We highly recommend Fuel Injectors from Fuel Injector Clinic. These are what we use at Datsun Spirit, Inc. These injectors are data matched and come with a very comprehensive information sheet, which include the most complete flow matching and latency value information available in the industry. These information takes the guess work out of the equation and makes the tuning process much easier and more precise. The kit consists of 6 data-matched injectors, information sheet, and EV14 terminal kit (you will have to crimp them). Choose the injector size to suit your application.
