Product details

Description

One rail kit covers the entire VQ dynasty, from the 350Z's DE to the 370Z's VHR.

The Radium Engineering Fuel Rails for Nissan VQ Engines are confirmed compatible with the VQ35DE, VQ35HR, and VQ37VHR: two rails machined from 6061 aluminum, black anodized for compatibility with all popular fuel types including E85, each carrying a large internal bore supporting all necessary engine power requirements and four 8AN ORB ports (2 ends, 2 bottom) for eight total. The 14mm injector bores accept OEM injectors and any aftermarket injectors with OEM VQ fitment, unique stainless steel mounts permit fitment across all the VQ engines, and OEM injector clips reuse on the VQ35DE and VQ35HR. This kit is rails and mounting hardware only, ideal for custom plumbing; the engine-specific plumbing kits (sold separately) make it plug and play.

What You'll Feel

  • Fuel delivery headroom for boosted VQ builds across three engine generations
  • Eight 8AN ORB ports opening pressure transducers, pulse dampers, and custom plumbing configurations
  • Factory injectors and clips carrying over on DE and HR engines
  • One confirmed-fitment kit spanning 350Z, 370Z, G35, G37, Q50, and Q60 platforms
  • E85 confidence from the anodized 6061 construction

Features

  • 2x fuel rails machined from 6061 aluminum, black anodized, large internal bore
  • 4x 8AN ORB ports per rail (2 end, 2 bottom); 8 total
  • 14mm injector bores compatible with OEM injectors and aftermarket injectors with OEM VQ fitment
  • Unique stainless steel brackets and hardware permit fitment across all VQ engines; OEM injector clips reuse on VQ35DE/VQ35HR
  • VQ35DE ONLY: two Radium 14-0150 8AN ORB plugs are required in one center port per rail due to the OEM manifold mounting bosses (sold separately)
  • All fuel types including E85; NO fittings included

The Details

The plumbing kits complete the picture, and each is engine-specific: the VQ35DE kit (20-0468) runs an SAE adapter to the OEM hard line under the vehicle, PTFE hoses to the rear rail ports, plugs and 6AN adapters for every port, and the 20-0460 adapter reusing the OEM pulse damper; the VQ35HR/VQ37VHR kit (20-0469) routes the same architecture to the front rail ports with two 20-0459 adapters reusing the OEM dampers. Radium's direct-mount pulse dampers also fit some of the 8AN ORB ports on the DE and HR, giving damping options beyond OEM reuse. One install note that catches DE builders: the OEM intake manifold mounting bosses require two 14-0150 plugs occupying one center port per rail, a DE-only quirk that does not apply to HR or VHR engines. Injector rule as always: OEM VQ fitment, dimensions confirmed with the injector manufacturer.
