sorry to be the bearer of bad news. the link to the turbo calculator,in the original post, is broken. ....this one "Turbo Calculator [RB20/25]: Stainless Steel Turbo Manifold for the RB20/25 http://www.turbocalc....php#ss_rb25det"

I'm also looking for head and intake manifold specs for an RB20det, specifically ( port sizes, the angles of the ports, etc) so that I can make an accurately dimensioned 3D model of the RB20det head which can be used for flow simulations. This will be freely available and with proper knowledge can be used to test intake manifold designs or port designs to find pressure drop, intake temperature increases, flow velocity changes. I would also like to the simulation to take the temp and flow characteristics of a turbo into account but I don't think that is as important so that will be added later Ablecoh - have you managed to make a model for the head or intake manifold? or does any one have a damaged/unusable rb20det head that they could contribute to this cause? I am more than happy to share my results, all models derived from my work will be uploaded to grabcad for anyone to download. Thanks!
