Well Im putting a HRC stage 2 kit on my car and was woundering what size injectors would b best if I only have a vortech sfmu, but have no money for a afc or safc right now. Im more then likely going to order them from HRC unless somebody has a better idea where to get them. I was thinking 310cc but im not exactly sure. I wont be altering the boost so i think it will be at 7-8psi. I just dont want my engine running to rich or lean thats all and im new to the whole turbo thing. So just let me know what size and where to get them would be best for me. Thanks
