Fuel Injector Adapter - Nissan Base

Overview

The Haltech Fuel Injector Adapter - Nissan Base solves the common fitment challenge when upgrading to high-flow injectors in Nissan builds. This precision adapter allows proper installation of 1/2 length (34mm) extended-tip injectors with 14mm O-rings into standard Nissan intake manifolds, maintaining perfect seal integrity and eliminating fuel leaks that can destroy builds.

Technical Specifications

• Part Number: HT-080008
• Injector Length: 1/2 length (34mm) with extended tip
• O-Ring Configuration: 14mm top and bottom O-rings
• Base Compatibility: Nissan intake manifold O-ring system
• Material: Precision-machined fuel-safe construction

Why You Need This

When building serious power in SR20, RB25/26, or VQ engines, standard Nissan injectors become the bottleneck. High-flow aftermarket injectors rarely match OEM dimensions exactly — different tip lengths, O-ring sizes, and mounting configurations create fitment nightmares. Without proper adapters, you're looking at fuel leaks, poor atomisation, or injectors that simply won't seat correctly in the manifold.

This adapter is essential for SR20DET turbo builds pushing beyond 300bhp, RB engine swaps requiring larger injectors, and any Nissan EFI conversion where injector upgrade is critical. The extended tip design ensures proper spray pattern positioning within the intake port, whilst the dual 14mm O-ring configuration maintains fuel system integrity under pressure. We've used these extensively in our workshop for everything from S13/S14 drift builds to high-power R32/R33/R34 projects where injector sizing becomes critical for reliable tune delivery.

ECU & System Compatibility

Compatible with all Haltech Elite and Nexus ECU systems managing fuel injection duties. Works perfectly with Elite 550/750/1000/1500/2000/2500 and Nexus R3/R5 installations where upgraded injectors are specified. Essential component for any Nissan platform running aftermarket engine management requiring non-OEM injector fitment.
