I have a set of four 13B turbo injectors 550cc (S6 RX7) and I thinking of using them on my FJ. I have been told that these injectors are no good for a piston engine due to the spray patten. Is anyone using these injector on a fj and happy with them? I konw that these injectors are used on alot of other engines but i want to be sure before i fork out the cash of a new fuel rail.
