Description

The single-cam KA24E deserves better fueling than 1989 gave it.

The Radium Engineering Fuel Rail Kit for the 1989-1993 Nissan 240SX serves the S13's KA24E-era fuel system: a CNC machined aluminum high flow rail, anodized and laser etched, replacing the OEM rail with a large internal bore supporting all necessary engine power requirements and threaded ORB ports for feed, accessories, and plugs. Factory injector compatibility keeps the install bolt-on, all fuels including E85 are welcome, and the S13's turbo and build ambitions finally get a delivery path to match.

What You'll Feel

  • Fuel delivery headroom for turbo KA builds and the S13's endless project ambitions
  • ORB ports opening regulators, dampers, and gauges the OEM rail never offered
  • Factory injectors carried over in OEM-spec bores
  • E85 confidence from the anodized aluminum construction

Features

  • High flow fuel rail for the 1989-1993 Nissan 240SX (KA24E single-cam era)
  • CNC machined aluminum, anodized, laser etched; large internal bore
  • Threaded ORB ports for feed, return, and accessories
  • Upgrade rail: OEM or OEM-equivalent injectors only (matching height and O-ring specs)
  • All fuel types including E85; fittings sold separately

The Details

The 89-93 chassis split matters at ordering time, since the early S13 carried the SOHC KA24E before the twin-cam KA24DE arrived, and Radium builds separate rails for each: this 20-0558 serves the single-cam cars, with the KA24DE rail and its conversion kits handling 1994+ and swapped applications. Port fittings are selected per your plumbing plan, factory-style or full AN, with Radium's ORB adapter catalog covering both paths and the usual O-ring lubrication discipline throughout. Injector upgrades follow the standard rule, OEM-equivalent dimensions confirmed with the injector manufacturer, flow rates from your tuner.

Kit Includes

  • 1x Anodized, laser etched high flow fuel rail with mounting hardware
  • Fittings and plumbing sold separately

Applications

  • 1989-1993 Nissan 240SX (S13, KA24E)
