Mazda RX7 FD3S Stage 2 Fuel kit

This is by far the best fuel kit available for the RX7 FD3S on the market today. It comes complete with a RADIUM performance primary and secondary fuel rail, NUKE performance fuel pressure regulator, NUKE performance fuel pressure gauge, and all hoses required to connect to the stock hard fuel lines in the engine bay.

 

The injectors supplied with this kit (if selected) are made by Evolved tuning as listed in the compatability list below

Evolved tuning 1650cc injectors

Evolved tuning 850cc injectors

 

All hoses are made from our NITRILE range of hose and fittings, as this is required for a push-on connection to the stock hard fuel lines. Use of this kit does require you to remove the stock ACV system (blanking kits are available as an option) and is designed around an un-modified engine bay (some fitment issues may arrise with use of other aftermarket parts)

 

An offset gauge adapter is supplied to be fitted on the return line to the fuel pressure regulator. This allows the use of a gauge or pressure sensor, without interfering with the ABS system.

PORTS AND FITTINGS


The Radium Engineering high flow primary fuel rail is for the 13B-RE and 13B-REW rotary engine found in the 1990-1995 Mazda/Eunos Cosmo and 1992-2002 Mazda RX7 FD3S. The aluminum fuel rail is anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements.


Insulating phenolic spacers and washers are included with stainless steel hardware to prevent thermal energy from conducting heat into the fuel.

The included 14mm lower injector seats (shown above) were designed specifically to be compatible with or without the OEM diffusers in place. They feature Viton O-rings making them suitable for boosted applications.

SECONDARY RAIL

PRODUCTS INSTRUCTIONS CAN BE FOUND HERE

 

This Radium Engineering secondary fuel rail is for the Mazda 13B-REW rotary engine.

With the use of the provided 2AN ORB plugs, this adaptable design permits both the OEM 2-port intake manifold (shown above) and aftermarket 4-port intake manifolds (shown below). 

The aluminum fuel rail is anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. The extra center port allows additional fuel system accessories such as the OEM fuel temperature sensor (using 14-0421 shown below), a pressure transducer, Radium fuel pulse damper, etc.

Insulating phenolic spacers and washers are included with stainless steel hardware to prevent thermal energy from conducting heat into the fuel. The two M8 extension mounts are made from stainless steel for superior strength and corrosion resistance.

For the OEM 2-port intake manifold, the included 20mm phenolic spacers, billet injector seats, and 2AN ORB plugs will be used. Also, for the required space, an air control valve delete for the OEM 13B-REW intake manifold (sold separately) is required. 

The included 14mm lower injector seats were designed specifically to be compatible with or without the OEM diffusers in place. They feature Viton O-rings making them suitable for boosted applications. NOTE: if using an Elite Rotary Shop 4-port intake manifold (shown below), 2 extra injector seats are required.

With this fuel rail, all lower intake manifolds variations are compatible with the fuel injectors listed below. For the Xcessive Manufacturing 4-port intake manifold, the included 11mm phenolic spacers will be used.
