I'm looking for a turbo manifold to fit an internally wastegated ihi rhb5 (square flange, 3x3 in flange, 1.75x1.75 opening) turbo, but I have no idea where to look. The flange is different from the common T3, T25, and TE04 flanged manifolds I've seen around, and I don't know where I can find a manifold to fit. Does anyone make manifolds with these flanges? I've seen homemadeturbo.com make an adapter plate to fit one of their STD manifolds, how difficult would that be? Thanks!

I will be posting a GB within the week on custom manifolds. All I need is the flange gasket, and the general overall dimension of the turbo. TIG welded and CNC flanges....IM me for more info...
