    hello,

    no the rail and injectors are missing,
    but there was cheap-good used Audi s4 items-Bosch 0 280 150 951

    what an engine and the car on hillclimb video, great.
    why putting injector so far, what's the benefit versus on throttle bodies ?
    is the head still for sale ?

    the further away the injector from the valve the better for high rpm performance, fuel has longer to properly mix with the air flow, probably also introduces a small charge cooling effect, look at all the old cosworth DFV engines or the CanAm V8's they all had injectors either external or at the ends of the trumpets
