B58TU Port Injection Kit

The Radium Engineering Port Injection Kit (PIK) is engineered to supplement the OEM direct injection system in highly-modified B58TU engines. This kit installs between the intake manifold and the cylinder head, allowing for the addition of port injectors to meet increased fuel demands. The fuel rail is precision CNC-machined from extruded 6063 aluminum, featuring an anodized finish and laser-etched branding for a premium look. Both ends of the fuel rail are equipped with 8AN ORB (3/4-16 female) threads, providing versatile connection options. The injectors are strategically angled to ensure optimal spray into the intake ports without causing interference with surrounding components. The PIK adapter plate can also serve as a simple intake manifold spacer; use of 2AN ORB Plugs is then required if the fuel rail is not utilized. Relocation hardware is included to allow the factory engine vanity cover to be refitted, compensating for the intake manifold's shift. This kit is compatible with all fuel types, including E85 and other alcohol mixtures. However, it is important to note that this kit is designed for specific top-feed fuel injectors with a 14mm O-ring diameter and a short 34mm body height; taller injectors cannot be used. An aftermarket charge pipe will be required due to the intake manifold spacing. The kit does NOT include fuel injectors, port fittings, fuel hose, wiring, or an injector controller. Compatibility is limited to 2020+ Toyota GR Supra (A90/A91) and 2018+ BMW Z4 (G29) models equipped with the B58B30O1, B58B30M1, or 2nd generation B58TU engines. It is NOT compatible with the 1st generation B58B30M0 (B58B30A) engines.
