Nissan Pulsar NX CA16DE 1.6L L4 Engine 1986-1987

Description

Enthusiasts battle chronic head gasket failure and worn valve guides before installing this Nissan Pulsar CA16DE Remanufactured Engine. Each 1.6L 4-Cylinder 16-Valve DOHC long block features diamond-surfaced cast iron decks and align-honed main saddles. Technicians must perform pressurized oil priming before initial start and execute an exact 500-mile break-in oil change to protect high-revving valvetrain components.

Built with cast iron block casting CA16DE, this rigid closed-deck engine block maintains bore concentricity under high engine speeds. The rotating assembly features a micro-polished forged steel crankshaft, balanced forged steel connecting rods, and oversized hypereutectic pistons with anti-friction skirt coatings. The 16-Valve DOHC aluminum cylinder head receives diamond deck resurfacing for head gasket retention. Dry weight measures 240 lbs within crated dimensions of 36in length by 36in width by 36in height. Oil capacity equals 3.7 quarts.

Key Features of Nissan CA16DE

Classic Japanese sport compact builders buy Nissan CA16DE remanufactured engine long blocks to restore high-revving throttle response and factory emission compliance. This long block replacement provides factory-matched machine tolerances for transverse front-wheel-drive sports coupes.

• Dual overhead camshaft cylinder heads receive CNC multi-angle valve seat cutting to maintain 0.001in runout.
• Diamond plateau honed cylinder walls establish an Ra 14 micro-inch crosshatch finish for ring seating.
• Micro-polished crankshaft journals eliminate runout to protect bi-metal rod bearings under load.
• Align-honed cast iron main bearing saddles support smooth crankshaft rotation up to redline RPM.
• Manganese-bronze valve guides receive precision reaming to eliminate oil consumption past valve stems.
• Multi-layer composite cylinder head gaskets ensure combustion chamber seal integrity under extreme thermal stress.
• New high-grade cylinder head bolts supply uniform clamp loads across all 4 combustion bores.

Dyno Bench Clearance Machining Specifications

Dyno cell spin testing verifies mechanical oil gallery pressurization and power output prior to crate shipment. The 1.6L 1597cc DOHC engine produces 113 HP at 6,400 RPM and 99 ft-lbs of shaft torque at 4,800 RPM. Main journal oil clearance holds between 0.0010in and 0.0014in, while connecting rod clearance measures 0.0011in to 0.0014in. Individual cylinder compression gauges verify 180 PSI across all 4 cylinders. Hot engine oil pressure maintains 55 PSI at 3,000 RPM with regulated coolant temperatures steady at 190°F.

Vehicle Fitment Drivetrain Guide

This engine fits 1986 to 1987 Nissan Pulsar NX sport coupes equipped with the 1.6L 1597cc DOHC CA16DE engine carrying block casting CA16DE. Compatible drivetrains include transverse front-wheel drive paired with 5-Speed manual transaxles or 3-Speed automatic transmissions. This long block does not fit 1.6L SOHC E16 engines, later 1.8L CA18DE platforms, or turbocharged CA18DET models due to divergent stroke dimensions, crank snout configurations, and intake manifold runners.

Installation Protocol Service Requirements

Technicians must inspect distributor drive alignment, check crankcase ventilation hoses, and verify throttle linkage travel during installation. Operational warnings restrict deployment in custom forced induction turbo conversions exceeding 6 PSI boost on stock compression pistons or non-vented track chassis lacking auxiliary oil coolers.

• Pre-fill the oil filter and prime engine lubrication passages with 10W-30 conventional motor oil.
• Drain initial break-in oil and install a replacement oil filter at the 500-mile service point.
• Check ignition base timing with a timing light and inspect timing belt tension at 1,500 miles.
