Raceonly FD 13B-REW Secondary Rail Step-Up Kit

RaceOnly's Step-up fuel rail kit is considered their entry level kit for the FD RX7. If you want to make more power than factory then this is your first step. This kit allows you to make up to 440 HP (330RWKW) on E85 (depending on the injector size you use, RaceOnly made 330RWKW with Injector Dynamics ID2600X injectors). This kit is designed to link up to your OEM Primary fuel rail, the banjo fuel hose bolts straight to the side of their rail.

You can also upgrade your primary fuel rail later and it will be 100% compatible with this kit. Helps if you decide you only want to do this as a first stage and come back and do a primary rail and injectors later.

This kit also has a GFB Fuel pressure regulator integrated as part of the kit and it lives in the OEM position which means it cannot be seen by the naked eye but its 100% serviceable without having to remove anything. The Fuel regulator supplied in the kit can support 700RWKW of fuel so if you have Twin Walbro 525 pumps (also known as Hellcat pumps) this is more than adequate.
