Radium Port Injection Kit to suit Toyota MK5 A90 Supra

The Radium Engineering Port Injection Kit (PIK) is designed to be used with highly-modified B58TU engines. It installs between the intake manifold and the cylinder head to allow for the use of port injectors. The kit includes a CNC machined fuel rail made from extruded 6063 aluminum with 8AN ORB threads. The injectors are mounted at a calculated angle to ensure proper spray into the intake ports and can also be used as an intake manifold spacer without the fuel rail. The kit is compatible with the 2020+ Toyota GR Supra (A90/A91) and the 2018+ BMW Z4 (G29). It is designed for specific top feed fuel injectors with 14mm diameter upper and lower O-rings. The fuel rail features 2 threaded ports tapped for 8AN ORB, and appropriate fittings must be selected for custom fuel setups. The kit includes an anodized aluminum PIK adapter plate, anodized aluminum fuel rail, engine cover relocation hardware, B58TU intake port gaskets, and stainless steel hardware. Some additional components such as fuel injectors, port fittings, fuel hose, wiring, and charge pipe are not included in the kit. An independently regulated high horsepower port injection fuel pump system, an aftermarket charge pipe for the throttle body connection, and all fuel types including E85 are compatible with the kit. Additionally, there is an optional plumbing kit (20-0753-PK) available to connect the OEM low pressure fuel feed hose to the port injection fuel rail.
