I found this picture on deathmachines.net. I'm not 100% sure but I think this is the 4-cyl ECO Tec engine that Ryan Tuerck from Gardella Racing used in the Formula D Pontiac Solstice ( aka the Opel GT here in Europe) It's basicly a GM Opel engine with some very trick bits on it to make it competitive with the rest of the V8 freak show drift cars. That intake manifold looks awsome. Two chamber plenum, individual roller throttle bodies. That should make a very optimal and responsive setup with the ramhorn turbo manifold.
I wonder what that alu rail above/left of the fuel rail does. coolant manifold for the head ? staged secondary fuel rail and injectors ?
