Toyota MK5 Supra Port Injection Kit

Click here to download installation instructions (PDF)

The Radium Engineering Port Injection Kit (PIK) is installed 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.

The PIK adapter plate can also be used as a simple intake manifold spacer without using the fuel rail. All that is required are 2AN ORB Plugs shown below.

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

These 4 adapters install into the underside of the vanity engine cover and make up for the intake manifold shifting.

VEHICLE COMPATIBILITY
2020+ Toyota GR Supra (A90/A91)
2018+ BMW Z4 (G29)

NOTES:
1. Compatible with the 2nd generation B58TU engines listed below.
-B58B30O1 (B58B30B)
-B58B30M1 (B58B30C)
2. NOT compatible with the 1st 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 depicted below. The upper and lower injector O-rings must be 14mm diameter.

PORTS AND FITTINGS

The fuel rail features 2 threaded ports that are tapped for 8AN ORB.

8AN ORB Adapter Fittings.
8AN ORB Direct Mount Regulators.

If building a custom fuel setup, appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. 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 20-0735.
2. See the 20-0753-PK (below) for a plumbing kit that provides the necessary adapter fittings and hose to connect to the OEM fuel line.
3. Because the PIK will space the intake manifold of the head, an aftermarket charge pipe will be required for the throttle body connection.
4. Compatible with all fuel types including popular alcohol mixtures such as E85.

20-0753-PK FUEL RAIL PLUMBING KIT, MK5 SUPRA
This kit permits the OEM low pressure fuel feed hose to be connected to the rear of the port injection fuel rail. Installs in under 10 minutes. If using an independent port injection fuel system (see Radium 20-0760 fuel pump hanger), this plumbing kit would not be required.

INCLUDED

-SAE Quick Connect Tee PTFE Hose Assembly
-Preassembled 6AN PTFE Fuel Hose
-8AN ORB to 6AN Male Fitting
-8AN ORB Plug
