When upgrading your Subaru EJ V3-6, choosing the right fittings is essential. Make sure to select fittings that match your specific application for a seamless installation. You'll want to ensure there's enough space around the fuel rail ports for larger accessories like fuel pressure regulators, gauges, and pulse dampers. To help you with this, you can refer to the dimensional drawings available on the product pages.
These "conversion" fuel rails make it easy to switch from the OEM side feed fuel injector setup to a top feed system, allowing you to use high-flow fuel injectors (please note, injectors are not included). With an internal bore of 14mm, these fuel rails are designed to meet all your engine's power needs. Crafted from solid 6061 aluminum, they are CNC machined, black anodized, and laser engraved to ensure a premium finish. Plus, they're compatible with all fuel types, including popular alcohol mixtures like E85. To help manage heat transfer from the intake manifold, we've included machined press-fit spacers that provide thermal insulation.
The four anodized and laser-etched billet injector seats create a secure receptacle for top feed fuel injectors. Designed specifically for injectors with 14mm lower O-rings, these seats ensure a snug fit for optimal performance.
For the 20-0569-02 conversion fuel rails, we've included adaptable mounting brackets that make it easy to fit a wide range of Subaru vehicles. Just a quick reminder: please avoid purchasing "WRX Fitment" injectors, as they are not compatible with this setup.
Upgrade your Subaru with confidence and enjoy the benefits of a top feed fuel system!
