Looking for a quick sell for my 4 barely used RC 650cc Low resistance injectors, Part# PB8x-650 that has been modified to flow 650cc/min at 43.5 psi @ 3 bar injectors for $180 shipped. Turns out I don't need it to use with my GT2560R turbo. I don't think you can get almost new RC 650cc injectors...
