Nissan VG33ER 3.3L V6 Remanufactured Engine – 38169

Description

Pressurize Roots-type supercharger manifolds and maintain hydrodynamic bearing wedge film stability under 210 horsepower output across demanding regional commercial patrol schedules without hesitation using the Nissan VG33ER Supercharged Remanufactured Engine. Built under casting tag 38169 for Frontier and Xterra supercharged models, this 12-valve SOHC V6 powerplant delivers dependable high-torque pulling capability under severe loads.

High-nickel cast iron block architecture provides exceptional rigidity and features an Ra 25 micro-inch deck surface finish. A precision-balanced forged steel crankshaft rotates on tri-metal journal bearings, driving forged steel connecting rods and dish-top hypereutectic pistons with anti-friction skirt coatings. Sump capacity measures 4.5 quarts in a stamped steel oil pan, while high-velocity oil passages protect valvetrain components across an overall dry engine mass of 385 lbs.

Key Features of Nissan VG33ER Supercharged

Commercial fleet operators buy Nissan VG33ER Supercharged remanufactured engine packages to eliminate chronic vehicle downtime across challenging steep-grade transit routes. Automated dyno cell testing ensures exact boost containment and balanced cylinder compressions under full load.

• Roots-type supercharger boost integration produces immediate low-end torque for heavy trailer towing
• Multi-layer steel cylinder head gaskets maintain combustion seals against continuous boost pressure
• Plateau diamond honed cylinder bores eliminate piston ring blow-by and oil vapor emissions
• Precision line-honed main bearing saddles ensure true crankshaft alignment and lower drag
• High-flow internal trochoid oil pump provides 55 PSI cruising lubrication to protected bearings
• Induction-hardened valve seat inserts resist wear under prolonged continuous fleet operation
• Nissan VG33ER long block units pass rigid non-destructive ultrasonic flaw testing

Supercharged Power Thermal Boundaries

This supercharged V6 engine outputs 210 horsepower at 4800 RPM alongside 246 lb-ft continuous torque at 2800 RPM using an 8.9:1 compression ratio. Dynamic cylinder cranking compression tests between 165 and 180 PSI across all six cylinders. Normal coolant operating temperatures hold between 185°F and 205°F, backed by 20 PSI hot idle oil pressure and 58 PSI cruising pressure. Radiator thermal rejection capacity measures 3600 BTU per minute under Severe Commercial Fleet duty cycle standards.

Driveline Crankshaft Interface Parameters

The rear crankshaft flange uses a six-bolt flexplate mounting pattern with an engineered 1.259-inch pilot hole dimension. Front crankshaft snout measures 1.181 inches with a precision keyway for timing belt sprocket location. Dial indicators measure crankshaft axial thrust endplay between 0.003 and 0.007 inches across all finished builds.

Pre-Lube Guidelines Servicing Limits

Technicians must prime internal engine oil passages with an external pressure tank and inspect supercharger drive gears before initial ignition. Conduct a twenty-minute cam run-in procedure at 2000 RPM using high-zinc break-in lubricant. This engine is not engineered for smaller supercharger pulleys exceeding factory boost limits, nitrous systems, or trailer weights exceeding chassis ratings.

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