Radium Engineering Port Injection Kit | 2020-2021 Toyota Supra

2020-2021 Toyota Supra Port Injection Kit by Radium Engineering

The Radium Engineering Port Injection Kit (PIK) installs between the intake manifold and the cylinder head. It permits the use of port injectors for the additional fuel required for highly-modified B58TU engines. This does NOT replace the OEM direct injection system.

The fuel rail is CNC machined from extruded 6063 aluminum and laser etched for a high quality surface finish. Both end ports are machined with 8AN ORB (3/4-16 female) threads.

The injectors are mounted at a calculated angle to ensure proper spray into the center of the intake ports without sacrificing interference from surrounding components.

Relocation hardware is provided to allow the OEM engine vanity cover to be reused.

This kit is designed for specific top feed fuel injectors with upper and lower O-ring spacing, as depicted below. The upper and lower injector O-rings must be 14mm in diameter.
