dont think there is any difference to injectors tbh the key difference is the turbo... yours is KO3S on manifold and ED30 is a K04 on manifold which is same as S3 and Golf R20 not cheap ive seen them go for about 450-600 pounds then fitting on top which is not straightfoward and a remap my advice would be a simple remap to your current turbo which i believe that can handle upto 280bhp
