Since your car is already converted for DSM injectors, you can use the DSM ones to your heart’s content. FIC’s or RC’s… It doesn’t matter… I am leaning towards the RC’s being better matched from a flow standpoint but other than that, I think you are good. The FIC’s might even come with a flow sheet so it might be a moot point.
