Description
This fuel rail conversion kit is compatible with the Version 5/6 JDM STi EJ207 and Twin Turbo Legacy GT-B EJ208. It converts the OEM side feed fuel injector setup to top feed, allowing the use of high flow fuel injectors (not included). The fuel rail injector bores are 14mm ID. Each rail features a large internal bore to suit even the most fuel hungry engines. They are CNC machined from solid 6061 aluminium, black anodized, and laser engraved for a high quality surface finish. All 6 fuel rail ports are tapped with 8AN ORB (3/4″-16) threads.
Machined phenolic mounting spacers and washers are included to completely isolate the fuel rail from heat transferred from intake manifold and mounting bolts. The four included machined injector seats press into the intake manifold and seal air tight. They are anodised and laser etched and are designed for 14mm diameter lower O-ring injectors.
This kit includes:
-Black Anodized Laser Etched Aluminium Fuel Rails (x2)
-Black Anodized Ver 5/6 JDM Conversion Fuel Rail Mount (x2)
-Black Anodized and Laser Etched Injector Seats (x4)
-Phenolic Thermal Insulating Press-In Spacers (x4)
-Phenolic Thermal Insulating Press-In Bolt Washers (x4)
-Stainless Steel Hardware
-Black Anodized Aluminium 6AN Male Fittings (x4)
-Black Anodized Aluminium 8AN ORB Plugs (x4)
Do I need a pulse damper?
The opening and closing of the injectors creates pressure pulses in the fuel rail, which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a pulse damper should be used (especially with high flow injectors). The internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle. The optional Radium 20-0176 fuel pulse damper can be used in any of the three -8AN ORB ports on these fuel rails.
