Radium Engineering Top Feed Fuel Rail Conversion – Toyota 2JZ-GTE

Upgrade your 2JZ-GTE's fuel system with the Radium Engineering Top Feed Fuel Rail Kit, designed for both VVT-i and non-VVT-i engines using the factory intake manifold. This kit converts the restrictive OEM side feed injector setup to a high-flow top feed configuration, compatible with modern performance injectors.

Overview
CNC-machined from 6063 aluminium and featuring a 17.5mm (0.69") internal bore, this fuel rail can support extreme horsepower applications and all fuel types including E85. It includes both short and tall mounting spacers, allowing for flexible fuel injector sizing and optimal throttle body clearance. Integrated injector seats accept 14mm O-ring injectors and feature Viton O-rings to seal boost pressure.

Fuel Injector Compatibility
Compatible with any injector using 14mm O-rings. Below are common options:

With Tall Spacers:

• Injector Dynamics ID1050-XDS-48-14-14

• Injector Dynamics ID1300-XDS-48-14-14

• Injector Dynamics ID1700-XDS-48-14-14

• Injector Dynamics ID2600-XDS-48-14-14

With Short Spacers (for throttle body clearance):

• Injector Dynamics ID1050-XDS-34-14-14

• Injector Dynamics ID1300-XDS-34-14-14

• Injector Dynamics ID1700-XDS-34-14-14

• Injector Dynamics ID2600-XDS-34-14-14
