Radium Fuel Rail Kit - Nissan Skyline R32 (RB20DET)

Radium Fuel Rail Kit - Nissan Skyline R32 (RB20DET)

Application: Nissan RB20DET silver top (1989–1993), e.g. Skyline R32
Part Type: Upgrade fuel rail (rail only)
Part Number: 20-0757

The Radium 20-0757 is a high-flow upgrade fuel rail for the 1989–1993 Nissan RB20DET "silver top". It has a large 0.69" internal bore to support high power levels and is CNC machined from a custom 6063 aluminium extrusion, black anodised and laser etched, with lightweight features and integrated gusset mounts.

This is an upgrade rail, not a top feed conversion: the OEM injectors can be reused, or OEM-equivalent injectors with an 11mm upper O-ring. The rail is supplied without fittings – a complete bolt-on plumbing kit (20-0217-PK) is available separately.
