Component and Systems Overview

This comprehensive technical reference covers every aspect of the E-BNR32 chassis. Designed for professional mechanics and dedicated DIY builders, the manual spans foundational maintenance to advanced drivetrain and electrical diagnostics. The engine section thoroughly outlines the ECCS (Electronically Concentrated Engine Control System), twin-turbocharger architecture, fuel injection parameters, and cooling system requirements. Factory-grade coverage extends to the chassis, body, and specific climate control components.

For the daily shop environment, utilizing these exact factory specifications helps eliminate diagnostic trial-and-error and accelerates bay turnaround times. Technicians will find step-by-step instructions for high-labor jobs that typically demand an expensive specialty shop visit. This includes executing a complete timing belt replacement, tearing down the twin-turbocharger assembly, isolating the front propeller shaft for 4WD braking performance checks, and calculating precise shim thicknesses for intricate valve clearance adjustments.

Additional documentation highlights critical electronic troubleshooting using the Nissan CONSULT diagnostic system, alongside region-specific design modifications. Organized intuitively by functional area, technicians can quickly access exact RB26DETT parameters, including intake and exhaust valve clearances, belt tensioning, and compression limits. The manual provides visual guidance outlining the removal and installation of complex assemblies like the intake collector, throttle chambers, and turbochargers, ensuring correct alignment marks and vacuum routing are understood.

Technical Specification Highlights

Technical highlights detailed in the manual include the exact 2,568 cc displacement and 8.5:1 compression ratio of the RB26DETT powerplant. Crucial clearances, such as the 0.51 mm intake valve specification, and performance targets like the 78–88 kPa (11–13 psi) turbocharger outlet pressure, are clearly tabulated. The overall cooling system capacity is specified at 9.0 liters.

*Important Safety Notice: Certain procedures involve extreme hazards, such as handling the RB26DETT exhaust valves that contain metallic sodium and react violently if exposed to water.
