RC 550cc injectors Peak & Hold work in SR20DET? (searched)

[Rikter]

Hey folks,

I come to those in the know for another help question. I will be running a sr20det (black top... or possibly redtop.. not sure yet) and a guy is selling a set of Peak and Hold RC 550cc injectors. I'm unaware at the moment if they are top feed or side feed. If they are side feed all is well but if they are top feed I'm aware I'll need to get a fuel rail to make them work. Does anyone know if an SR20DET requires peak and hold or saturated?

Thanks,-Rik
