radium fuel pressure regulator rallysport

When the provided Radium injector seats are installed into these air-assist intake manifolds, an aftermarket injector that is 60mm long with 11mm upper O-ring and 14mm lower O-ring must be used. Air-assist intake manifolds require the Radium injector seats in order to use universal aftermarket fuel injectors, as shown in the picture below. These engines use a unique OEM fuel injector that is not replicated in the aftermarket. Late model (and California-spec) 2JZ-GE engines use Toyota air-assist emissions equipment. DO NOT USE THE INJECTORS LISTED BELOW WHICH ARE FOR AIR-ASSIST ENGINES ONLY.ĪFTERMARKET INJECTORS ON 2JZ-GE ENGINES WITH AIR-ASSIST If preparing to use aftermarket fuel injectors, read below.ĪFTERMARKET INJECTORS ON 2JZ-GE ENGINES (WITHOUT AIR-ASSIST)įor engines that do NOT use Toyota air assist equipment, use your preferred injector manufacturer's suggestion for OEM equivalent fuel injectors.

This includes non VVT-i and VVT-i engines as well as air-assist and non air-assist injectors. The Radium Engineering fuel rail features 11mm injector bores making it compatible with ALL factory Toyota 2JZ-GE (Non Turbo) fuel injectors. For these setups, an aftermarket fuel pressure regulator will be required. However, early model 2JZ-GE vehicles use a traditional fuel system with the FPR mounted directly to the fuel rail. Late model 2JZ-GE vehicles use a returnless fuel system where the fuel pressure regulator (FPR) is integrated into the pump assembly. INFORMATION REGARDING OEM FUEL PRESSURE REGULATOR Make sure these are present before beginning installation. IMPORTANT: The fuel rail re-uses the factory mounting bolts and plastic spacers. NOT compatible with the 2JZ-GTE (Turbo) engine. If looking for the Toyota 2JZ-GTE fuel rail, click HERE. For flexibility, the fuel rail features four 8AN ORB ports and is compatible with all fuel types including popular alcohol mixtures such as E85. The Radium fuel rail for the 6-cylinder Toyota 2JZ-GE (Non-Turbo) engine is manufactured with a large 8AN ORB internal bore supporting all horsepower requirements. They are CNC machined from 6063 aluminum, black anodized, and laser etched for a high quality surface finish. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide. 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. However, the front port is not useable unless the OEM engine harness is modified.ĨAN ORB Adapter Fittings can be found HERE.ĨAN ORB Direct Mount Regulators can be found HERE.ĨAN ORB Fuel Pulse Dampers can be found HERE.įuel Pressure Gauge Adapters can be found HERE.Īppropriate fittings must be selected based on the specific application. Nothing else is required.This fuel rail features four ports (both ends and two on the bottom) that are female tapped for 8AN ORB fittings. All necessary hardware and adapter fittings are included. The complete 20-0932-0X kit is shown below. Furthermore, it is compatible with alcohol blends of fuel including methanol, ethanol, and E85. This kit is suitable with all gasoline types including unleaded, leaded, oxygenated, and pre-mixes. Vacuum Plug: A black oxide stainless steel screw that is used to maintain a constant (non dynamic) fuel pressure. Push-To-Connect: A nickel-plated brass fitting with Buna-N O-rings that is compatible with hard plastic 1/4' OD tubing.Ĥ. 3AN Male Fitting: A black zinc-plated adapter machined from high strength steel that is compatible with 3AN hose ends.ģ. Barbed Fitting: A black zinc-plated 3/16' (5mm) barb machined from high strength steel that is compatible with the following vacuum hoses: 5/32' (4mm), 3/16' (5mm), and 7/32' (6mm).Ģ. There are 4 interchangeable 10-32 threaded vacuum port fittings provided to cover all scenarios.ġ. It permits the installer to quickly point the vacuum fitting in any direction with no tools required. The RA-series regulators feature a 360 degree swiveling vacuum reference port that is double O-ring sealed. Every detent permits 1psi (+/-0.5psi) of adjustment depending on current fuel pressure. To aid in adjusting pressure, there are incremental detents that provide haptic feedback to the user. With a simple turn of the knob, pressure will be increased or decreased. A jam nut and set screw are no longer required. The RA-series regulators feature the first tool-less pressure adjustment.

The OEM FPR is replaced with an RA-Series FPR.

For information on Radium Engineering fuel filters, go HERE. This fuel pressure regulator (FPR) and fuel filter is a bolt-in kit designed specifically for the 2001-2006 BMW (E46) M3 using factory fuel lines. The OEM fuel filter is replaced with a high-flow Radium Engineering fuel filter. The filter is compatible with all fuel types.
