Fuel Injector Adapter - 10.5mm Nissan RB26DETT GTR

Overview

Essential adapter for fitting shorter 48mm injectors into RB26DETT fuel rails designed for full-length 60mm units. Converts 14mm top O-ring injectors to work seamlessly with the GTR's standard 10.5mm bore fuel rails, maintaining proper sealing and fuel delivery under high-boost conditions.

Why You Need This

The RB26DETT's fuel rail was designed around specific injector dimensions, but modern high-flow injectors often come in shorter 48mm lengths with larger 14mm O-rings. Without this adapter, you're stuck with limited injector choices or expensive custom fuel rail modifications. This becomes critical on built GTRs pushing serious power where injector choice can make or break your tune.

We see this constantly with RB26 builds running big turbos or E85 conversions. Customers want to run proven injectors like ID1050X or Bosch EV14 units, but the dimensional mismatch creates sealing issues and poor fuel delivery. This adapter solves it properly, maintaining the fuel rail's original mounting points whilst giving you access to the full range of modern high-performance injectors. Essential for any serious GTR build where injector headroom matters.

ECU & System Compatibility

Works with any ECU system controlling fuel injection on RB26DETT applications. Particularly relevant for GTR builds running Haltech Elite or Nexus ECUs where precise injector data and flow characteristics are critical for optimal tuning results.
