makes parts for pumps and other stuff that involves welding and fabrication. He is a smart kid when it comes to his work and wanted me to ask around to see if i could get him information on turbo manifolds for honda B & D series motors. Hes not a honda fan, but he realises there is demand for quality turbo manifolds at decent prices among the honda community Im guessing it wouldnt be too hard for him to make log style manifolds similar to the rev-hard or drag type designes that already exist. I told him i would ask you all for information pretaining to the desing of a basic turbo manifold and any ideas you had pretaining to how they should be built. . . i.e.) wastegate location (if external). - thanks in advance.
