If you're looking to boost your Toyota Supra MK3's fuel delivery system, the Radium Engineering Fuel Rail is just what you need. With a generous 0.69" internal bore, this fuel rail is designed to meet all your engine's power needs while ensuring smooth performance on the road or track.
CNC machined from durable 6063 aluminum, this fuel rail features a sleek black anodized finish, complete with laser etching for that premium look. It's not just about aesthetics; this design is built to last, providing you with a reliable component that stands up to the rigors of high-performance driving.
The Radium fuel rail is compatible with OEM 1JZ-GTE VVT-i top-feed fuel injectors, as well as any aftermarket injectors that fit the factory setup. With injector bores measuring 11mm, it offers flexibility for your fuel system. Plus, it accommodates all fuel types, including popular alcohol mixtures like E85, making it a versatile choice for any enthusiast.
Worried about installation? Don't be! This fuel rail comes with lightweight billet aluminum mounting feet for added strength, and it utilizes stainless steel hardware to prevent corrosion. You can easily reuse the factory mounting bolts and plastic insulating spacers, so make sure you have those handy before you start.
Unlike the previous model (20-0268), this fuel rail (20-0768) is fully compatible with all 1JZ-GTE VVT-i engines, including those equipped with the ETCS-i throttle body. If you want to keep your OEM fuel pressure regulator, just grab the 14-0285 8AN ORB to M12x1.25mm fitting, and you're all set!
Upgrade your fuel system with the Radium Engineering Fuel Rail and experience the difference in performance and reliability. Your Supra deserves the best!
