MK5 Supra BMW Z4 Radium Engineering Port Injection Kit

Radium Engineering’s Port Injection Kit (PIK) installs between the intake manifold and cylinder head. It allows the use of port injectors for additional fuel needed on highly modified B58TU engines. This kit does NOT replace the OEM direct injection system.

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

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

The PIK adapter plate can also be used as a simple intake manifold spacer without using the fuel rail.

Relocation fittings are provided to permit reuse of the OEM engine cover.

These 4 adapters install into the bottom of the engine cover and compensate for the intake manifold's offset.

VEHICLE COMPATIBILITY

2020+ Toyota GR Supra (A90/A91)

2018+ BMW Z4 (G29)

NOTES:

1. Compatible with the second generation B58TU engines listed below.

-B58B30O1 (B58B30B)

-B58B30M1 (B58B30C)

2. NOT compatible with the first generation B58B30M0 (B58B30A) engine. FUEL INJECTOR COMPATIBILITY This kit is designed for specific top-feed fuel injectors with upper and lower O-ring spacing, as pictured below. Both the upper and lower injector O-rings must be 14mm in diameter. Deatschwerks 16U-00-0042-4 Deatschwerks 16U-00-0050-4 Deatschwerks 16U-00-0065-4 Deatschwerks 16U-00-0090-4 Deatschwerks 16M-00-1500-4 Deatschwerks 16M-00-2200-4 Fuel Injectors are not sold at Radium Engineering and must be sourced elsewhere. Ports & Connections Fuel rail features 2 threaded ports with 8AN ORB threads. What is ORB? If building a custom fuel system, proper fittings must be selected depending on the specific application. Ample clearance around the fuel rail port for larger fittings such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers is necessary. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide. INCLUDED -Anodized aluminum PIK adapter plate -Anodized aluminum fuel rail -Engine cover relocation hardware -B58TU intake port gaskets (x6) -Stainless steel hardware NOTES 1. Fuel injectors, port fittings, fuel hose, wiring, injector controller, charge pipe, etc. are NOT included in kit 20-0735. 2. See kit 20-0735-PK (below) for a plumbing kit that provides the necessary adapter fittings and hose to connect to the OEM fuel line. 3. For a high horsepower port injection fuel pump system with independent regulation, click HERE. 4. Because the PIK will space the intake manifold away from the cylinder head, an aftermarket charge pipe will be required for the throttle body connection. 5. Compatible with all fuel types including most common alcohol blends such as E85.
