i just ordered the turbo setup, going to use the compressor and chra from my old 60-1/p-trim hybrid, but on a 5-bolt ford-style T3 turbine housing with 30mm internal wastegate. Im going to give this "ultimate internal wastegate" a try from atp turbo http://www.atpturbo.com/root/releases/release103105.htm

i have dual external wastegates on the FD and they are a pain in the ass for multiple reasons. I believe a well designed internal wastegate can outperform an external. the fact that no factory cars come with an external wastegate should tell you something. the only downside is it wont be truly divided. but i can make the manifold with super short, small runners, and keep them divided up to the flange at least. low volume should help with spoolup
