In Reply To JECS makes both old & new style Nismo 555cc injectors... posted by Bernie (NoVA) on May 19, 2015 at 08:43 AM
     
Message If memory serves me correctly, JECS makes injectors for many companies that put their own name on the box. Larger injectors are branded Nismo, Tomei, HKS (etc). If someone indicates that it is a JECS 550 injector, then it has been redrilled oversize. Unfortunately these redrills are rarely done well and there are inconsistencies with the flow rates, resulting in a poorly running car.

New style yellow Nismo/Tomei injectors (although they were previously called "555") actually flow at 615cc.
