The head flows nice on a b16, I dunno about the intake manifold. If anything go to jdmshit.com and get there type r intake manifold, its the exact thing as a jdm type r mani only like 150$ cheaper. You can get like a skunk2 throttle body for 275$ or a gsr for 75$-100$ and the pretty much the same thing. It all depends on your funds and what you're going for. Theres a website where some guy just bores throttle bodies, its all he does, and it's cheap to. For the 275$ you could get a bitchen gsr throttle body bored to whatever you want to, and the guy rebuilds it too.
