PS turbo -> IC <- DS turbo (top of IC) TB -> IC <- other TB (bottom) If I read and understood right. I wouldn't think that is right. I would've thought it goes Turbo -> IC -> TB on top half and TB <- IC <- Turbo on bottom half. I don't have any experience with a FMIC, but wouldn't it be stupid to make the air turn 180 degrees only to have to turn it still more to get it to the TB when it could go straight through? With this FMIC, does the DS turbo still ultimately go to the PS of engine like originally designed (via DS TB)? Is this your car and photo? Wouldn't it be easy to know what goes where if you just blow in there and see which opening air comes out of? I am almost sure it has to go as I suggested because the bars and plates or whatever of the IC run horizontally across without any apparent interruption.
