PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN ORB.

• 8AN ORB Adapter Fittings
• 8AN ORB Direct Mount Regulators
• 8AN ORB Fuel Pulse Dampers
• Fuel Pressure Gauge Adapters

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. Dimensional drawings on the product pages can be used as a reference guide to verify clearance.

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 do not require the provided injector seats or the billet mounting feet.

OVERVIEW

Manufactured with a large 0.7" internal bore, the 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-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 fuel rail. When the provided injector seats are installed into the cylinder head injector ports, 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:

• 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

Injector Dynamics injectors are shown on cylinders 1-2. Machined mid-height "48mm" Bosch EV14 injectors are shown on cylinders 3-4.

FEATURES

• Anodized surface finish for wear and corrosion resistance
• Injector seats compatible with high flow injectors
• Lightweight aluminum construction
• Inner bore diameter: 0.7 inch
• Reuses thermal insulating spacers
• Stainless steel hardware
• No special tools required for installation
