I have 4 used R/C Injectors rated at 315CC each. I was running these injectors as part of an alpine developments turbo kit. I was also using a 5th injector setup that was mounted prior to the throttle body. The 5th injector is 750CC (if I remember correctly), and it only kicked in at high boost pressures. I am also selling this injector and mount setup, but I do not have the electronics to operate the injector anymore. $125 for all 4 R/C Injectors, $75 for the 5th injector and mount, $175 for everything. ALL PRICES ARE O.B.O.
