Radium Fuel Rails | Toyota 1JZ-GTE / 3S-GE / 3S-GTE (20-0768 / 20-0235 / 20-0949 / 20-0849)

The 1JZ and 3S families split on valve timing and generation, and the rails follow those splits exactly.

Radium Engineering fuel rails for Toyota 1JZ-GTE and 3S engines, CNC machined billet aluminum with AN ORB ports. The VVT-i 1JZ takes an upgrade rail; the non VVT-i takes a top feed conversion.

Choose Your Engine

• Fuel rail, 1JZ-GTE VVT-i (20-0768): upgrade rail
• Top feed conversion, 1JZ-GTE non VVT-i (20-0235)
• Fuel rail, 3S-GE / 3S-GTE Gen 3-5 (20-0949)
• Fuel rail, 3S-GE / 3S-GTE Gen 1-2 (20-0849)

What You'll Feel

• Fuel flow that keeps pace with a built or boosted JZ or 3S
• Access to the top feed injector market on the non VVT-i conversion
• ORB ports for a regulator, gauge, or pulse damper

Features

• CNC machined billet aluminum, anodized
• AN ORB threaded ports
• Stainless steel mounting hardware
• Compatible with all fuel types including E85

The Details

Two separate fitment splits apply here. On the 1JZ-GTE, valve timing decides the part: the VVT-i engine takes the 20-0768 upgrade rail, while the non VVT-i takes the 20-0235, which is a conversion rail moving you from side feed to top feed injectors. Those are different products doing different jobs, not two sizes of the same thing.

On the 3S engines, generation decides it: Gen 1-2 take the 20-0849 and Gen 3-5 take the 20-0949. Both cover the naturally aspirated 3S-GE and the turbocharged 3S-GTE within their generation range.

Fittings and hose are selected separately.

Kit Includes

• Fuel rail with mounting hardware
• NOT included: AN fittings and fuel injectors

Applications

• 20-0768: Toyota 1JZ-GTE with VVT-i
• 20-0235: Toyota 1JZ-GTE non VVT-i, top feed conversion
• 20-0949: Toyota 3S-GE and 3S-GTE, Gen 3-5
• 20-0849: Toyota 3S-GE and 3S-GTE, Gen 1-2

Important Notes

• Confirm VVT-i or non VVT-i on the 1JZ; the rails are not interchangeable and one is a conversion
• Confirm 3S generation before ordering
• All fittings sold separately
