RADIUM ENGINEERING Toyota 1JZ-GTE non-VVTi Engine Top Feed Fuel Rail

Radium Engineering Fuel Rail 20-0235 – Top-Feed Conversion for Toyota 1JZ-GTE (non-VVT-i)

Lightweight, plug-and-play fuel rail that converts the factory side-feed injector layout to 14 mm top-feed on non-VVT-i 1JZ-GTE engines. Provides ample flow for high-power builds while remaining fully E85 compatible.

• CNC-machined 6063/6061 aluminum body, black anodized – low weight, corrosion-resistant, laser-etched branding.

• Large 0.69″ (≈ 17.5 mm) internal bore and three -8 AN ORB ports deliver fuel for 900 hp+ projects.

• Includes two bracket sets (tall & short) allowing use of 34 mm or 48 mm height injectors without manifold mods.

• 14 mm injector seat adapters with O-rings seal the rail to the manifold and prevent pressure loss.
