0 in stock
PORTS AND FITTINGS
The fuel rail ports are tapped for 8AN ORB. 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 below can be used as a reference guide.
Compatible with all Toyota 2JZ-GTE engines (VVTi and non-VVTi)
Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. They are CNC machined from a custom 6063 aluminum, media blasted, black anodized, and laser etched for a high quality surface finish. This kit is compatible with all fuel types including popular alcohol mixtures such as E85.
The Radium fuel rail converts the OEM side feed fuel injector setup to top feed, allowing the use of high flow fuel injectors (NOT INCLUDED). The kit includes 2 different sets of mounting feet allowing various height fuel injectors to be used (tall spacers shown below).
The anodized aluminum mounting feet secure the fuel rail to the intake manifold reusing the OEM Toyota thermal insulating spacers (P/N: 90561-08009).
The fuel injector bores and the included press-fit injector seats are designed for 14mm injector O-rings. These seats include O-rings to prevent boost pressure leaks. They are CNC machined billet aluminum, anodized, and laser etched. Below are some of the many fuel injectors that are a direct fitment with this Radium fuel rail kit.
Use the tall spacers to accomodate this size injector:
To permit increased throttle body clearance, we recommend using the short spacers in conjunction with the injector sizing described below:
