1989 Nissan 240SX Service Manual 0EM

• Official OEM publication (Section B1 Supplement I, dated January 1991) detailing the exact SR20DET mechanical configuration for the S13 series
• Covers 1991 Nissan 180SX E-RPS13 and E-KRPS13 variants equipped with the 2.0L turbocharged engine
• Contains over 80 exploded-view component diagrams, complete system schematics, and accurate factory bolt-torque specifications

Mechanical System Documentation

The 1991 Nissan 180SX supplement focuses heavily on the SR20DET architecture. It provides a clear roadmap for major engine subsystems, including detailed assembly and disassembly logic. You will find complete structural breakdowns of the camshaft assembly, valve train, and timing chain integration. High-performance components get dedicated sections. This covers the turbocharger unit, exhaust manifold, and intercooler assembly. Working on turbocharged powertrains involves inherent risks and requires strict adherence to factory procedures to prevent severe component damage or personal injury. This documentation helps mitigate those risks by outlining the exact ECCS electronic control system layout, fuel injection maps, and complex vacuum piping arrangements specific to this platform.

Technical Specification Highlights

Accurate data is the backbone of any successful rebuild. This manual delivers comprehensive factory thresholds, highlighting torque values for critical stages like cylinder head bolts and camshaft brackets. It also lists base sensor reference values for troubleshooting idle control and timing systems. Need fluid capacities? The reference documents engine oil and cooling system volumes alongside precise clearance charts for piston rings and cam journals. Precise baseline tolerances for oil pressure and fuel system operation are mapped out across all mechanical overview sections.
