Radium Engineering Fuel Rail Toyota MR2 3S-GTE 90-99

Radium Engineering high volume fuel rail works on all Toyota 3S-GE and 3S-GTE, Gen 1-2 engines. Both ends of the rail are tapped to 8AN ORB female threads. These ports use positive o-ring seals instead of tapered pipe threads which commonly damage aluminum threads and lead to fuel leaks.
COMPATIBILITY
90-93 Toyota MR2 3S-GE
90-95 Toyota MR2 3S-GTE
85-93 Toyota Celica 3S-GE
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.


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

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

2ND GENERATION 3S-GE / 3S-GTE
These engines came with side feed fuel injectors which are NOT compatible with the Radium Engineering 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.
