Stage One 6.9/7.3 IDI Injectors

The Classic Diesel Design's stage one injectors use factory turbo nozzles featuring our custom extrude hone and edm nozzle modifications to improve fuel flow for pumps running greater than 100cc.

By internally micro-polishing the injector passages and increasing the size of the entrance to the charge chamber, fuel is able to be injected in a greater volume, more quickly.

The volume of fuel will be ultimately determined by the size of the modified injection pump, but the modifications made to these injectors will help to get that extra added fuel into the prechamber in a very short injection cycle which makes for a crisp running, clean idling performance injector that will make less smoke and egts than a stock injector when matched with modified injection pumps.
