86-93 Toyota Celica 3S-GTE GT-Four
86-93 Toyota Celica 3S-GTE All-Trac
*1st gen 3S-GTE are compatible. They simply do not require the provided injector seats or the billet mounting feet.

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 on the product pages can be used as a reference guide.

OVERVIEW
Manufactured with a large 0.7' internal bore, the Radium Engineering fuel rail can support all necessary engine power requirements. 

INJECTORS
The machined injector ports in the fuel rail are compatible with 11mm upper injector O-rings.

1ST GENERATION 3S-GTE
The fuel rail is compatible with the OEM top feed fuel injectors (or equivalent). No modifications are needed. 

2ND/3RD GENERATION 3S-GTE
These engines came with side feed fuel injectors which are NOT compatible with the Radium Engineeirg fuel rail. When the provided Radium Engineering injector seats are installed into the cylinder head injector ports (shown below), aftermarket injectors that are '48mm tall' with 11mm upper O-rings and 14mm lower O-rings must be used.

The following universal injectors have been verified to be compatible, however there are others on the market that will work that are not listed here.

Injector Dynamics ID1050-XDS-48-11-14
Injector Dynamics ID1300-XDS-48-11-14
Injector Dynamics ID1700-XDS-48-11-14
Injector Dynamics ID2600-XDS-48-11-14
