I used the 4wd Cossie blues, but they didn't take me far. I acchieved 100% duty succles already at 0.9 bar boost pressure. Now I have a set of greens which also have a nice resitance of ~4-5 Ohm. Next I'm going for more modern Bosch 0280155830 injectors which are already on their way. 40euros each new with a nice spray pattern. The greens are then going for my Escort in build.
