COMPATIBILITY

Toyota 1JZ-GTE (Non VVT-i only)

OVERVIEW

Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. They are CNC machined from 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. The kit includes 2 different sets of mounting feet allowing various height fuel injectors to be used. The anodized aluminum mounting feet secure the fuel rail to the intake manifold reusing the OEM Toyota thermal insulating spacers.

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.

FUEL INJECTOR COMPATIBILITY

The kit includes 2 sets of mounting feet to suit two specific height injectors. The taller mount feet of the two allow the use of a universal 48mm tall injector with 14mm upper and lower o-rings. The shorter allow the use of the short 34mm injector with the same o-rings. Refer to the dimensional drawings below

Many injector manufacturers will have applications with these dimensions. Here are a few examples of applicable injector part number from Injector Dynamics:

48MM WITH TALL SPACERS

Injector Dynamics ID1050-XDS-48-14-14
Injector Dynamics ID1300-XDS-48-14-14
Injector Dynamics ID1700-XDS-48-14-14
Injector Dynamics ID2600-XDS-48-14-14

34MM WITH SHORT SPACERS

Injector Dynamics ID1050-XDS-34-14-14
Injector Dynamics ID1300-XDS-34-14-14
Injector Dynamics ID1700-XDS-34-14-14
Injector Dynamics ID2600-XDS-34-14-14

Fuel injectors are NOT included and must be purchased elsewhere.

PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN ORB.

8AN ORB Adapter Fittings can be found HERE
8AN ORB Direct Mount Regulators can be found HERE
8AN ORB Fuel Pulse Dampers can be found HERE
Fuel Pressure Gauge Adapters can be found HERE

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.

To reuse the OEM fuel pressure regulator, select the 14-0285 8AN ORB to M12x1.25mm Fitting
