Nissan CA16DE 1.6L L4 Remanufactured Engine – 9/86-8/87

Description

Secure high-RPM valvetrain stability and prevent cam lobe spalling under 113 lb-ft continuous torque demands across intensive light-duty courier routes without hesitation using the Nissan CA16DE 1.6L Remanufactured Engine. Built for 9/86 to 8/87 Pulsar NX platforms, this 16-valve DOHC inline-four powerplant provides agile acceleration and reliable mechanical endurance across demanding metropolitan commercial schedules.

High-strength cast iron block construction provides extreme structural stamina and features an Ra 28 micro-inch deck surface finish. A precision-balanced forged steel crankshaft spins within line-honed main bearing saddles, driving forged steel connecting rods and lightweight aluminum alloy pistons. Sump capacity measures 3.8 quarts within a stamped steel pan, while high-velocity oil passages protect the twin overhead camshafts across an overall dry engine mass of 255 lbs.

Key Features of Nissan CA16DE

Courier fleets buy Nissan CA16DE remanufactured engine packages to preserve vintage commercial chassis reliability and avoid catastrophic valvetrain failure. Automated dyno cell testing ensures precise combustion chamber pressure retention and responsive fuel atomization under load.

• Double overhead camshafts operate sixteen valves to maximize combustion chamber intake velocity
• Multi-layer steel cylinder head gaskets maintain dynamic combustion seals against thermal warping
• Plateau diamond honed cylinder bores prevent ring blow-by and eliminate excessive oil consumption
• Precision line-honed main journal bores eliminate crankshaft bearing binding and rotational drag
• High-flow internal trochoid oil pump maintains 50 PSI pressure across high-RPM highway operations
• Induction-hardened valve seat inserts resist wear under prolonged continuous fleet operation
• Nissan CA16DE long block units pass rigid non-destructive ultrasonic crack testing

Combustion Output Thermal Thresholds

This motor outputs 122 horsepower at 6400 RPM alongside 113 lb-ft continuous torque at 5200 RPM using a 10.0:1 compression ratio. Dynamic cylinder cranking compression tests between 170 and 185 PSI across all four cylinders. Normal coolant operating temperatures hold between 185°F and 200°F, backed by 18 PSI hot idle oil pressure and 52 PSI cruising pressure. Radiator thermal rejection capacity measures 2150 BTU per minute under Severe Commercial Fleet duty cycle standards.

Driveline Crankshaft Interface Parameters

The rear crankshaft flange uses a six-bolt flywheel mounting pattern with an engineered 0.826-inch pilot counterbore diameter. Front crankshaft snout measures 0.984 inches with a machined Woodruff keyway slot for timing sprocket retention. Dial indicators measure crankshaft axial thrust endplay between 0.003 and 0.007 inches across all finished builds.

Break-In Protocol Servicing Rules

Technicians must prime internal engine oil passages with an external pressure tank before turning the ignition key to protect fresh bearing surfaces from dry friction. Conduct a twenty-minute cam run-in procedure at 2000 RPM using high-zinc break-in lubricant. This engine is not engineered for aftermarket turbochargers, nitrous systems, or trailer towing weights exceeding vehicle chassis ratings.

• Inspect fluid reservoirs and accessory belts each shift
• Change motor oil and replace spin-on filter every 3500 miles
• Inspect timing belt drive and tensioner every twelve months
